Fan Zhenhua has never discussed Ning Zhi's first paper on NS equations with these teachers. This is also due to various considerations.

Although he is a reviewer, the paper has not yet been published, and Ning Zi has not uploaded the paper to a pre-publication website such as aXiv or arxiv. As a reviewer, he must respect the author, the annual journal of mathematics, and the academic community.

Some rules.

Why are villains disliked? Mostly because they talk too much.

If he had read Ning Zi's thesis with these teachers and professors in advance, it would have been impossible to hide it, and it would have spread throughout the Chinese academic community immediately.

The Navier-Stokes equation is different from the hyperdimensional cube sensitivity conjecture problem proved by Ning Zi. This problem has a far wider influence in the world than the sensitivity conjecture.

As the Millennium Problem that is publicly offered by the Clay Institute, it has naturally attracted more attention from the academic community. Many advances in this equation have even won the Fields Medal, so it is not too much to be cautious.

Of course, for ordinary teachers, it is extremely incredible to meet a student who has published an article in the "Annual Review of Mathematics" before he has even entered an undergraduate degree.

Especially as lecturers and professors in the School of Mathematics at Peking University, they even doubted whether the editor of the "Annals of Mathematics" had changed his temper. After all, without letters of recommendation and mentors that could be recognized by these foreigners, there was a high probability that the editors would not read those manuscripts at all.

of……

Therefore, everyone is extremely curious about this student Ning Ji. To be favored by the editor of the Mathematics Annual and to be so favored by Academician Fan, everyone believes that Ning Ji is outstanding, but is it worth it?

Investing so many resources makes people suspicious.

He is indeed quite handsome, but I don't know if his knowledge is really worthy of the old academician spending so much time coaxing him?

After all, if everyone can accept the fact that Ning Jie refuses to come to Yanbei University and must go to Yanbei University of Physical Education with a calm mind, it is naturally impossible. When you think about it, there is nothing wrong with everyone.

The taste is visible in the eyes.

Ning Zi showed no emotion towards these scrutinizing glances.

Even if March hadn't told him to show off his edge and show off his "I'm awesome" side in order to gain more favor and resources, he wouldn't have even wanted to come to this meal. After all, strictly speaking, he

He is a student of Beijing Sports University.

Fortunately, Fan Zhenhua knew Ning Zi's character, and after letting Ning Zi become familiar with everyone, he started to say hello to Ning's father and Ning Xiao, and then introduced the group of people who came from the University of Physical Education to everyone.

Teacher, the atmosphere in the box began to become warm until everyone politely assigned seats.

Ning Zi was pulled by Academician Fan to sit next to him. On the other side sat Chen Yonggang, the president of the University of Physical Education. Next to him sat Ning's father, Ning Xiao and Lu Chengcheng, and the others sat next to him with the mathematics professors from Yanbei University.

The next time I sat on the other side, there was a large table in the box that could accommodate twenty people.

As soon as everyone sat down, someone smiled and asked Ning Jie: "Classmate Ning, you are finally here. Our Academician Fan has been talking about you in front of us every day these days. I have also read your paper.

, Very thoughtful. Which direction do you plan to focus on learning in the future?"

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

It is naturally not easy to get a professorship in a place like Yanbei University. In fact, Luo Yi is one of the authorities in the field of probability in China. His main research directions are big data sampling and complex mathematical analysis, and he has cooperated with many large-scale Internet companies in China.

All companies cooperate.

Naturally, this question also has some meaning to test teaching. Everyone has a rebellious mentality, not to mention these professors. The more they understand how much effort Fan Zhenhua has put in for Ning Zi, the more unhappy many professors feel. Not that there are many professors.

I have bad thoughts, mainly because I think this guy is a little ignorant.

Originally, you could come to Yanbei University with just a nod, but now everyone is required to go to the National Sports University to attend classes. Whether it is worth it is of course a question. And it is not Fan Zhenhua who can convince everyone if he thinks it is worth it.

As soon as Luo Yi asked this question, all eyes fell on Ning Zi.

Just waiting for Ning Zi to answer.

It is no exaggeration to say that the teachers sitting on half of the tables here cover almost most of the cutting-edge research fields of mathematics. No matter what answer Ning Zi gives, someone will pick up the conversation and find out the child's background.

Ning Zi raised his head and glanced at Professor Luo Yi, thought for a moment, and then replied calmly: "My study direction is relatively complex, but what I am currently studying is algorithms. The current mathematics content is about three-dimensional cubic nonlinearity.

Several sharp scattering results for the Schrödinger equation, including free nonlinear equations and nonlinear equations with external potentials, a proof of scattering below the mass/energy ground state threshold, and a working principle on NLS subthreshold scattering with repulsive potentials."

In fact, if we must be honest, Ning Zi's wording is not very accurate. Because this cannot be regarded as the content of his recent research, it should be said that it is the content he is studying and researching in the afternoon.

The sharp scattering results of the three-dimensional cubic nonlinear Schrödinger equation are of course not the specific content of the turbulence algorithm to implement its own function. But it is something related to the extremely sophisticated anti-piracy introduction design. It is extremely difficult to protect the source code in a pure mathematical way.

Meticulous work extremely tests basic mathematical skills.

Of course, as soon as these words came out, the expressions of the mathematics lecturers and professors at the table who were already ready to examine Ning Zi froze...

how to say……

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 subdivided topic for research.

Mathematics is a very broad concept.

Especially modern mathematics, once it involves a very specific field, it is really not something that ordinary people can take the test and teach.

There is a saying that every other line is like a mountain. This sentence can even be applied to different fields of mathematical research.

Of course, if you must ask questions, it's okay, but if Ning Zi's answer involves too many highly professional things, the professors will also need to check the information and make careful calculations to know whether it is correct or not. In this scenario, it will be very difficult to step down.

Already.

Why can't Ning Zi solve a nonlinear equation problem on the spot?

"Ahem, classmate Ning Ji, it seems that you mainly hope to do research on partial differential equations in the future?" Luo Yi coughed a few words, hoping to forcefully change the topic. Of course, he was right to say so. After all, the Schrödinger equation

Like the NS equation, it is a mathematical physics equation and a type of partial differential equation.

Then he saw Ning Zi opposite him and shook his head, still calmly explaining: "No, for now, I am more exposed to mathematical structures related to various moduli spaces produced in symplectic topology and gauge field theory.
