Early the next morning, Pang Xuelin got up very early, went to the stadium with Qi Xin to run a few laps, ate breakfast, went back to the apartment to take a shower, changed into a more formal dress, and went straight to the Jiang Auditorium.

The briefing will last for three days.

On the first day, Pang Xuelin will mainly explain the relevant content of Ponzi geometry.

On the second day, the whole process of proving the ABC conjecture will be explained.

On the third day, it will be the turn of the explanation to solve the analytical solutions of the system of nonlinear partial differential equations.

In these three days, it basically condensed the essence of Pang Xuelin's decades in the dimensional world.

When they came to the door of the auditorium, Xu Xincheng, Liu Tingbo and others had been waiting at the door for a long time.

"Professor Pang, you've worked hard these past few days!"

Xu Xincheng and Liu Tingbo are both scholars, so they naturally understand how tiring the reports will be in the next three days.

"Professor Pang, you've worked hard for the next few days, you should be sure!"

Xu Xincheng and Liu Tingbo are both scholars, so they naturally understand how tiring the reports will be in the next three days.

In particular, in the question-and-answer session in the second half of the report meeting, there were tricky questions from various angles, and sometimes a slight problem in the way of thinking was enough to make a scholar unable to get off the stage.

Pang Xuelin smiled and said, "Principal Xu, don't worry, it's no problem." It's almost time, let's go inside! ”

"Okay, let's go!"

Enter the auditorium.

The auditorium was already packed with mathematicians from all over the world.

Seeing Pang Xuelin's figure appear in the auditorium, all eyes were suddenly focused on him.

In these eyes, there is heat, expectation, and hope......

Ponzi geometry has faintly opened the door to a whole new field of mathematics, and these scholars want to know what kind of scenery lies behind this door.

In this report meeting, Pang Xuelin will give a clear answer.

Pang Xuelin's face did not change, and he was already familiar with this kind of scene.

Along the way, there were quite a few new faces at this conference compared to the last meeting in Paris.

The most eye-catching are Shinichi Mochizuki and Perelman, who are sitting in the front row.

Pang Xuelin's eyes swept over the two of them, and then walked up to the podium unhurriedly, and said: "Distinguished guests, good morning, welcome to my report on Ponzi geometry, this report will be divided into three days, I will discuss with you on the theoretical framework of Ponzi geometry, the proof of the ABC conjecture and the solution of the analytical solution of nonlinear equations. Next, we will start the first part of this presentation, the elaboration of the theoretical framework of Ponzi geometry. ”

Pang Xuelin lit up the screen, and suddenly, on the projection screen, the relevant content of the Ponzi geometry paper appeared.

Pang Xuelin paused and continued: "Ponzi geometry, let's call it that, in my opinion, this is a new discipline based on the theoretical framework of Far Abelian geometry, which organically combines algebraic geometry, differential geometry, arithmetic geometry, number theory, partial differential equations and other sub-disciplines, and shows us the internal connection of these disciplines. If we use simple mathematical language, it is to consider how much information about the algebraic cluster itself can be given by the etale primitive group in algebraic geometry, and to what extent it can determine the isomorphism of the algebraic cluster......"

"Next, we will discuss the following aspects of Ponzi geometry."

……

"The first part, the absolute Galawa group of rational numbers, and the flattened elementary group of any algebraic cluster, which does not conform to the commutative law ab=ba, affects the properties of the corresponding algebraic structure......"

"Absolute Galohuaqun Gal (Q?? /Q) can act on all smooth algebraic curves, i.e. a polynomial with coefficients of algebraic numbers, and the absolute Galois group Gal (Q?? /Q) as a symmetry group of algebraic numbers, of course, can be indirectly acted on the bipartite map by the symmetry transformation of the coefficients......"

"In the Absolute Galoa Group Gal (Q?? /Q) The simplest nontrivial transformation is complex conjugation, that is, the imaginary unit i is replaced with ?? i. In the complex plane, complex conjugation is mirror symmetry along the real number axis, so it acts on the smooth algebraic curve, and the mirror symmetry of the smooth algebraic curve is obtained......"

……

In the second part, we will start with the most basic structure, p, into integers. p into an integer, i.e., the projection limit of (Z/P^nZ)n≥1 for the prime number p. ”

"Let's take an example, take p=7

...... 00000000000000000042

...... 30211045064302335342

...... 12450124501245012450

Then the above numbers are P into an integer, and each P into an integer can be seen as a string of numbers extending to infinity to the left high position. But they're not infinite, each of them is different, and it makes sense to write it this way. ”

……

"On p to an integer, addition and multiplication can be defined. They are calculated in the same way as the four operations that we are familiar with every day, starting from the low position and slowly carrying the calculation, like adding and multiplying that can never be done. Subtraction and division are also defined in this way. Each integer corresponds to a P to an integer, with an infinite number of zeros in front of the P's base expression of the integer, and the result is the same as the operation we are familiar with. ”

However, when a number is a fraction, it can still be a P into an integer. For example, 1/5 = 0.2, which is obviously not an integer. But it's a 7 decimal integer: 1/5 = ...... 5412541254125412。 Obviously, as long as a p into the integer x bit is not 0, then its reciprocal is also a p into an integer. It is very important to be able to find the reciprocal, which means that p into an integer, or in its generalized p, has a complete addition and multiplication structure......"

……

Pang Xuelin's voice was unhurried, echoing in the auditorium.

The whole auditorium felt like a university classroom.

Pang Xuelin is a professor who lectures on stage.

The mathematicians who attended the conference became loyal students.

Many people either take notes or type on their laptops at a rapid pace.

There are also people who exchange their opinions and opinions on Ponzi geometry in very low voices.

Liu Tingbo used a pen to write and draw in his notebook from time to time, and Xu Xincheng, the president of Jiang University, who was sitting next to him, looked confused.

After all, he is only a pharmacist, and this theory, which is difficult to understand even for professional mathematicians, is tantamount to a book from heaven to him.

"Lao Liu, Professor Pang has this theory, there is no problem, right?"

Although as early as when Ponzi geometry had just come out, the School of Mathematical Sciences of Jiangxi University specially convened people to study Pang Xuelin's theory and gave a positive answer.

But Xu Xincheng is still a little worried.

Liu Tingbo on the side said with a smile: "President Xu, don't worry, Professor Pang spoke very well, didn't you look at the performance of the people around you?" ”

Xu Xincheng looked around, and the vast majority of mathematicians present, like Liu Tingbo, were making notes, and they seemed to face this report meeting with a learning mentality.

There were also people talking to each other, discussing Ponzi geometry in low voices.

But there are almost no expressions of disdain or disapproval on their faces.

Xu Xincheng couldn't help but breathe a sigh of relief.
