The three of them walked all the way, chatting all the way.

Mathematicians have a strange friendship, and it is easy for two people who have not known each other before to establish a good relationship because they have a common language on a proposition.

Pang Xuelin, Shinichi Mochizuki, and Perelman are in this state.

Before Pang Xuelin, Shinichi Mochizuki was the most authoritative geometry researcher in the world.

Ponzi geometry is a new theory based on far abelian geometry, so Pang Xuelin and Mochizuki Shinichi have a common topic.

Perelman is about the same.

After proving the Poincaré conjecture at the beginning of the 20000 years, this guy disappeared from the mathematical world for more than a decade, and has been working on solving the problem of the existence and smoothness of the N-S equation.

As a result, Pang Xuelin's latest paper gave him a new way of thinking about the existence and smoothness of the N-S equation.

Although I don't know if this road can be finally completed, the emergence of Ponzi geometry undoubtedly allowed Perelman to see the dawn of a thorough proof of the existence and smoothness of the N-S equation.

Shinichi Mochizuki and Perelman are the kind of people who are not good at words, but when it comes to math, they tend to talk a lot.

It only took one lunch time for Pang Xuelin to establish a good friendship with Shinichi Mochizuki and Perelman.

After eating, the three of them went back to rest.

In the afternoon, the report meeting was mainly based on answering questions.

Having experienced the tempering of the Martian world and the wandering earth world, Pang Xuelin has long been familiar with all aspects of Ponzi geometry, and it is not too easy to deal with it.

The next day, Pang Xuelin began to explain how to prove the ABC conjecture through Ponzi geometry.

With yesterday's foreshadowing, plus this conjecture proving process, it has been studied by the outside world for nearly a month.

Therefore, the whole proof process was explained quite smoothly, and even in the follow-up question session, the mathematicians at the meeting did not raise many questions, and the answers were very easy.

However, Pang Xuelin knows very well that the real test is still on the last day of this report meeting.

At present, the entire mathematical community, and even the entire academic circle, are most concerned about solving the problem of solving the analytical solution of nonlinear partial differential equations.

In the past few days, as his paper uploaded to arXiv began to ferment, major media around the world began to appear related news one after another.

Xinhua News Agency: "Dr. Pang Xuelin, a well-known young mathematician in China and a professor at Jiangcheng University, announced the relevant proof of Ponzi geometry theory and ABC conjecture to the mathematical community at the report meeting in Paris at the beginning of the month. Professor Pang Xuelin will present the proposition to the mathematical community in a lecture to be held in the auditorium of Jiangcheng University on December 23. ”

BBC: "After proving the BSD conjecture and the ABC conjecture, China's genius mathematicians continue to challenge the analytical solution of nonlinear partial differential equations that have plagued the mathematical community for many years. However, the academic community has spoken highly of the Ponzi geometry theory proposed by Pang Xuelin. Professor Andrew Wiles, a famous mathematician and provers of Fermat's theorem, said that the emergence of Ponzi geometry theory is equivalent to the establishment of algebraic geometry by Grothendieck in the twentieth century, and this theoretical framework is expected to solve many problems that plague the mathematical community, and is worth ten Fields Medals! ”

CNN: "The problem of the century is expected to be solved, and if the Ponzi scheme is true for solving the analytical solution of nonlinear partial differential equations, then the N-S equation, one of the seven problems of the millennium, is also expected to be solved......"

Asahi Shimbun: "The Son of the Dragon has once again shown a miracle, following the BSD conjecture and the ABC conjecture, and the problem of solving the analytical solution of nonlinear partial differential equations is expected to be solved. Nonlinear partial differential equations are of great importance in the academic world, and Shuji Kojima, a professor of theoretical physics at the University of Tokyo, said that if established, the program would promote progress in all fields of the natural sciences on a considerable scale......

December 23, 2019.

Early in the morning of the third day of the presentation.

Pang Xuelin and Qi Xin finished breakfast together in the restaurant, and when they came out of the restaurant, Pang Xuelin was ready to go back to the apartment to prepare for the report meeting, and Qi Xin went straight to the auditorium.

In this report meeting, Qi Xin, as one of the main staff members of the preparatory group, undertook a lot of work.

Every day is basically busy from morning to night.

Except for running together for breakfast every morning, the two didn't see each other the rest of the time.

Qi Xin shook his fist at Pang Xuelin and said, "Senior brother, today is the last day of the report meeting, come on!" ”

"Don't worry, no problem!"

Pang Xuelin smiled slightly, waved at Qi Xin, and turned around to return to the apartment.

Fortunately, with the experience of the last BSD conjecture report, this time, Jiangcheng University was not open to the public, and reporters were strictly restricted from entering the campus, so Pang Xuelin was not disturbed too much.

At best, when you walk on the road, you will be secretly taken a few photos by students passing by.

Back in the dormitory, Pang Xuelin took a shower, changed his clothes, and then checked his paper on his laptop again before closing the computer.

Subsequently, Pang Xuelin walked out of the dormitory and went directly to the Jiang University Auditorium.

Coming to the door of the auditorium, Xu Xincheng, president of Jiang University, and Liu Tingbo, president of the Academy, were waiting at the entrance of the auditorium as usual.

It's just that today, Xu Xincheng is surrounded by more old men who look like they are in their seventies, with thin faces and white hair.

The old man was wearing glasses and looked a little familiar, but Pang Xuelin couldn't remember who it was.

Seeing Pang Xuelin coming, Xu Xincheng stepped forward and introduced: "Professor Pang, let me introduce to you, this is Academician Tan Hao of the Chinese Academy of Sciences, and he came here today to attend your report meeting." ”

Pang Xuelin couldn't help but be taken aback, and hurriedly said, "Academician Tan, hello! ”

In the 80s of the last century, he was already an internationally renowned expert in chemistry and nanomaterials, and his main research fields were organic molecular crystal structures, molecular nanostructures and other fields, and he had participated in the formulation of the 863 Program.

But the key is not here, Academician Tan has a very high status in China's academic circles, once served as the vice minister of science and technology, and did not stop working after retirement, and turned to the role of the government's think tank in the field of science and technology, responsible for grasping China's overall science and technology planning, and has a strong voice in the academic community.

Is it just because such a representative figure in the Chinese academic circle attended his report just because he was interested in his work?

Pang Xuelin frowned.
