Fan Zhenhua has never talked to these teachers about Ning Xiao's first paper on the NS equation. This is also due to a number of considerations.

Although he is a reviewer, the paper has not yet been published, and Ning Xiao has not uploaded the paper to a pre-publication website such as ChinaXiv or arxiv, so as a reviewer, he has to respect the author, the Annals of Mathematics, and some rules in the academic community.

Why aren't villains likeable? It's mostly because there are too many words.

If he had read Ning Xiao's paper to these teachers and professors in advance, it would have been impossible to hide it, and it was estimated that it would have spread throughout the Chinese academic circles immediately.

The Navier Stokes equation is different from the hyper-cube sensitivity conjecture proved by Ning Xiao, and the problem has a far wider impact in the world than the sensitivity conjecture.

As the millennium problem of the Clay Institute's public reward, it is naturally more concerned by the academic community. Many of the advances in this equation have even won Fields Medals, so it is not too careful.

Of course, for the average teacher, it is extremely incredible to meet a student who can publish an article in the Annals of Mathematics before he is an undergraduate.

Especially as lecturers and professors at the School of Mathematics of Peking University, they even wonder if the editors of the "Annals of Mathematics" have changed their temperament, after all, without a letter of recommendation and a mentor that can be recognized by these foreigners, there is a high probability that the editors will not read those manuscripts at all......

Therefore, everyone is also extremely curious about Ning Xiao, a student. To be favored by the editors of the Annals of Mathematics, and to be so favored by Academician Fan, everyone believes that Ning Xiao is outstanding, but whether it is worth investing so many resources is doubtful.

People are indeed very handsome, but I don't know if knowledge is really worthy of the old academician to spend so much effort to coax?

After all, for Ning Xiao's refusal to come to Yanbei University and the fact that he must go to Yanbei Sports University, if everyone can accept it with a peaceful attitude, it is naturally impossible. When I think about it, there is a hint of not seeing everyone in the eyes.

For these scrutinizing eyes, Ning Xiao didn't show any emotion.

He wouldn't even have wanted to come to this meal if March hadn't told him to show his "I'm good" side and show his "I'm amazing" side to gain more favor and resources. After all, strictly speaking, he is a student of Beiti.

Fortunately, Fan Zhenhua knew Ning Xiao's character, and after Ning Xiao became familiar with everyone, he began to greet Ning Xiao's father and Ning Xiao, and then introduced the group of people who came from the Sports University to the teachers, and the atmosphere in the box began to warm up. Until everyone politely divided the seats.

Ning Xiao was pulled by Academician Fan to sit beside him, and on the other side sat Chen Yonggang, the president of the University. Next to them sat Ning Dad, Ning Xiao and Lu Chengcheng, and the others and the mathematics professors of Yanbei University sat on the other side one after another, and the big table in the box that could accommodate twenty people just sat down.

As soon as everyone sat down, someone smiled and asked Ning Xiao: "Classmate Ning, you are here, our Academician Fan can talk about you in front of us every day these days." I also read your paper, and I have a lot of ideas. What direction do you plan to focus on in the future? ”

The questioner was Professor Luo Yi from Yanbei Institute of Mathematics.

In fact, Luo Yi is one of the authorities in the direction of Chinese probability, and his main research directions are big data sampling and complex mathematical analysis, and he has cooperated with many large domestic Internet companies.

Naturally, this question also has some implications for teaching. Everyone has a rebellious mentality, let alone these professors. The more they learned about how much effort Fan Zhenhua had put into Ning Xiao, the more angry many professors became. It's not that I have many bad intentions, but I think this kid is a little ignorant.

Originally, you kid nodded, and you could come to Yanbei University to go to school, but now you have to go to the University to attend classes, of course, whether it is worth it is a question. And it's not that Fan Zhenhua thinks it's worth it, so he can convince everyone.

As soon as Luo Yi's question came out, all eyes fell on Ning Xiao.

Just waited for Ning Xiao to answer.

It is no exaggeration to say that the teachers sitting at half of the tables here cover almost all the frontier research fields of mathematics, and no matter what answer Ning Xiao gives, someone will take over the conversation to probe the bottom of this child.

Ning Xiao looked up at Professor Luo Yi, thought for a while, and then replied calmly: "My study direction is quite miscellaneous, but what I am studying recently is algorithms. The current mathematical aspects are the results of several sharp scattering of the three-dimensional cubic nonlinear Schrödinger equation, including the free nonlinear equation and the nonlinear equation with external potential, the proof of scattering below the mass/energy ground state threshold, and the working principle of scattering at the NLS threshold with repulsive potential. ”

In fact, if you have to be more truthful, Ning Xiao's words are not very accurate. Because this can't be regarded as the content of his recent research, it should be said that he is studying and researching in the afternoon.

The sharp scattering result of the three-dimensional cubic nonlinear Schrödinger equation is certainly not the specific content of the turbulence algorithm itself. But it's extremely ingenious anti-piracy to introduce design-related things. Protecting the source code in a purely mathematical way is an extremely meticulous task, and it is a great test of basic mathematical skills.

Of course, as soon as this sentence came out, the faces of the mathematics lecturers and professors on the table who were ready to inspect Ning Xiao also froze......

How so......

The Schrödinger equation itself is a very complex research direction. Specifically, the research work on the sharp scattering results of the three-dimensional cubic nonlinear Schrödinger equation can basically be applied for a sub-topic to do research.

Mathematics is a very broad concept.

Especially modern mathematics, once it involves a very subdivided field, it is really not something that ordinary people can teach.

There is a saying that interlacing is like separating mountains, and this sentence can even be applied to different fields of mathematical research.

Of course, if you have to ask questions, it's okay, but in case Ning Xiao's answer involves too many highly professional things, the professors also need to check the information and calculate carefully to know if it's right, and it will be very difficult to step down in this scenario.

Can't you come up with a nonlinear equation problem on the spot for Ning Xiao to solve?

"Ahem, classmate Ning Xiao, it seems that you mainly want to do research on partial differential equations in the future?" Luo Yi coughed dryly, hoping to forcibly change the topic, of course, he was not wrong to say so, after all, Schrödinger's equation is the same as the NS equation, which belongs to both mathematical physics equations and partial differential equations.

Then he saw Ning Xiao on the other side shook his head, and still calmly elaborated: "No, for now, I am more exposed to the mathematical structures and invariants related to various modular spaces generated in symplectic topology and gauge field theory. For example, the generalized Gromov-Witten theory, the decomposition of modular spaces and the calculation of invariants, the opening and closing chord duality, local mirror symmetry, and so on. ”
