Under Delin's introduction, Pang Xuelin and these big guys met again.

Some of these people have met in the real world, while others have met for the first time.

That night, Delinie held a cold dinner at a hotel near Princeton University to welcome Pang Xuelin.

After dinner, at the invitation of Deliney, Pang Xuelin and Deliney started to wander around Princeton.

Princeton is located between New York and Philadelphia, and is a unique town.

The town is located in the Delaware Plain in southwest of New Jersey, with an area of ​​about 7 square kilometers, bordering Lake Carnegie in the east and the Delaware River in the west.

The scenery in Princeton town is elegant, with green trees and clear rivers flow quietly around the town. Coupled with the rich cultural influence of Princeton University, this town has become a favored residence for the upper class in the United States.

As a world-class top institution, Princeton University has not many students, including about 4,600 undergraduates and about 1,800 graduate students. The teacher-student ratio in the school reached an astonishing 6:1.

During the undergraduate education stage, Princeton is unique in the world.

Especially in the field of mathematics, Princeton University and Princeton Institute of Advanced Studies jointly form the world-renowned center of mathematics research.

In the real world, when Pang Xuelin graduated from Jiangcheng University, his first choice was Delinie's graduate student. Unfortunately, this boss didn't like him. In desperation, Pang Xuelin had to go to UC to find Tao Zhexuan.

Although he came to Princeton later, he only passed by in a hurry every time he came, and never wandered in the streets of this town as enjoyably as today.

"Pang, your Fermat's conjecture proof paper is very clever. I have studied it less than ten times and found that some of the theoretical frameworks used in it are very interesting, a bit like the far Abelian geometry proposed by my supervisor, but it seems to be a step further. Have you considered further improving this theory?"

Delinie said as he walked.

Pang Xuelin smiled slightly and said, "Professor Delinie, are you talking about Ponzi geometry theory?"

"Ponzi geometry?" Delinie was stunned for a moment, turned his head to look at Pang Xuelin, and said in surprise, "Have you sorted out this theory?"

Pang Xuelin nodded and smiled, "It's indeed sorted out, and I'm going to talk about this theory at this report."

Delinie was stunned for a while before smiling and said, "Pang, I was a little worried, will you have problems at the report meeting due to external pressure? I didn't expect that you didn't care about the opinions of the outside world at all, and you actually wanted to tell your new theory at the report meeting..."

Pang Xuelin laughed and said, "Actually, as long as you understand the core concept of Ponzi geometry, you will naturally understand the proof logic of the Fermat conjecture. I am not a biased topic. Professor Delinje, what you said just now is right. My Ponzi geometry theory was indeed developed based on the far Abelian geometry. I have always wanted to meet Mr. Grothendieck and discuss my Ponzi geometry theory with him. Unfortunately, I heard that after Mr. Grothendieck retired from the University of Montpellier, he lived in seclusion in the Pyrenees and disappeared..."

Delinie frowned and said, "After the teacher retired, he really won't see a foreigner. Even if I want to see him, it will be difficult. But Pang, if you really sort out the Ponzi geometry theory, I can help you pass it to the teacher for a look. Maybe the teacher is interested in meeting you."

"real?"

Pang Xuelin's eyes lit up, and Delinie was a student of Grothendiek.

In the real world, Grothendieck passed away in 2014, and Pang Xuelin had no chance to meet him again.

If we could meet Grothendieck, the greatest mathematician of the 20th century, in the country teacher world and this pope in the field of algebraic geometry, might have gained unexpected results.

At least, Pang Xuelin may have the chance to see the manuscripts burned before Grothendieck's death.

Delinie said: "I am at least 80% sure that you are a genius boy who solved the Fermat's conjecture, and you are likely to be the youngest Fields Medal winner. The Ponzi geometry theory framework is grand, and the mentor will definitely be interested in you!"

Pang Xuelin said: "Professor Delinie, then I will sort out the theoretical data on Ponzi geometry for you as soon as possible. I will trouble you more at that time!"

Deliney smiled and said, "Okay, give me the information and I will arrange it for you as soon as possible."

...

In the next two days, under the arrangement of Delingne, Pang Xuelin visited Princeton University and Princeton Institute of Advanced Studies, and met many bigwigs in other professional fields.

Until the third day, on March 18, 1993, Pang Xuelin officially held a Fermat Conjecture academic presentation meeting in the Princeton University Auditorium.

This report will attract the attention of the global media.

In the past few days, Pang Xuelin's name has frequently appeared in major media around the world.

Whether the twenty-year-old really proved the Fermat conjecture has become the focus of debate.

The party who supports Pang Xuelin believes that since Pang Xuelin decided to hold a report meeting in Princeton, it means that he is 100% sure, otherwise he would not have to stand up and let the world's top mathematicians pick on it.

The opposing side believed that Pang Xuelin was only twenty years old and had never received professional academic training, and did not have the ability to solve such problems at all. He was just a puppet figure launched by the Chinese government.

All kinds of controversial information were flying all over the sky.

Therefore, on the day of the report, hundreds of media from around the world gathered Princeton.

After obtaining the approval of Pang Xuelin and Princeton University, the report meeting chartered reporters, and CNN even obtained the full broadcast permission.

At 8:30 in the morning, Pang Xuelin finished breakfast in the hotel, went back to the room to change his clothes, and then accompanied by Xie Yongxin, he went straight to the Princeton University Auditorium.

At the entrance of the auditorium, Delinie, as the master, is welcoming the arrival of mathematicians from all over the world.

David Bryant Manford, Charles Feverman, Daniel Quillen, William Thurston, Shing-Tung Chiu, Sen Chongwen...

Seeing the characters whose names were engraved in the history of mathematics in the 20th century appear at the report meeting one by one, even Xie Yongxin, who had been following Pang Xuelin, became a little excited.

Although he is the president of the Chinese Mathematical Society, his academic status in the international mathematics community is still far from these famous figures.

At about 9 a.m., after a lengthy speech by the presenter of the presentation, Pang Xuelin stepped onto the rostrum.

A burst of exclamation suddenly sounded from the audience.

Many mathematicians have met Pang Xuelin for the first time.

Although I had known for a long time that the Chinese who proved the Fermat conjecture was just over 20 years old, after really seeing Pang Xuelin's slightly tender face, these mathematicians truly felt the impact brought by young people.

"Hello everyone, I am Pang Xuelin. I am very happy to be able to communicate with my colleagues in Princeton today on the Fermat conjecture issue."

Pang Xuelin's tone was neither fast nor slow. He had experienced such a scene many times, without any feeling of nervousness.
