The unparalleled talent of the country started from Harbin Institute of Technology

Chapter 210, Burnside Problem, one man alone fights against the global mathematics community?

On August 8, 1982, in the Sears department store in New York, USA, a very eye-catching product was placed in the most conspicuous shop position on the first floor: a cordless telephone!

There are also a large number of poster advertisements posted around the square, which are very conspicuous and can be seen as soon as you enter the department store.

After entering, most consumers couldn't help but stop and watch.

Cordless phones have been successfully launched on the market and are now considered high-tech products by many consumers.

The price of US$1982 per unit is a bit expensive, but for many consumers, they are still willing to pay for it.

In the United States today, the shadow of the economic crisis has just dissipated, or it has not completely dissipated, and the aftereffects are still continuing.

However, the oil crisis that began in early 1979 is almost over. The economic crisis it triggered actually had a greater impact on a certain group of unemployed people.

For most people, the impact is not significant.

Otherwise, American Hollywood movies in the past few years would not have had such high box office.

The shop selling cordless phones was crowded with people, and several sales clerks were so busy that they kept their feet on the ground. The sales talk that was originally unfamiliar to them became familiar to them in a very short time.

"You can try listening to it. Our cordless phones are not just mobile phones. As long as you are in your home, you can answer calls wherever you move around. Even if you take your phone to the yard to answer a call, the signal is still very good."

"Our cordless phone also uses the latest audio technology, which provides excellent sound quality and can reproduce the sound most realistically."

After listening to the salesperson's introduction, many people were attracted and stopped in front of the shop, unwilling to leave.

After hearing this, someone immediately discussed it with his wife next to him:
"Honey, why don't we buy one? We can replace the phone at home. You see, we just got our salary."

"But Jack, a telephone costs $1,982. It's still too expensive."

"Honey, believe me, we will definitely be able to make back this money soon. Buy it sooner and enjoy it sooner."

Damn capitalists, in order to sell goods as quickly as possible, even slogans like "buy early and enjoy early" have begun to take root in people's minds.

nonsense!

In order to achieve better sales of products such as electric bicycles and handheld game consoles, Wang Duoyu will of course talk about these sales techniques with Shang Zhongmin and other sales teams.

In fact, Shang Zhongmin and his team are also very capable. After using the sales skills provided by Wang Duoyu, they can certainly sell more products.

If the products developed by Harbin Institute of Technology can gain a foothold in the market, then Shang Zhongmin and his sales team will definitely be one of the major contributors.

"It's sold out, absolutely sold out, we need to keep ordering more."

Many agents called and after the information was summarized at Huaxin’s headquarters in the United States, it was transmitted back to Harbin Institute of Technology.

It was not until August 17 that Wang Duoyu was called to the secretary's office.

"Duoyu, the cordless phones are sold out. They're very popular in the US. It seems we were too conservative before."

As soon as Wang Duoyu sat down, he heard Liu Deben mention Huaxin Company's performance with great joy.

The cordless telephone was developed in mid-May, technical optimization was completed in mid-to-late June, and then the production line was debugged by mid-July, and production began.

In August, the product was launched overseas.

No one expected that it would become a hit as soon as it was launched.

Since the factory did not have much inventory, and Liu Deben and his colleagues even thought that sales were unlikely, they directly shipped all 4,800 cordless phones in the warehouse to the United States.

Unexpectedly, the sales volume was so hot.

In less than a week, 4,800 cordless telephones were sold out, which can be said to be a business miracle in the telephone industry.

"Secretary, this is a good thing. We can continue to add production lines and increase production to meet current market demand."

Wang Duoyu said with a smile, but Liu Deben poured cold water on him at this time:

"Duoyu, have you ever thought about what if this is just a gust of wind? After it blows, it's gone. What will you do if your products are unsalable?"

"Secretary, you should change your cautious character. You don't have much confidence in our products. This is definitely not acceptable."

In Wang Duoyu's opinion, Liu Deben is good in every way except that he is too cautious.

Obviously, sales are so hot right now, which is a good thing, so why has it become a passing fad?
Although being cautious is a good thing, there has to be a time for it, right?

If you are still considering so many consequences at this time, why not just shut down the factory and stop production? Then there will be no losses.

You want to make a lot of money but don’t want to take any risks. Where in the world is there such a good thing?

Liu Deben shook his head helplessly. He was not young anymore and was no longer old enough to fight and struggle.

If he were a little younger, maybe ten or twenty years older, he would certainly dare to give it a try.

But he is not!
It is best to be cautious. After all, Wang Duoyu is very brave and fighting. As the patriarch of Harbin Institute of Technology, he must tighten the reins at the appropriate time.

"Since the product has become so popular in North America, we must capitalize on this enormous wealth and increase production to sell more products before Motorola launches its phone."

Seeing Wang Duoyu so determined, Liu Deben had no choice but to agree to this matter.

Therefore, after receiving the order, Huaxin Company began large-scale purchases and also needed to recruit a large number of skilled workers.

After coming out of the secretary's office, Wang Duoyu went to the lecture hall in the mathematics department's teaching building for the monthly mathematics exchange and sharing session.

There are still many people in the tiered classroom today, and there are many unfamiliar faces.

For example, Zelmanov was sitting in the third row, looking at Wang Duoyu on the podium with a smile on his face.

Zelmanov arrived at Harbin Institute of Technology on August 3rd and was stunned when he arrived.

The Ice City Institute for Advanced Study actually has several Fields Medal winners, including Shing-Tung Yau, William Thurston, and Gerd Faltings.

Wow, the favorites for the next Fields Medal, that is, next year, are all in the Ice City.

Obviously these people are competitors, but at this moment, they are all in Ice City, and from time to time they can be seen gathering together to chat and communicate.

This is absolutely the pinnacle of academic freedom.

Everyone can speak freely here and discuss academic issues freely.

Zelmanov knew very well that the person who brought everyone together was Wang Duoyu, the emperor of the global mathematics community, who was standing on the podium at that moment.

After coming here, Zelmanov felt completely at ease.

Especially after he talked with Maxime, Jean Bourgain and others, he became more convinced of his choice.

Jean Bourgain was the first person from the Polar Bear Empire to come to Harbin Institute of Technology. He was one of the earliest members of the visiting scholar exchange group.

Therefore, when it comes to understanding Harbin Institute of Technology and Wang Duoyu, he has the most say.

Wang Duoyu said that people can come and go freely and there is indeed no problem.

Smale has been back and forth many times. If it weren't for his age, he would definitely settle down at Harbin Institute of Technology.

Most people who come to Ice City are very fond of mathematics and are relatively pure people.

These people don't think about political issues, they only think about themselves and mathematics.

So everyone stayed here.

Five or six rows behind Zelmanov, Li Damao, Jiang Shoucheng and Mai Zili sat together, looking at Wang Duoyu on the podium with excitement.

Although Jiang Shoucheng and Mai Zili are not students of the mathematics department, their mathematics skills are actually not bad. In this semester's final exam, they were able to get a score of 95 in advanced mathematics.

In college, exams are generally scored out of 100 points. For a school like Fudan University, their final exams are definitely not easy.

Of course, compared with the Department of Mathematics of Harbin Institute of Technology, it is still easier.

"Good afternoon, everyone. Today's lecture is divided into the first and second half. I want to talk about some things in the first half, um, to share some of my gains and thoughts on number theory and geometry."

On the podium, as soon as Wang Duoyu finished speaking, the expressions of the people below changed instantly.

What are your gains and thoughts?
What do you mean?
John Milnor and others listened attentively without saying a word, but they saw that Wang Duoyu had already started writing on the blackboard, explaining something as he wrote.

The reason why everyone stayed in Ice City was actually to work together to solve the geometric Langlands conjecture.

In the eyes of many mathematicians, Langlands's conception is a grand unified theory, and the difficulty level must be very high.

The geometric Langlands conjecture was developed on the basis of the Langlands program, and it focuses more on the duality between algebraic varieties and moduli spaces.

Everyone can understand that Wang Duoyu is a very capable person, but no one expected that he would not start with the geometric Langlands conjecture, and then go to study number theory and geometry?
Could it be that he has made a new breakthrough in this regard?

After all, the Langlands Program is all about number theory, algebraic geometry, and representation theory of reduction groups.

As Wang Duoyu explained, everyone listened attentively. Some understood, while others did not.

"Da Mao, do you understand?"

Jiang Shoucheng was a little confused. The more he listened, the more troubled he became. Out of boredom, he saw that his little friend Li Damao was listening very seriously, so he couldn't help but write a question on the manuscript paper and handed it to him.

However, Li Damao ignored the other party.

Because when Wang Duoyu is teaching, if you don't listen carefully, you only need to lower your head slightly to pick up a pen, and when you look up again, you will definitely not understand.

So in order to avoid such a situation, Li Damao naturally would not be absent and refused to chat with Jiang Shoucheng.

Seeing that his friend ignored him, Jiang Shoucheng had no choice but to look at Mai Zili next to him. It turned out that the latter was also listening very seriously.

"No, so I'm the only one who doesn't understand?"

Soon, the first half was over. While Wang Duoyu was in the restroom, Jiang Shoucheng got up and followed Li Damao and Mai Zili.
"I said Big Hairy Old Mac, you all don't understand, do you?"

“I didn’t understand, but I’m listening carefully. I think I don’t understand now, but I will definitely understand in the future.”

Mai Zili is very honest, but Li Damao is a bit pretentious.

"Actually, I didn't quite understand what he said, but Professor Wang was talking about the Langlands Program, which is actually the part that interests me the most. Because of Professor Wang, many students in our mathematics department are very interested in the Langlands Program."

"Many of my sophomores and juniors are experts in Langlands program research and have written many papers on the subject."

"I usually use my free time on weekends to read these papers. Anyway, if I spend the time now, I can understand the papers on the Langlands Program in our school's mathematics journals."

"Of course, the knowledge Professor Wang talked about today is still too new, so I really didn't understand it very well."

This guy really deserves a beating!

What do you mean you don’t quite understand?

Look how capable he is!

At this moment, they had arrived at the toilet door. Coincidentally, Wang Duoyu had just come out to urinate, and the three of them hurriedly greeted him excitedly.

Li Damao and the other two were extremely excited and nervous, just like die-hard fans meeting their idols, they were almost screaming.

Wang Duoyu looked at the three of them with a smile, responded briefly, and then suddenly asked with a malicious tone:

"Student, you just said you didn't understand much, which means you only understood part of it. How about you tell me what you understood?"

Hearing this, Jiang Shoucheng and Mai Zili immediately looked at Li Damao, but the latter's mind was blank.

Good guy, he was just pretending. He said he understood some of it, and he was not wrong, but if you asked him to speak, how could he say it?

Understanding part of it and speaking it out are two completely different things, not to mention that he didn't understand it completely.

Seeing the other party's dumbfounded look, Wang Duoyu did not continue to embarrass him. He just smiled and patted the other party's shoulder and said:

"Work hard, our Harbin Institute of Technology needs talents like you."

Just now, Wang Duoyu was about to say that classic saying: We in the East Factory need talents like you!
Fortunately, he took back the word "Dongchang".

Li Damao was wearing the school uniform of Harbin Institute of Technology, while Jiang Shoucheng and Mai Zili were both wearing ordinary project department uniforms, which were old styles.

This old style of work uniform is for the "exchange students" from Shanghai. Although it is not necessary to distinguish them, Harbin Institute of Technology has many project departments, such as the 101 project, which has a high level of confidentiality.

Therefore, it is very necessary to distinguish them as much as possible.

In other words, Wang Duoyu confirmed the identities of Li Damao and the other three with just a glance.

Although Li Damao was pretending, he was also proving the excellence of Harbin Institute of Technology. After all, Li Damao should have been classmates with Jiang Shoucheng and others. Now Li Damao has made great progress. It would be strange if Jiang Shoucheng and others were not envious.

After returning to the classroom, Wang Duoyu quickly started the communication session in the second half.

This time when asking questions, Wang Duoyu chose to let Zelmanov ask a question.

The question asked by the latter is about the Burnside problem, which is a famous problem in the history of the development of group theory.

This is the question raised by Burnside in 1902: Is a finitely generated group with a finite square index a finite group?

This problem is unexpectedly difficult and has played an important role in the development of group theory and algebra.

What Zelmanov mentioned was a small problem in the Burnside problem. Of course, he did not want Wang Duoyu to directly solve the entire Burnside problem. After all, this problem is very difficult.

"Okay, thank you very much, Professor Zelmanov. Please take a seat!"

Wang Duoyu smiled and gestured with his hand, then said:

“That’s a very good question, and we all know it.”

Upon hearing this, Li Damao and the others couldn't help but look at Zelmanov curiously. After all, not everyone's name could be remembered by Wang Duoyu, even though Wang Duoyu had a very good memory.

But in the past few mathematics exchanges, after hearing many classmates' questions, Wang Duoyu always addressed the classmate as this classmate instead of calling him by his name.

John Milnor, Shing-Tung Yau, Charles Fefferman and others also looked back at Zelmanov. They didn't know the latter before, but now they understand that anyone who can gain Wang Duoyu's respect must be no ordinary person.

After briefly describing the Burnside issue, Wang Duoyu continued:

"We all know that groups are a branch of algebra. If an operation called multiplication is defined on a set of elements G, and this operation satisfies the following four conditions: (1) for any f, g∈G, there must be fg∈G;"

“(2) For any f, g, h ∈ G, we have (fg) h = f (gh); (3) There is a unique e in G such that for any element f in G, we have ef = fe = f; (4) For any element f-1 in G, there is a unique f in G such that f-1f = ff-1 = e.”

"Then G is called a group. The structures of various groups, the properties of various group operations, and the applications of groups are the subjects of group theory. The Burnside problem is about the classification of finite simple groups."

Wang Duoyu was talking nonstop on the podium, while Jiang Shoucheng and Mai Zili in the audience could understand the basic definitions at the beginning, but they couldn't understand anything at all later on.

On the contrary, Charles Fefferman and the others all frowned as Wang Duoyu spoke.

It's clear that Wang Duoyu isn't answering Zelmanov's question, but rather raising a new one. As we all know, the Burnside problem is an important topic in the classification of finite simple groups. One of them is: Are there unsolvable finite groups of odd order?
In other words, are all non-Abelian simple groups of even order?
In his Theory of Finite-Order Groups, Burnside proved that all groups of order pq, where p, q are prime numbers and a, b ≥ 0, are solvable groups.

This was the most important early work on the classification of finite simple groups, showing that the order of a non-commutative finite simple group has at least three different prime factors.

In 255, American mathematicians Fite and Thompson published a -page paper titled "All odd-order groups are solvable" in the Pacific Journal of Mathematics, proving that all odd-order groups are solvable, and thus the Burnside problem was finally solved.

As a result, Thompson won the Fields Medal in 1970.

However, now that Wang Duoyu has gone deeper into the topic, Qiu Chengtong and others can hardly keep up with his thinking.

Currently on the blackboard, Wang Duoyu is addressing the Burnside problem: a finite generating group Gi＞, where each element is of finite order, is Gi＞ a finite group?
In fact, this issue has been verified in Thompson's paper.

However, when Wang Duoyu was answering Zelmanov's questions, he found that it was not that simple.

Because he had a vague idea in his mind: the answer to the question of whether Gi＞ is a finite group is not correct, but negative.

So he immediately started to deduce and solve this conjecture.

Although Wang Duoyu's research in algebra or in the field of group theory, a branch of mathematics, is not very in-depth.

But because he had started studying the Langlands program a few years ago, he had of course studied group theory, but he had not involved the classification of finite simple groups.

The Burnside problem is an important topic in the classification of finite simple groups. He only knew about this problem but had not studied it.

If Gi＞ is not a finite group, then Thompson's original complete proof of the Burnside problem had a fatal flaw.

The value of the Fields Medal in his hands is certainly declining.

On the podium, Wang Duoyu had already filled the entire blackboard with mathematical symbols.

Jiang Shoucheng and Mai Zili were both dumbfounded, and Li Damao was also stunned, because they couldn't understand it at all.

In fact, it was not just them who couldn't understand it. Even John Milnor, Shing-Tung Yau, and Gerd Faltings couldn't keep up with Wang Duoyu's thinking.

Half an hour later, Wang Duoyu suddenly stopped, staring at the blackboard and thinking silently for more than ten seconds. He turned to look at the people under the podium and said:
"Ladies and Gentlemen, the Burnside problem is about a finitely generated group Gi＞, where each element is of finite order. Is Gi＞ a finite group? The answer is no."

One stone caused a thousand waves!

The expressions of John Milnor and others in the audience suddenly became very rich.

Thompson's paper has been verified by the global mathematics community, so it cannot be false!

However, standing in front of them was Wang Duoyu, the recognized emperor of mathematics in the global mathematics community. He could not be wrong.

Depend on!
My scalp is tingling!
Qiu Chengtong was the first to stand up, walked up to the podium, and said to Wang Duoyu:

"Professor Wang, although I really hope you are right, how about you repeat the whole process?"

Upon hearing this, the latter shook his head and said:

"We don't have enough time today. I want to spend the next few days to carefully deduce it. I may need your help to review the paper, and then I want to publish it as soon as possible."

"At the same time, I think this problem will be a new one. I don't have any ideas on how to solve it yet. For now, let's stop here for today's sharing and discussion. I'm leaving now."

After saying that, Wang Duoyu turned and left.

Only Shing-Tung Yau was left standing there, disheveled in the wind.

John Milnor, Charles Fefferman, Andrew Wiles, Gerd Faltings and others in the audience all looked at each other in surprise. They had never expected that today's communication and sharing would go in this direction.

However, they did not leave, but stared at the blackboard and discussed seriously.

Zelmanov's expression was even more interesting. He didn't expect that he would be the first to stand up and ask a question, and then he asked a new question.

Wow, how come Wang Duoyu’s thinking logic works so fast?
However, the fact that he is recognized as the Emperor of Mathematics must be due to his own strengths.

The other young people in the back row, such as Li Damao and others, were all at a loss.

The exchange meeting was not even halfway through and ended in vain, but Wang Duoyu did only answer one question and asked another question himself.

The key is that he hasn't explained yet, which makes everyone anxious and upset.

You should know that Thompson had completely proved the Burnside problem more than ten years ago, and in 1970, the International Congress of Mathematicians also awarded him the Fields Medal.

At this time, Wang Duoyu said that the other party's paper was not valid. The Burnside problem of "a finite generating group Gi>, each element is of finite order, Gi> is a finite group" does not hold true!!!
Everyone was numb.

Who is more awesome, Wang Duoyu or mathematicians around the world?
Or were the mathematicians of the time just idiots who didn't think about the problem carefully and let Thompson get away with it?
Just thinking about one person fighting alone in the global mathematics community made Li Damao and others very excited.

However, we are not sure what the specific situation is at the moment, so let's wait and see.

Two days later, the news from Harbin Institute of Technology had spread among professors of mathematics departments at Peking University, Fudan University, Nankai University and other universities.

Mathematicians of the older generation, including Shiing-Shen Chern, Luogeng Hua, and Su Buqing, had different reactions. Some thought Wang Duoyu was too young and too stubborn.

Some people believe in him, after all, Wang Duoyu has never disappointed anyone.

He had previously published a paper proving the ABC conjecture, and soon after he proposed the conjecture, he proved it again.

Moreover, he published this paper directly without passing the review.

After it was published, many people criticized Wang Duoyu. Even John Stilwell, a mathematics professor at San Francisco University, criticized Wang Duoyu in the newspaper, calling him a clown who was seeking attention.

But what about now?
After the presentation of the paper proving the ABC conjecture last year, no one has been able to prove it wrong until now.

Everyone accepted this paper and confirmed that it was correct, rather than the illogical conclusion John Stilwell had said.

In addition to the older generation of mathematicians such as Hua Luogeng, Chen Jingrun, Lu Qikeng, Guan Zhaozhi, Zhang Guanghou and others were all waiting for Wang Duoyu's paper.

Because before they saw Wang Duoyu's paper, they could only stare blankly.

As for asking them to look through the paper in the Pacific Journal of Mathematics and verify whether Gi＞ in the Burnside problem in the paper is a finite group, that is giving them too much credit.

If they had the ability, it would not be their turn.

As time passed, Wang Duoyu's paper still hadn't been published, but back in the United States, mathematics professor John Stilwell published another article in the San Francisco Chronicle: "A clown from a great Eastern country wants to challenge the world's mathematicians? It's pure wishful thinking!"
John Stilwell didn't dare to mention Wang Duoyu's name directly because he had been slapped in the face by Wang Duoyu once before.

In fact, John Stilwell did not attend the report meeting last year. He just wanted to take advantage of the traffic because Wang Duoyu published the paper proving the ABC conjecture without passing the review, and the other party arrogantly stated that less than ten people in the world could understand the paper.

After all, he is not only a mathematics professor, but also a popular science writer of mathematics.

There's nothing wrong with selling your books, making some extra pocket money, and getting some traffic, right?
So to be honest, Wang Duoyu simply didn't bother to slap him in the face.

And the mainstream mathematical community had no intention of paying any attention to John Stilwell.

After all, everyone has to have some dignity, and certainly would not bother to deal with someone like John Stilwell who is not in the mainstream mathematics community.

There is no unemployed mathematician in the world. Some are developing in the field of pure theoretical mathematics, while others are working in the industry on the application of mathematics.

People like John Stilwell, who have half a foot in the field of pure theoretical mathematics and the other half in popularizing mathematics, are, to be honest, a bit low.

Anyway, top mathematicians rarely do this kind of thing.

Moreover, he is shameless and operates without any bottom line. This kind of person is the rotten apple.

Following John Stilwell's article, the global mathematics community knew what Wang Duoyu had been doing recently.

"You mean he's still writing his thesis? That's all spread out there."

Smale came to Harbin Institute of Technology from the United States. He did not meet Wang Duoyu because the latter was in seclusion writing a thesis.

So he could only find Shing-Tung Yau and ask about the details of that day.

Upon hearing this, the latter directly showed Smel the entire proof process written by Wang Duoyu on the blackboard.

However, Smale couldn't quite understand it. It wasn't that he hadn't studied group theory, but these processes were disjointed and very messy. How could he understand them?
Next, Smale briefly recounted to Shing-Tung Yau what he had learned in the United States.

In the American mathematics community, many mathematics professors reread the Pacific Journal of Mathematics because of Wang Duoyu's actions, and continued to deduce the problem mentioned by Wang Duoyu.

On the other hand, mathematicians engaged in group theory research in the United States have all stated that they have proved that the Burnside problem of 'a finite generating group Gi>, each element of which is of finite order, is Gi> a finite group' is valid and the answer is correct.

Therefore, several mathematics professors publicly asked Wang Duoyu questions in the media. If Wang Duoyu said that the answer to this question was no, then please produce a proof paper, otherwise, don't talk big.

After listening to this, Qiu Chengtong sighed:
"To be honest, I could imagine how much of a stir this incident would cause in the mathematics community, but I didn't expect it to get so out of hand."

Now, almost all mathematicians in the world know about this, right?
Perhaps those mathematicians who have turned to applied mathematics will not pay attention to this matter, but those pure theoretical mathematicians, especially those related to group theory research, will definitely dig deep and ask Wang Duoyu to explain it clearly.

This is because Wang Duoyu’s current status is very different, and his influence in the global mathematics community is unprecedented.

Therefore, since everyone finally caught Wang Duoyu doing something wrong, they naturally wanted him to admit it.

It’s impossible that all the mathematicians in the world are not as good as Wang Duoyu, right?

Definitely impossible!
So what is going on?

Even Shing-Tung Yau doesn't know now. After all, although his research directions are quite diverse, he has not done in-depth research in group theory. It is only because of Wang Duoyu that he has delved into the study of the geometric Langlands conjecture.

In the United States, Professor Shang Zhongmin packed up all the newspapers he had collected and put them on the plane.

A few days later, Shang Zhongmin, who came back to report on his work, met Liu Deben in the secretary's office.

When the latter saw him, he did not immediately ask about the situation of Huaxin and other companies in the United States, but instead asked anxiously:
"Professor Shang, I heard that Professor Wang is being targeted by everyone in the US. What's going on? Isn't it just about a paper? Why are so many people picking on him?"

Liu Deben was not a mathematician, but he was very clear about the importance of Wang Duoyu to Harbin Institute of Technology.

Shang Zhongmin heard this and took out the newspapers he brought back one by one, while explaining:

"Secretary, Professor Wang is indeed being criticized by many American mathematics professors because of the Burnside Problem. The most enthusiastic among them is Professor John Stilwell of San Francisco University."

"I don't know the details, but I heard that Professor Wang raised questions about the Burnside Problem when he was giving a talk in the Mathematics Department building half a month ago."

"However, based on Wang Duoyu's usual paper writing speed, it shouldn't take him more than a month. Besides, this should be a trivial problem, right? Half a month has already passed. Could it be that he still hasn't finished the paper?"

It's almost September now, and more than half a month has passed since that day. It should have been proven by now.

Liu Deben shook his head and said:

"I went to his office this morning, and he was still working on his proof. I saw his brow was furrowed, as if he hadn't fully proved it."

"Oh, what shall I do?"

It was not easy for him to directly tell Wang Duoyu that he was young and frivolous and asked him to act with caution. After all, Wang Duoyu was young, and although he could listen to advice, he was also a very proud and arrogant person. How could he listen to it easily?
When it comes to mathematical problems, Liu Deben and others are of no help at all. Even people like Qiu Chengtong are equally powerless.

"Then can we find someone else to help? Or talk to Commissioner Hua?"

After hearing Shang Zhongmin's question, Liu Deben was also at a loss. After consulting Hua Luogeng, a member of the academician, could this problem be solved?

At the gate of Harbin Institute of Technology, Jiang Shoucheng and Mai Zili reluctantly said goodbye to Li Damao.

Of course, the two of them were not reluctant to leave Li Damao, but were reluctant to leave Harbin Institute of Technology.

In just over a month at Harbin Institute of Technology, less than two months of summer vacation, they not only received a subsidy of 100 yuan, but more importantly, they also learned a lot of knowledge.

Especially the experience in the project department, which is impossible to have at Fudan University.

There is no harm without comparison. When they were at Fudan University, Jiang Shoucheng and his classmates would take time to read Jin Yong's novels, but at Harbin Institute of Technology, they would go to the library whenever they had time.

Either he went to the computer room to do theoretical research in physics, or he went to the library to read books.

Fudan University’s library also has many books, but the variety of books at Harbin Institute of Technology is richer. The key is that the computers in Harbin Institute of Technology’s library can also check for plagiarism in papers.

Not to mention anything else, just this point alone is really friendly to many senior students who are graduating and have to write papers.

Therefore, faced with Harbin Institute of Technology, which has so many resources, Jiang Shoucheng and Mai Zili are of course reluctant to leave.

"Da Mao, after Professor Wang finishes writing the paper, you must remember to write to me, no, call me."

Finally, Jiang Shoucheng said this to Li Damao, and the latter nodded repeatedly.

"Don't worry, although I'm usually very busy, I will pay close attention to this matter. Once there is any latest news, I will definitely call you immediately."

"Damn it, in three years, I will definitely be admitted to the graduate school of Harbin Institute of Technology."

"Haha, Lao Jiang, I'm really looking forward to it. I hope we can be classmates again, but I suggest you don't apply to the Department of Mathematics at Harbin Institute of Technology, because it's too difficult!"

Li Damao's suggestion is very pertinent and is not a joke.

In the first half of this year, the Graduate School of Harbin Institute of Technology recruited new students, and the Department of Mathematics originally planned to recruit 20 master's students.

Because Wang Duoyu does not recruit students, or in other words, he has already selected his own students and will not recruit students from outside.

But later, Wang Duoyu persuaded John Milnor and others to join the Ice City Institute for Advanced Study. Among them, David Bryant Mandelford and Shing-Tung Yau would all teach at Harbin Institute of Technology.

The Institute of Advanced Studies does not have any pressure from professorial tasks. It all depends on the researchers' own wishes. Whether or not to accept master's or doctoral students depends entirely on their own wishes.

Wang Duoyu won't force anyone, and it's even less likely that others will be forced.

So this is very simple.

After learning that Professor Bryant and his team were also recruiting students, the number of admissions to the Graduate School of Mathematics increased to thirty-five.

Even so, the total number of applicants was 2,387.

With so many people, how can we divide the money?
Most college students who fail to pass the postgraduate entrance examination do not just leave.

In order to keep this person, Liu Deben, Lu Gongliang and others tried their best: come to the project department, research institutes, corporate units, etc., and don't do mathematical theoretical research, but do mathematical applications.

Because of working on mathematical applications, it is possible to meet Wang Duoyu and attend his courses.

The competition is already so intense this year, and it is hard to imagine how difficult it will be next year, the year after, or even the year after that.

Even undergraduate students at Harbin Institute of Technology like Li Damao may have their requirements raised.

So if Jiang Shoucheng and Mai Zili want to apply for the Department of Mathematics at Harbin Institute of Technology, it will be a hundred thousand times more difficult than the Road to Shu.

"No, even if the road to Shu is difficult, I will still apply to your mathematics department. The best way is to become Professor Wang's student."

After hearing Jiang Shoucheng's words, Li Damao almost couldn't hold it in.

In the end he just gave a thumbs up: "You are awesome!"

Jiang Shoucheng and the other person boarded the train and left Ice City. At this time, Wang Duoyu was sitting in the office, leisurely looking at the scenery outside the window.
