The lecture lasted from 8:30 a.m. to 11:30 p.m., a short period of three hours, which was enough for Pang Xuelin to deconstruct and reorganize the essence of Ponzi geometry theory and present it to many mathematicians attending the meeting.

At the last Paris conference, Pang Xuelin only showed the outside world the board book of Ponzi geometric theoretical framework, and there were not many mathematicians who could keep up with him.

Even though more than half a month has passed now, there are still a few mathematicians in the mathematical community who can really understand that board book thoroughly.

Therefore, today's report meeting is more like a lecture than a lecture.

As Pang Xuelin gradually deconstructed the Ponzi geometric theory, many mathematicians attending the meeting showed expressions of sudden realization on their faces.

"I see! Professor Pang went so far as to explore the internal structure of prime numbers by combining the addition structure with the multiplicative structure through the P advance number......"

"After Far Abel Geometry was reorganized by Professor Pang, it felt like a new world had opened......

"Wonderful! It turns out that the key to cracking the ABC conjecture is actually here......"

……

In the audience, from time to time, some people made happy discussions.

It is the joy that springs from the bottom of the heart when you testify to the truth.

For Schultz, Shinichi Mochizuki, Perelman, and Styx, who have long had a thorough understanding of the theoretical framework of Far Abelian geometry, Pang Xuelin's report also gave them a lot of new inspiration and gave them a new understanding of this new discipline of mathematics.

"Professor Pang is such a genius, it is hard to imagine that he has built such a large and profound theoretical framework at such an age, and the maturity of this theory is far beyond my expectations. If I had to do it myself, it would have taken decades to refine the theory to this point, even if I had the right idea. I really don't know how Professor Pang did it. Just a few months ago, he proved the BSD conjecture. ”

Shinichi Mochizuki looked at Pang Xuelin's young face on the stage and muttered to himself.

Perelman said: "There are many such people in history, Gauss, Abel, Galois and even Grothendieck...... It's just that the theoretical framework of modern mathematics is becoming more and more consolidated, and it takes young scholars more than ten years to complete the basic courses in various fields of mathematics, let alone create a new theoretical system. There are indeed fewer and fewer geniuses like Pang! ”

Mochizuki nodded and said, "Grigory, have you finished reading Professor Pang's paper on the analytical solution of nonlinear partial differential equations?" ”

After the group arrived in Jiangcheng yesterday, they did not communicate much, and as soon as they arrived at the hotel, they returned to their rooms to study Pang Xuelin's new paper "A Method for Solving Analytical Solutions of Nonlinear Partial Differential Equations with Broad Significance".

The paper was more than 100 pages long, and it covered a lot of concepts.

Shinichi Mochizuki didn't study much on partial differential equations, and he struggled to read them, and he only read more than 50 pages until four o'clock in the morning last night.

Perelman said: "I've roughly skimmed through it, and I can't guarantee that there are no loopholes in the details of this paper, but in terms of overall thinking, I don't think it's a big problem!" ”

Mochizuki couldn't help but show a look of shock in his eyes, and said: "This method of finding the analytical solution of nonlinear partial differential equations is really as Professor Pang said, and he should deserve the title of Grothendieck in the 21st century!" ”

The two whispered as the speech on stage came to an end.

"Okay, let's talk about Ponzi geometry first, let's go to lunch first, and then rest in the hotel. At two o'clock in the afternoon, I will continue to answer your questions in the auditorium. ”

The audience was quiet for a while, and gradually became noisy.

Whoa—

I don't know where the applause began, and gradually, the applause swept through the auditorium.

After many people got up, they took off their hats to greet Pang Xuelin, and some people bowed to Pang Xuelin, as if they were performing a disciple salute.

Perelman and Mochizuki were together, and they originally wanted to go up to say hello to Pang Xuelin, but they didn't expect that as soon as Pang Xuelin stepped off the stage, many mathematicians surrounded him.

Perelman and Shinichi Mochizuki are not the kind of people who like to be troublesome, and seeing that Pang Xuelin couldn't get out of his body for a while, the two of them prepared to leave the auditorium with the flow of people and go to the hotel to eat first.

But he hadn't taken two steps when a voice came from behind him.

"Mr. Perelman, Mr. Shinichi Mochizuki, wait a minute!"

The two turned around and saw Pang Xuelin getting out of the crowd at some point and walking towards where the two were.

"Hello, Professor Pang!"

Shinichi Mochizuki smiled.

Perelman is not good at words, but at this time, a kind smile appeared on his face, and he nodded at Pang Xuelin.

Pang Xuelin stepped forward, shook hands with the two of them respectively, and said with a smile: "Professor Mochizuki, Mr. Perelman, hello!" I knew you were coming yesterday, and I originally wanted to go to the hotel to meet you, but I was busy writing my thesis some time ago, and I didn't finish it until yesterday morning. I was so tired yesterday that I slept at home for a day, and today I was lucky enough to meet the two of you. ”

Perelman said: "It should be our honor, Professor Pang, you spoke very well in the morning, and you inspired me a lot. ”

Pang Xuelin smiled and said: "I just share my understanding of Ponzi geometry with everyone, let's go to dinner first, talk while walking, how about it?" ”

"Good!"

Shinichi Mochizuki and Perelman naturally won't have any problems.

Mochizuki Shinichi: "Professor Pang, the paper you published yesterday on the general solution method for the analytical solution of nonlinear partial differential equations is really shocking, I haven't seen you mention this research before, how did you think of linking Ponzi geometry with the problem of solving nonlinear partial differential equations?" ”

For this kind of question, Pang Xuelin was prepared, he said: "In fact, the study of Ponzi geometry was thought of at the beginning to solve the problem of solving partial differential equations. When I was a master's student at UCLA, I once helped a materials science research team build a mathematical model, and it turned out that the mathematical model was a system of partial differential equations, which was very complex to calculate and the accuracy of the solution was not high. ”

"Then I wondered if I could find a universal way to solve systems of nonlinear partial differential equations. When I was a Ph.D., I began to establish the theory of Ponzi geometry based on far-abelian geometry. As a result, a month ago in Paris, Professor Schultz unexpectedly gave me an inspiration to realize that Ponzi geometry could also solve the problem of the ABC conjecture. So I spent the night proving the ABC conjecture using Ponzi geometry. It's just that there wasn't enough time for the Paris presentation, so I didn't come up with the theory of general analytical solutions to nonlinear partial differential equations......"
