The Science Fiction World of Xueba

Under the introduction of Deligne, Pang Xuelin and the group of bigwigs got to know each other again.

Some of these people have met in the real world, and some are meeting for the first time.

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

After dinner, at the invitation of Deligne, Pang Xuelin and Deligne strolled around the small town of Princeton.

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

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

The small town of Princeton has elegant scenery, green trees, clear rivers flowing quietly around the town, coupled with the rich humanistic influence of Princeton University, making this town a favored residence of the upper class in the United States.

As a world-class top university, Princeton University has a small number of students, including about 4,600 undergraduates and 1,800 postgraduates. The ratio of teachers to students in the school has reached an astonishing 6:1.

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

Especially in the field of mathematics, Princeton University and the Princeton Institute for Advanced Study together constitute a world-renowned mathematics research center.

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

Although he came to Princeton later, every time he came, he just passed by in a hurry. He had never wandered the streets of this small town so much as he enjoys today.

"Pang, your paper on the proof of Fermat's conjecture is very ingenious. I have studied it no less than ten times, and found that some of the theoretical frameworks used in it are very interesting. It is a bit like the Far Abelian geometry proposed by my supervisor, but it seems to be more advanced. Have you considered further improving this theory?"

Deligne said as he walked.

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

"Ponzi geometry?" Deligne was stunned, turned to look at Pang Xuelin, and asked in surprise, "Have you already sorted out this theory?"

Pang Xuelin nodded and said with a smile: "It is indeed sorted out, and I plan to give a lecture on this theory at this report meeting."

Deligne was stunned for a while, then smiled and said: "Pang, I was a little worried that you might have problems at the report meeting due to external pressure. I want to tell you about your new theory at the report..."

Pang Xuelin laughed and said: "Actually, as long as you understand the core concept of Ponzi geometry, you can naturally understand the proof logic of Fermat's conjecture. I am not off topic. Professor Deligne, in fact, what you just said Yes, my Ponzi geometry theory is indeed developed on the basis of Far Abelian geometry. I have always wanted to meet Mr. Grothendieck and discuss my Ponzi geometry theory with him, but unfortunately, I heard that Monsieur Grothendieck, after retiring from the University of Montpellier, lived in seclusion in the Pyrenees without seeing any outsiders..."

Deligne frowned and said: "After the teacher retired, it is true that I don't see outsiders. Even I want to see him. It is also 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. Deligne was a student of Grothendieck.

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

If you can meet Grothendieck, the pope in the field of algebraic geometry and the greatest mathematician of the 20th century, in the world of rural teachers, maybe you will get something unexpected.

At least, Pang Xuelin might be able to see the manuscripts that Grothendieck burned before his death.

Deligne said: "I'm at least 80% sure that you are a young genius who solved Fermat's conjecture, and you are very likely to be the youngest Fields Medal winner. The framework of Ponzi's geometric theory is grand, The instructor must be interested in you!"

Pang Xuelin said: "Professor Deligne, then I will sort out the relevant theoretical materials of Ponzi geometry for you as soon as possible, and then I will trouble you a lot!"

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

...

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

Until the third day, March 18, 1993, Pang Xuelin officially held the Fermat Conjecture academic report in the auditorium of Princeton University.

The report attracted global media attention.

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 Fermat's conjecture has become the focus of debate.

Those who support Pang Xuelin believe that since Pang Xuelin decided to hold a report meeting in Princeton, it means that he is 100% sure, otherwise he does not need to stand up and challenge the world's top mathematicians.

The opposing side believes that Pang Xuelin is only 20 years old, has never received professional academic training, and has no ability to solve this kind of problem at all. He is just a puppet created by the Chinese government.

Information of all kinds of controversy is flying all over the sky.

Therefore, on the day of the report meeting, hundreds of media from all over the world were attracted to Princeton.

After obtaining the consent of Pang Xuelin and Princeton University, reporters were allowed to enter the report, and n even obtained the permission to record and broadcast the whole process.

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

At the entrance of the auditorium, Deligne, as the host, is welcoming mathematicians from all over the world.

David Bryant Manford, Charles Fefferman, Daniel Quillen, William Thurston, Shing Tong Yau, Shigefumi Mori...

Even Xie Yongxin, who has been by Pang Xuelin's side all the time, became a little excited when he saw people who had engraved their names in the history of mathematics in the 20th century appearing at the report meeting one by one.

Although he is the president of the Chinese Mathematical Society, there is still a certain gap between his academic status in the international mathematics community and these well-known figures.

At nine o'clock in the morning, after a lengthy speech by the host of the report, Pang Xuelin stepped onto the rostrum.

There was a burst of exclamation from the audience.

Many mathematicians met Pang Xuelin for the first time.

Although they knew for a long time that the Chinese who proved Fermat's conjecture had just turned 20 years old, but after seeing Pang Xuelin's immature face, these mathematicians really felt the impact brought by young people.

"Hi everyone, I'm Pang Xuelin, and I'm very glad to be able to communicate with you on the Fermat conjecture in Princeton today."

Pang Xuelin's tone was unhurried, he had experienced this kind of scene countless times, and he didn't feel nervous at all.

"Before the report starts, I would like to express my gratitude to Princeton University and Professor Deligne who have made various preparations for this report."
