My name is Huang Tian, ​​what the hell is this "Heaven is dead" nonsense?

Chapter 42 It Will Explode
Feng Zechun was slightly surprised when he saw the thick stack of manuscripts. He took it and glanced at the titles.

"Study on the explosion phenomenon of supercritical defocusing nonlinear wave equation... You're still doing research after graduation?"

Feng Zechun said in surprise, "Looking at this stack of manuscripts, you must have put in a lot of effort."

Huang Tian said, "It was out of interest. I liked mathematics when I was an undergraduate, and I thought I would pursue a master's degree and then do research. But later, my family's financial pressure increased, so I had no choice but to find a job after graduation."

That job wasn't exactly unpleasant, just tedious and repetitive. Of course, the frequent overtime was also quite annoying. After a while, I started thinking about math again, realizing that I still couldn't let go of it. I wasn't entirely satisfied unless I tried to take this path..."

Upon hearing this, Feng Zechun was deeply moved, as if he were seeing the image of a scholar who was determined to pursue his studies and never gave up. He nodded repeatedly in approval:
"Your dedication to learning is rare these days. Nowadays, students are lucky if they can just honestly complete the tasks I assign. Back in my day, every single one of my classmates studied like crazy, working themselves to the bone. You can't learn anything real without going all out..."

He reminisced for a while, then suddenly slapped his forehead and said embarrassedly, "When you get old, you just like to reminisce."

As he took a cleaning cloth from the glasses case on the glass table next to him and wiped his reading glasses, he asked, "Huang Tian, ​​can you tell me about the results and innovative points of your paper?"

Without hesitation, Huang Tian said, "Based on my calculations, I have come to the conclusion that the supercritical nonlinear defocusing wave equation will exhibit an explosion phenomenon!"

If you throw a pebble into a calm lake, it will create ripples that spread outwards, and the energy will also spread outwards, eventually returning to calm. We can call the process of energy gathering "focusing" and the process of energy releasing "defocusing".

The mathematical equations that study the former are called focused equations. For this type of equation, its solution will become infinite at a certain moment. At this time, we call it "explosion" because the energy is concentrated at one point and explodes with a bang.

Huang Tian's article studies the defocus equation. Generally speaking, the mathematical community agrees that the defocus equation will not explode because it represents the release of energy in all directions. Since it is a release, one can intuitively conclude that it cannot explode, and its solution should always exist and be good.

However, Huang Tian broke the academic consensus of the past few decades by proving with mathematical formulas that it would explode!

Sure enough, upon hearing Huang Tian's words, Feng Zechun was immediately startled, "You mean, it can explode?!"

Huang Tian nodded: "Yes, if mathematics doesn't lie to us."

Feng Zechun quickly asked, "What are your methods and tools?"

Huang Tian calmly said, "When we usually study defocus equations, we usually focus on the real solutions, since how can an outward force possibly explode?"

However, I tried a complex numerical solution, which led to special phases and oscillation modes. I found that when the phase and oscillations change, they generate complex interactions, which in turn cause energy to focus and cause an explosion.

The core of the entire paper is the introduction of the relativistic Euler equations, transforming the wave equation into a fluid dynamics problem.

Feng Zechun's eyes widened: "You introduced the Euler equations of relativism?"

"Yes, during the research process, I discovered a self-similar implosion solution in the relativistic Euler equations, and then I found a similar self-similar structure in the defocus equations. So I tried to do a structure transfer, mapping the former to the framework of the latter, and successfully turning the latter into a fluid dynamics problem."

Feng Zechun frowned deeply, muttering to himself, "Self-similarity, complex-valued solution..."

At one moment, he suddenly looked up, his cloudy eyes shining brightly as he stared at Huang Tian with delight. “Although I haven’t read your paper carefully yet and I’m not sure if your results are correct, your approach is extremely novel! The transfer of the Euler equations of relativism is simply a genius idea!”

Huang Tian smiled, showing neither arrogance nor humility. Feng Zechun said enthusiastically, "I need to take a good look at your paper, but I have a long lecture in half an hour..."

He took out his phone from his pocket, found the number of Xu Kaizhi, the dean of the School of Mathematical Sciences, and dialed it.

A few seconds later, the call was answered, and a deep, resonant voice came through, "Hey, Lao Feng, what's up with calling me all of a sudden?"

Feng Zechun said succinctly, "I have some good stuff here. Come and take a look. I'll be waiting for you in the lounge on the fifth floor of the Life Building. Also, help me find a substitute teacher. I won't be teaching the next class."

"Good stuff? You've encountered a paper you're unsure about?" Xu Kaizhi immediately realized.

"Yes, yes, you've come to the right place. It's hard to explain over the phone."

"Okay, wait a few minutes, I'll arrange a substitute teacher for you first."

After hanging up the phone, Feng Zechun waited for Xu Kaizhi to arrive, so he didn't rush to look at the paper. Instead, he chatted with Huang Tian, ​​his kindness and friendliness almost overflowing.

A short while later, Xu Kaizhi, wearing a gray jacket, appeared outside the lounge. He was in his fifties, with most of his hair still black, a square face, a thin build, and a very energetic appearance.

"Old Feng, what great paper is it that made you call me over in such a hurry?"

Xu Kaizhi walked into the house with a smile, and was taken aback when he saw Huang Tian. "And who is this?"

Feng Zechun proudly introduced, "My former student, Huang Tian, ​​the paper I want you to see was written by him!"

“Dean,” Huang Tian said. He knew Xu Kaizhi, who had been appointed dean of the School of Mathematics by Changda University when Huang Tian was a junior, and had been there for several years.

Xu Kaizhi asked in surprise, "Is he a student from our school? The young man has a very respectable appearance, like someone who's into academics. What level of doctorate are you doing now?"

Feng Zechun: "He graduated with his bachelor's degree last June."

Xu Kaizhi was surprised: "Undergraduate degree?"

How could an undergraduate graduate write a thesis that even Feng Zechun was unsure about?
Feng Zechun nodded, "Let me tell you, we really misjudged his talent back then. Huang Tian's mathematical intuition and insight are absolutely top-notch..."

He gave a brief overview of Huang Tian's novel ideas in the paper, and Xu Kaizhi's eyes grew brighter as he listened. Finally, he took a deep breath and said, "It is indeed a brilliant idea. If it proves to be correct in the end, this will definitely be a top-tier paper..."

The four top journals in the mathematics field are the *Annals of Mathematics*, *Recent Advances in Mathematics*, *Acta Mathematica Sinica*, and *Journal of the American Mathematical Society*. Of course, there are often a fifth or even a sixth journal among these four, but that's another story altogether.

Being able to publish a single paper in one of the four major academic institutions is enough to make you feel powerful in most parts of academia, at least at Changda University, because Changda might not be able to publish a single paper in ten years...
