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

172, Visiting Scholar Exchange Yang Mills Existence and Quality Gap Zhu Ling Gives Birth

November 15, 1980, University of Cambridge, Great Britain.

"Bonavent, come and take a look at this paper. I'm doomed." Severubk came to Bonaventura Pierce with a magazine on his face and said dejectedly.

Both of them were doctoral students in mathematics at Cambridge University, and Severubk's research topic was Fermat's conjecture.

As early as July this year, the two of them went to Princeton University to attend Wang Duoyu's lecture.

So they still remember the bet between Shing-Tung Yau and Duoyu Wang on who could prove Fermat's conjecture faster.

I never expected that Wang Duoyu’s paper has been published in November.

If Severubk had not seen the news and then asked someone to buy a copy of "HIT Mathematical Journal", he would not have known about this.

"Don't be so pessimistic. I told you in July to change your subject. You didn't want to. It's not too late now."

Bonaventura Pierce spoke to 'comfort' him, well, he was actually gloating.

Who made them have a good relationship?

Severus suddenly became even sadder. He didn't want to change the subject because he didn't want his efforts to go to waste.

Is it easy to write a paper?
Of course it is not easy. Not only do you need to look up information, but you also need to make progress and solve the problems in the thesis. This is mathematics, not liberal arts, so you can't just make up anything.

Writing his doctoral dissertation was even more challenging. One topic had already blocked his mind for nearly half a year. What could he do? He was also desperate.

It was at this moment that Augustine Leighton appeared before them.

"Severus, this is something you have to go through. Just like me, can't you just look at it with a more open mind? Don't be too ambitious and pursue those top-level topics. It's better to be down-to-earth and solve those small problems first."

Augustine Leighton's consolation did have some effect.

Because Augustin Leyden had been forced to change his thesis topic before. Who made Wang Duoyu, a mathematical genius from a big country in the East, so powerful?
Bonaventura: That makes sense!
On the other hand, Andrew Wiles, who had come from Cambridge University to the Institute for Advanced Study in Princeton as a researcher, soon learned about this matter, and his mind instantly became active.

why?
The reason is very simple. Wang Duoyu is an incredible person.

Andrew Wiles has read all the papers published by Wang Duoyu in the "Annals of Mathematics", and also asked someone to buy papers about Wang Duoyu from magazines such as "Science China·Mathematics" from China. When the "Harbin Institute of Technology Mathematical Journal" appeared, he ordered it as soon as it appeared.

Because he had corresponded with Robert Langlands, he learned from the latter that the "HIT Mathematical Journal" would publish Wang Duoyu's paper proving Fermat's conjecture.

From the earliest "Computer Approximate Solutions of Nonlinear Differential Equations" to "A Method for Finding Eigenvectors of Matrices on Distributive Lattices", to the four papers proving the Poincaré Conjecture, and to the current phased proof of the Fermat Conjecture.

Wang Duoyu's paper output is amazing, not only in large quantity but also in high quality.

In just over two years, he produced more than fifty high-quality papers.

So how did he do it?

Andrew Wiles, also a researcher in the field of mathematics, was puzzled.

When he was at Princeton University, he did not have the opportunity to communicate with Wang Duoyu face to face. Perhaps he should go to China instead of staying at Princeton University.

"What? You said you were going to Harbin Institute of Technology for a visiting scholar exchange?"

In the mathematics office of Princeton University, Andrew Wiles communicated with Zhu Chengwu, Jian Xianglan and others, hoping that the latter two could pass the message back to Harbin Institute of Technology.

After hearing this, Zhu Chengwu and Jian Xianglan were shocked and completely unable to understand.

They all understood the words Andrew Wiles said, even though it was a pure London accent, they could still understand it.

But when they were put together, they couldn't understand it.

Is this so-called visiting scholar exchange serious?

After all, the so-called visiting scholar exchange is definitely not that simple. It must be because Harbin Institute of Technology has something that Andrew Wiles wants to get, otherwise he would not take the initiative to mention going to Harbin Institute of Technology.

If Andrew Wiles has to go to Harbin Institute of Technology for a visiting scholar exchange, then what is the point of Zhu Chengwu and Jian Xianglan staying at Princeton University?
Soon, the news spread back to the country. Li Rui and Liu Deben didn't know about it yet, but Fang Lihe of the Seventh Ministry of Machine Building had already received the news.

Li Rui and Liu Deben immediately learned the news and told their leaders that they would definitely entertain the British mathematics experts from the United States.

Andrew Wiles is definitely not an ordinary person as he can become a researcher at the Institute for Advanced Study in Princeton.

In fact, this gentleman also had ideas about Fermat's conjecture, but he had not put them into action yet.

Fermat's conjecture, one of the world's three most difficult problems, has troubled the global mathematical community for hundreds of years, and no one has been able to prove it, so Andrew Wiles has never been in a hurry.

Now he really couldn't sit still.

Not only did he eagerly want to know whether Wang Duoyu had completely proved Fermat's conjecture, but he also wanted to communicate more with Wang Duoyu, perhaps he could also achieve something.

Those who share the same idea as Andrew Wiles include Robert Langlands, Borchers, Jean Bourgain and others. They are all mathematics PhDs or researchers from European and American countries, and they are a group of people with good abilities and talents.

In the teaching building of the Department of Computational Mathematics at Harbin Institute of Technology, when Wang Duoyu learned that Andrew Wiles and others were coming to Harbin Institute of Technology for a visiting scholar exchange, he suddenly opened his mouth in surprise. After recovering from his shock, he smiled and said:

"Principal, didn't Confucius say that it is a great pleasure to have friends coming from afar? Then let them come."

Upon hearing this, Liu Deben immediately responded with a smile:

"Okay, no problem, I'll arrange it right away."

But soon, Wang Duoyu suddenly thought of something and asked:

"By the way, Principal, when will they arrive? Oh, late December? Okay, by then Zhu Ling will definitely be..."

Zhu Ling confirmed that she was five weeks pregnant in April this year. Based on the pregnancy period at the end of February or the beginning of March, her due date would be early December.

So if Andrew Wiles and the others come over in late December, there won't be much of a problem.

Wang Duoyu did not take this matter to heart, nor did he care too much about it. However, he did not know that nearly thirty foreigners were about to come to China, with different purposes, but all because of his relationship.

Theodore Wagner, director of the U.S. Security Agency's Special Branch, concealed one thing from Brutus Fraker, that is, he sent the first team of the task force to China.

This team is the ace team of the special office. They took the opportunity to go to Harbin Institute of Technology during the visiting scholar exchange organized by Andrew Wiles and others.

Wang Duoyu was unaware of all this.

As time approaches the end of November, the number of copies of the international edition of "HIT Journal of Mathematics" sold has exceeded 1,300. As a top professional journal, selling 1,300 copies is already a great success.

It can even be said to be a little unbelievable.

But if this journal contains a paper by a top mathematician who is currently in the limelight, and this paper also involves the world's three top mathematical problems, then the buffs are almost stacked, and it is normal that it attracts so much attention.

South Africa, Europe, the Polar Bear Empire, the Garden City, Tokyo, Japan, the United States, Canada, South America, and almost all major countries and regions in the world have subscribed to the "HIT Mathematical Journal".

The paper proving the interim proof of Fermat's conjecture is definitely a major event for the global mathematics community, and it is even more eye-catching than the Poincaré conjecture.

It’s just because Fermat’s conjecture is so famous that it has troubled everyone for hundreds of years.

Wang Duoyu did not pay attention to the sales of "HIT Mathematical Journal" because its price was not much, only two dollars.

It is destined not to be like popular magazines, selling tens of thousands, hundreds of thousands, or even millions of copies.

Moreover, Wang Duoyu still had a lot of work to do at this time.

The first is the preparation work for the memory project.

Since the beginning of November, Harbin Institute of Technology has been recruiting a large number of researchers and has also transferred some personnel from other projects to build the framework.

By the end of November, the memory project had been completed and was now led by Zuo Yuhe, Xi Guangan and Cai Jiahang. Because there were many technologies that needed to be developed, the number of people on the project exceeded one hundred.

According to the storage medium, the memory is divided into semiconductor memory, magnetic memory and optical memory.

Among them, optical storage, also known as CD storage, is very cheap and easy to carry. It is currently under the charge of Niu Ruishan and his project team.

As for the two major media storages, semiconductor memory and magnetic memory, they can only be completed by Zuo Yuhe and his team.

However, developing memory is not that simple, as it involves many technologies, such as magnetoresistive random access memory, which is a non-volatile memory.

Because it writes and stores data through magnetic states, thus achieving non-volatile data storage, its characteristics are low power consumption in standby state, and it has the advantages of high speed, increased storage capacity and enhanced durability.

For computer memory, the larger the data storage capacity, the better; the faster the data reading speed, the better; the lower the power consumption, the better; and the more stable the data, the better.

The requirements are very high, but the ideal is full and the reality is skinny.

Therefore, Wang Duoyu attaches so much importance to this storage project, and this is also the main reason why a new storage project should be created in addition to the CD storage project.

The second is the paper writing work.

Yes, after Wang Duoyu sorted out his previous communication notes with bigwigs such as Yang Zhenning, he read a lot of information and prepared to start working on Yang-Mills theory.

The reason he didn't delve deeper into the Langlands idea wasn't because he didn't want to, but because he wanted a change of mind, that's all.

It is easy to get tired if you run wildly on a certain path for a long time without any big gains.

Why do many people who have won the Fields Medal rarely achieve outstanding achievements afterwards?
In addition to the change in mentality, there were also various celebratory parties, welcoming and seeing off guests, etc., which meant that he did not have much time to focus on scientific research.

Wang Duoyu has not won an award yet, but he has been booked for the Fields Medal in two years, making him more qualified than other candidates such as Shing-Tung Yau.

The Poincare-Wan Duoyu Theorem alone is enough to book him a Fields Medal, not to mention that he now has a paper on the interim proof of the Fermat Conjecture?
"Professor Yang introduced a new mathematical concept, the union of the special gauge field and momentum mv given by the non-Abelian symmetry group of the Yang-Mills equations."

I saw Wang Duoyu writing and thinking on the manuscript paper.

It must be said that Yang-Mills theory is very profound. Even though Wang Duoyu has understood and mastered this theory, it is still very difficult to decipher it.

Who made the Yang-Mills problem of existence and mass gap not just a mathematical problem?
It should be noted that the predictions based on the Yang-Mills equations and the wave-particle duality of matter can describe the objective existence of elementary particles, and use the objective existence or formed fields to specifically explain the real existence of the above new mathematical concepts.

De Broglie extended the relationship between the momentum and wavelength of a photon, P=h/λ, to all microscopic particles, pointing out that a moving particle with mass m and velocity v also has wave properties. The wavelength of this wave is equal to the ratio of Planck's constant h to the particle's momentum mv, that is, λ=h/mv.

This relationship is also known as the de Broglie formula.

In P=mv, when m is 0, mv is equal to 0, which means there is no momentum, thus confirming that the Yang-Mills gauge field equations have meaning in the case of massless particles.

The gauge field and momentum describe two different physical quantities, so the union of gauge field and momentum is adopted, and the objectively existing or formed electric and magnetic fields are used to prove the reality and feasibility of this new mathematical concept.

The physical theory alone consumed a great deal of Wang Duoyu's time and energy.

Therefore, solving the top mathematical problem of Yang-Mills existence and mass gap will be the most difficult problem Wang Duoyu has encountered since his rebirth.

Moreover, he only conducts relevant research in his spare time, so his thinking is intermittent, not continuous.

He is not Lu Jiaxi, who has to keep thinking about this problem and stay up late to solve it.

Wang Duoyu doesn't have that habit.

On the contrary, he prefers to change his mind, because most of his inspiration comes from analogy.

Therefore, he also had other things to follow up on, such as some technical guidance from Diao Pai Company, and staying in the handheld game console project office to guide the work of Yin Wenjie and others.

The most important task of the handheld game console project now is the software and hardware engineering of the "China Cube" game cartridge.

The software project was easy to handle. It was personally directed by Wang Duoyu, and Zhou Sitong, Zhao Jiawei, Fan Honggeng and others were responsible for programming to complete the overall system framework settings and other work.

In terms of hardware, we can only rely on advanced equipment from abroad.

This is not a big deal. Harbin Institute of Technology is rich now, and the Foreign Exchange Department will not block foreign exchange expenditures in this regard.

With the arrival of November 29th, Wang Duoyu left Ice City and flew to Beijing.

Zhu Ling's due date is within the next half month, and no one knows whether she will give birth earlier, so Wang Duoyu just came here early.

At No. 6 Xila Hutong, after Wang Duoyu returned home, he personally prepared dinner for Zhu Ling.

“I can’t eat anymore.”

There was a table full of delicious food, but Zhu Ling, with her big belly, didn't want to eat because she had already eaten two large bowls of rice. She ate two chicken legs alone.

"Eat some more. If you don't want to, the little one in your belly will also want to eat."

Fang Zhen couldn't help but persuade her, but Zhu Ling looked at Wang Duoyu pitifully.

The latter was a little confused. This was not the real Zhu Ling.

It is said that women are weak by nature, but strong when they become mothers.

But when it comes to Zhu Ling, it seems to be the opposite.

In the past, Zhu Ling would confront her mother directly. She was stubborn and would never give in.

But now, I don’t know if it’s because I haven’t seen Wang Duoyu for a while, or what the situation is, but now she is actually acting coquettishly with him.

How could that be possible in the past?
"Mom, Lingling should be full. There's no need to force her."

Seeing her son-in-law said this, Fang Zhen had no choice but to keep quiet.

In the next few days, Wang Duoyu stayed in Courtyard No. 6, Xila Hutong, doing homework at home during the day and occasionally going out to buy groceries or meals.

He is rich now, so he doesn't cook for Zhu Ling every day unless he feels like it.

After all, his time is very important. It is already very good that he can waste a little time to cook for Zhu Ling. It is impossible for him to cook for her every day.

In the blink of an eye, it was December 3rd. Wang Duoyu, who had not been anywhere, had someone visit him today.

"Professor Wang, why haven't you said anything since you came to the capital?"

Chen Jingrun, Tao Fangqi, Yang Le, Lu Qikeng, Guan Zhaozhi and others all came.

Wang Duoyu was very surprised to see these unexpected visitors. "I don't think I told anyone that I came to Beijing. How did you know? Please take a seat."

He came to the capital in secret and had already instructed Liu Deben and others not to leak the news to the outside world.

After all, he was here to take care of his wife and accompany her during childbirth, not to work.

There are many people in Beijing who want to communicate with him, and he must be very aware of this.

When he was still an unknown person, Wang Duoyu believed very much in what Zhang Ailing said: Become famous as early as possible!
But after becoming famous, Wang Duoyu wanted to keep quiet, so he began to believe the saying that people are afraid of fame and pigs are afraid of being fat.

At this time, he was afraid of being disturbed by Chen Jingrun and others, so he did not let the outside world know that he had come to Beijing.

But there is no impenetrable wall in the world.

Tao Fangqi was the first to explain:

"Duoyu, we didn't mean to disturb you. We just thought it was a rare opportunity for you to come to Beijing, and that you haven't participated in our mathematics exchange meeting for a while."

To be precise, Tao Fangqi can barely be considered Wang Duoyu's mentor.

But Wang Duoyu's status is no longer the same as before, which makes Tao Fangqi much more cautious when speaking.

"Professor Tao, I understand clearly. I'm just curious, haha."

Wang Duoyu forced a smile and said casually.

Since they were all here, Wang Duoyu certainly couldn't continue his research. As a result, Chen Jingrun had already seen the manuscript on his desk.

"Professor Wang, are you proving the existence of Yang-Mills and the mass gap? Hiss."

When everyone present heard Chen Jingrun's words, they took a deep breath.

Since this question was made public, many people have wanted to give it a try, but without exception, they have hit a wall.

Yang Zhenning won the Nobel Prize for his theory of parity non-conservation. Before that, he had collaborated with Mills to publish non-Abelian gauge field theory, which is the famous Yang-Mills equations.

Among them, the mathematical problem about Yang-Mills existence and mass gap was raised.

Although there is no Nobel Prize in mathematics, it doesn’t matter. If you can make a breakthrough, then it is reasonable to win a Fields Medal, right?

So many people wanted to give it a try. As Chinese people, Chen Jingrun, Yang Le, Guan Zhaozhi and others naturally paid close attention to this math problem.

Precisely because of their research, Chen Jingrun and others clearly understood the problem of Yang-Mills existence and mass gap, and how terrifying it was.

Even Yang Zhenning needed to collaborate with mathematician Robert Mills to complete the relevant proof, but Wang Duoyu took on this top-level problem alone?
Could it be that Wang Duoyu's accumulation of knowledge in physical theory is also terrifying?
Lu Qikeng suddenly asked:
"Professor Wang, have you really completed the proof of Fermat's conjecture?"

As soon as these words were spoken, the sound of inhalation was heard again in the room, and the pupils of Tao Fangqi and others trembled.

Everyone looked at Wang Duoyu in disbelief. How could there be such a talented person?

In fact, after reading the paper in the "Harbin Institute of Technology Mathematical Journal", especially Chen Jingrun, the reviewer, he became more clear that Wang Duoyu should have proved the Fermat conjecture.

But without Wang Duoyu's personal confirmation or seeing the paper, people actually don't quite believe it.

Even if you are a genius, there is a limit, right?

But judging from what they saw, it might be true.

Wang Duoyu was stunned for a moment, then nodded and admitted it helplessly.

Everyone present was smart, so even if he denied it, it would be useless.

After all, everyone has read his paper, and it is not just a guess. It is completely different from what Chen Xingshen did before.

Seeing that he had really proved Fermat's conjecture, Chen Jingrun and others immediately urged him to see the paper.

And they had long forgotten the purpose of their visit.

"My thesis is still at Harbin Institute of Technology. I didn't bring it here." Wang Duoyu said with a smile:

"But since you're already here, why don't we discuss the Yang-Mills existence and the mass gap?"

When everyone heard this, they almost rolled their eyes.

Half a day later, Chen Jingrun and his friends left. Even though Wang Duoyu invited them to stay for dinner, they insisted on leaving.

It was just false politeness, they could see it. Besides, Wang Duoyu and his wife were rarely together, and Chen Jingrun and others would not be so stupid as to stay and disturb the couple's world of two.

The next morning, mathematics professors from Tsinghua University and Peking University, including Duan Xuefu, Jiang Boju, and Zhao Fangxiong, all arrived.

They seemed to have made an appointment and came here together.

For a moment, the whole courtyard was bustling with activity.

The neighbors in Courtyard No. 6, Xila Hutong, all stared with their eyes wide open. Why did it suddenly become so lively?
Before Wang Duoyu came, there would be cars coming to their alley every few months.

As a result, yesterday and today, not only did a lot of cars come, but they were all big shots.

Wang Duoyu didn’t know whether he was a big shot or not. He only knew that he could never have peace.

In the afternoon, someone came to inform him that his wife was about to give birth and asked him to go to the Health Institute immediately.

The Institute of Health is nearby, and Union Hospital is also within two kilometers, both are very close.

"Dad, how did you get here so quickly?"

When Wang Duoyu arrived at the Health Research Institute, he didn't expect that Zhu Qizhen was already waiting at the door of the delivery room. However, he didn't see Fang Zhen, so he guessed she was inside.

Fang Zhen and Zhu Ling, mother and daughter, both work at the Institute of Health. Although Fang Zhen is not an obstetrician, that is her daughter, and she is also a doctor. In addition, they are all colleagues from the Institute of Health who help with the delivery, so it is normal for her to appear in the delivery room.

"I don't have classes this afternoon, so I'm reading in your mom's office."

Hearing what his father-in-law said, Wang Duoyu nodded.

If Zhu Qizhen came from Beijing Institute of Technology, it would take at least half an hour.

It takes less than ten minutes to walk from Xila Hutong to the Institute of Health because it is really close.

Ah!
It was unknown how long it had been before Zhu Ling's screams of pain were heard from the delivery room, which made Wang Duoyu and Zhu Qizheng, who were at the door, very worried.

They say giving birth is like walking through the gates of hell, and it’s true.

Perhaps this is one of the reasons why Zhu Ling is not willing to have children?

As time went by, Zhu Ling, who had been howling for nearly ten minutes, finally stopped.

After a while, the sound of a baby crying was heard in the delivery room. What's more, the baby was crying very loudly.

Wang Duoyu and the others were overjoyed. They had finally overcome the difficulties.

After a long time, a nurse came out holding a baby, and Fang Zhen was watching beside her.

"Duoyu, it's my son."

"Huh? I thought it was a daughter."

After hearing that it was his son, Wang Duoyu said with some disappointment.

To be honest, he does not favor boys over girls, nor does he have the idea of ​​favoring girls over boys.

When it comes to raising children, daughters are much easier than sons.

Most sons are naughty and mischievous, while daughters are more well-behaved and cute.

So Wang Duoyu likes daughters more than sons.

Others like boys, probably because there is a throne in their family that needs to be inherited.

"I'm going to see Lingling."

After saying that, Wang Duoyu entered the delivery room, but was driven out by the obstetrician inside because the room had not been cleaned yet.

Fang Zhen was at a loss for words about her son-in-law. Others preferred sons over daughters, but why did Wang Duoyu prefer daughters over sons?

Zhu Qizhen was looking at the little guy in his wife's arms with a smile. The little guy looked a bit like his mother, with a fairer skin, and not as wrinkled as other babies. He was very cute.

The eyes and nose look like Wang Duoyu. The cute baby with big eyes is naturally super adorable.

Wang Duoyu also held his son in his arms, and his father-in-law and mother-in-law also asked about naming.

"Let's call him Wang Junhong. Lingling and I have already chosen a few names. Since it's a son, let's give him this name."

In fact, according to the family generation, he should be of the Jian generation, and his name should be Wang Jianhong.

However, the Wang family no longer names their children according to this generation. For example, his eldest brother’s youngest son, Wang Xiangdong, should actually be named Wang Jiandong.

It’s because the Wang family has moved to Dahonggou Village and has not had any contact with their original ancestral home for many years.

In the past, family concepts were very strong, and many people would consider generations when naming their children.

But after the founding of the People's Republic of China, only the clan concept in the south was still so strong. In the north, it was no longer like this.

"That's a good name, Junhong. Smile, smile at grandma."

Fang Zhen was overjoyed and started shouting immediately.

And the little guy Wang Junhong actually smiled at his grandmother.

This healing smile made Fang Zhen even happier.

After teasing the little one for a while, Wang Duoyu and the others were finally able to enter the delivery room to see Zhu Ling.

Although Zhu Ling looked pale at this time, she was much better than before.

"Lingling, thank you for your hard work."

Wang Duoyu held her hand and said with heartache.

Zhu Ling shook her head slightly, indicating that she wanted to see the child.

Seeing that she still wanted to sit up by herself, Wang Duoyu was dumbfounded and hurriedly stopped her.

After giving birth, did she stop being a spoiled brat? Did she become stronger?

That night, Zhu Ling insisted on going home. Wang Duoyu was helpless. Fang Zhen and the old couple Zhu Qizhen couldn't persuade her, so Wang Duoyu could only ask someone to help borrow a cart and push her home.

Asking her to walk or take a car is definitely not an option.

It can only be a cart.

The neighbors in the yard were all very curious. When they learned that Zhu Ling had given birth, they all wanted to know whether it was a son or a daughter.

Most people in this era prefer boys to girls.

After learning that it was a son, many people were disappointed.

Since Wang Duoyu's family has a new son, they have nothing to gossip about.

It’s not that Wang Duoyu’s family is not thriving, but people’s minds are very complicated.

Regardless of what the neighbors thought, it was already very late when Wang Duoyu sent Zhu Ling and her son home and settled them down.

There is no milk powder in this era, but there is milk.

The most important thing right now is to induce lactation, but Wang Duoyu doesn’t need to worry about this because Fang Zhen is a doctor and she can handle it.

So he and his father-in-law just helped out, busying themselves with everything.

There are still rooms in the small courtyard. My father-in-law definitely can't go back to Beijing Industrial College tonight, so he stays in the courtyard.

It is a small courtyard with a total of five rooms. In addition to the study, master bedroom, living room and kitchen, there is also a guest bedroom.

What's more, there is a bed in the study itself, so people can live there.

At worst, my father-in-law and mother-in-law can just sleep in the guest bedroom. There will definitely be enough room for them.

The next morning, Zhu Ling was able to get out of bed and walk around. Although she only took two steps in the room, it did scare Wang Duoyu.

In the morning, Chen Shengshen, Wu Wenjun and others came over. They didn't know that Zhu Ling had given birth, so they didn't bring any gifts.

However, they quickly wrapped the red envelopes, sat in the study for more than half an hour, and then left in a hurry.

In fact, Wang Duoyu still had time to communicate with Chen Shengshen and others, because his mother-in-law stayed at home to help take care of Zhu Ling, and it was not entirely necessary for him to take care of his wife personally.

However, Chen Shiing-Shen and his men were not so shameless and did not choose the right time, so they had to retreat.

Two days later, Wang Duoyu took some time out and went to the Institute of Mathematics to meet with Chen Shiing-Shen and others.

Chen Shiing-Shen and his team had two goals: one was to communicate with Wang Duoyu, and the other was to invite him to Nankai University to participate in an exchange activity.

This is what happens after becoming famous. There are invitations to all kinds of activities, which completely disrupt the previous rhythm of scientific research.

Wang Duoyu politely declined and said:
"Professor Chen, I'm not afraid to tell you the truth. I actually completed the proof of Fermat's conjecture in October. The reason I didn't publish the two papers directly at that time was, firstly, I needed to double-check them, and secondly, I wanted to help the nascent "HIT Journal of Mathematics."

"From November to now, December, I have been sorting out some of my previous experiences and insights from exchanges at Princeton University and other universities, so I still need to complete my own research projects in the next period of time."

"If it's an exchange in Ice City, then I might go, but if not, I won't make the time. I've set a rule for myself to attend similar exchanges at most once every two weeks. If I go more often, it will affect my daily research."

His meaning was very clear. No external factors could affect his own scientific research projects, and his own affairs must be put first.

The second most important thing was his family matters, so he came to the capital in secret and did not let anyone know.

After all, he stayed in Courtyard No. 6, Xila Hutong, Beijing, and besides accompanying his family, he also completed his scientific research projects.

In the office of the Institute of Mathematics, after listening to this, Chen Shiing-Shen felt very regretful.

In fact, Chen Shiing-Shen could understand Wang Duoyu very well, and he knew that the latter was not perfunctory or making up excuses to put him off.

You should know that Wang Duoyu has published so many high-quality mathematical papers in such a short period of time. In addition to his own talent, self-discipline and keeping his original aspirations in mind are the most solid driving forces on his road to success.

"okay, I get it."

Chern nodded and said with a smile:

"Now that you've proven Fermat's conjecture, I wonder when you plan to publish your second, complete proof? Also, when do you plan to hold your next conference? Or are you planning to wait until the International Congress of Mathematicians in two years?"

It is almost 1981, and in June 1982, the International Congress of Mathematicians will be held.

According to the current situation, it is possible to publish the second paper on Fermat's conjecture only next year, and then wait for another half a year before holding a conference. In this case, it would be better to wait until the year after next.

But Wang Duoyu knew clearly that in 1982, Poland was forced to postpone the 19th International Congress of Mathematicians for a year due to political reasons, and it was not until 1983 that the 19th International Congress of Mathematicians would be held.

Therefore, he would definitely give a briefing in advance if necessary.

It is not yet certain whether other people have such needs, so he does not know how to answer Chen Xingshen's question.

why?
The reason is very simple. He held a lecture at Peking University in April last year, and another lecture at Princeton University in July this year.

If it is held again next year, then a report meeting will be held almost every year. Wang Duoyu, a new star in the mathematics world, is more awesome than many famous mathematics masters who have been famous for many years, and his appeal is also stronger.

Therefore, Wang Duoyu would definitely not bring up this matter on his own initiative. He would have to wait for other mathematical celebrities such as Princeton University to bring up this matter. Otherwise, there would be very few people who would come by then, and it would not just be a laughing stock.

"We'll talk about it later. The paper hasn't been published yet."

After hearing Wang Duoyu's words, Chen Shengshen and others nodded.

Ignoring this matter, everyone started talking about other things, which was the formal discussion.

Wang Duoyu spent the entire day at the Institute of Mathematics and had lunch in the office. He finally left at 6:50 in the evening.

There are many seminars in the Institute of Mathematics, and they all hope to communicate with Wang Duoyu. Although Chen Jingrun and others have been here a few days ago, many researchers have not been here yet.

Attending lectures, reports, etc. are far inferior to this closed-door seminar.

Many researchers and graduate students in mathematics institutes prefer this kind of seminar because only in this way can they truly communicate face to face.

In contrast, lectures are the exclusive domain of the big guys, and ordinary mathematics researchers or master's students can only be forced to accept the opinions of the big guys.

But similar to the several reports Wang Duoyu had given before, they were too high-end and not everyone could understand them.

"Why are you back so late today?"

In Courtyard No. 6, Xila Hutong, Zhu Ling asked with a smile.

Wang Duoyu squatted down, teased the little guy for a while, and replied:
"The professors at the Institute of Mathematics are all so enthusiastic."

He didn't come back for lunch, and someone from the Institute of Mathematics helped him call home. Zhu Ling knew about it.

But what she didn't know was how popular Wang Duoyu was in the Institute of Mathematics.

The couple chatted for a while, and then the father-in-law came back. The mother-in-law had already prepared the meal, so the family started to eat dinner.

"Duoyu, you've been in Beijing for nearly half a month. How will your school's projects be handled if you're away from school for such a long time?"

At the dinner table, father-in-law Zhu Qizhen suddenly asked about this matter.

Wang Duoyu arrived in Beijing on November 29th, and Zhu Ling gave birth to the little guy Wang Junhong on December 8th, so ten days have passed.

It will be half a month soon. If Wang Duoyu doesn't return to Harbin Institute of Technology, I'm afraid Yin Wenjie, Zhang Jikang, Niu Ruishan and others will go on strike.

"Don't worry, Dad. I've talked to them on the phone and nothing will be delayed." Wang Duoyu responded with a smile. At this moment, the phone at home suddenly rang.
