Between 1979 and 2009, three Fields Medal winners, plus thousands of mathematicians, combined with the results of these results are the basic lemma of the complete Langlands program, which has not yet been fully solved. I don't know how long it will take to completely solve the Langlands Program.

Not to mention that Junxin began to sort out the questions and research methods related to the Langlands Program in his brain, and at this time, Princeton University was also in the exam week at the end of the semester.

The term exam week is not unique to China, but also exists in other countries. Take the United States, for example.

The exam week in the United States, like the exam week in China, is conducted in a certain week of longer or shorter periods, and those who pass the subject are awarded credits, and those who fail need to retake or retake until they pass.

The advent of exam week also means that Junxin is about to end his study life at Princeton University and is about to return to China to start a new career.

Exam week is a heavy mountain for other students, but for Junxin, it is nothing. When it comes to pressure, there is no place that can compare to China's college entrance examination. Those who have taken the Chinese college entrance examination will hardly be afraid of the pressure of exams elsewhere. What's more, Junxin has also participated in the JS college entrance examination, which is known as the most difficult province in the country, known as the hell-level difficulty.

However, what Junxin didn't care about was not because of this reason, but that the teachers of all his professional courses had already told him below that their courses had given Junxin full marks, and the teachers of other non-professional courses had also told him privately that their courses had also given Junxin a considerable score, so his credits had been completed on the basis of not taking the exam.

Not having to take the exam is a relief for Junxin. This meant that he did not need to devote a lot of energy to the exam, and thus had a lot more time to solve the problems of solving the problems in the Langlands program.

Of course, the exam week didn't have any impact on Junxin, at least he also taught a class of elective courses, and also arranged the relevant assessment content, in a responsible manner, in fact, he still had to take a period of time to deal with the matter of the elective students' papers, for Junxin, who really opened a course for the first time, this matter was not sloppy, so it still involved a lot of his energy.

According to the time point of Princeton University's dissertation defense, the final dissertation defense time is also half a month after the end of the exam week, so the time left for Junxin is not long, if it is for ordinary people, it will be very difficult to launch a breakthrough in the problem of Langlands' program in such a short period of time.

Although Junxin does not have to take the Princeton exam, he still has great expectations for the exam at Princeton University. Princeton University does not have a proctor for exams than most schools in the world, because there is no proctor for Princeton's exams.

When Junxin first entered Princeton University, although he had heard of this style of the University, he had never seen it after all, so in order to see it, Junxin specially participated in an open class that required an exam, and ran over to experience the examination system of the University.

In general, although the exam week has an impact on Junxin, it is not big, except that his girlfriend needs to go all out to prepare for the first most formal exam abroad and concentrate on revision, so that during this time, except for going to the library to study together, she is hardly seen. It was Junxin who had to give marks based on the elective papers because the elective papers had already been submitted. Some students even have to talk to them to prepare for a small on-site thesis defense.

The previous incident allowed Junxin to experience the situation she was in when Gu Mengxue was with her and herself, and she was in the process of going all out to do something. The latter thing directly made Junxin's already nervous time even more insufficient.

"Jun, which aspect is your paper about?" The day before exam week, Junxin had just come out of the biology lab and was found in his office by Professor Feverman, who was also in Professor Feverman's office.

"For some of the content of group theory and number theory, how did you find my advisor?" After getting along with these professors very well, Junxin sometimes shows a young man's out-of-the-box personality in front of them.

Professor Mirno said with a smile: "Actually, a long time ago, when Professor Faltins invited you to Princeton, we already regarded you as a scholar of the same level, so no one in Princeton should choose to be your mentor, they think this is a kind of disrespect to you." ”

Jun Xin shrugged his shoulders and said, "It's not that exaggerated, right?" It's just a simple thesis defense. ”

"If you knew the list of scholars who applied to participate in your defense this time, you wouldn't say that!" Professor Mirno smirked.

Things have to start with Junxin's additional qualification to defend his dissertation. There is no objection that Junxin can qualify for a Ph.D. in mathematics at Princeton University. Even if Junxin didn't defend any of his dissertations, they thought it would be appropriate for Princeton University to award him an additional Ph.D. in mathematics. It's just that when he was routinely asked to write a paper, Junxin solemnly agreed, which made Professor Yigan a little unsure of Junxin's idea, whether he thought he would really make a big news, or really just write a paper casually.

However, when they saw that Junxin had consulted a lot of materials and literature during this time, they also knew Junxin's thoughts, and he was ready to do a big job. This made the professors at Princeton very excited. One by one, they began to apply to join Junxin's dissertation defense meeting. They were looking forward to the thesis of this teenager, who was not yet twenty years old, but already had the top achievements in the field of mathematics.

This is also the fact that this group of professors was originally only a member of the dissertation defense committee, but now they are all worthy of their name as if they were beaten with chicken blood.

As soon as Professor Mirno, the dean of the School of Mathematics at the Institute for Advanced Study in Princeton, spread the news in the School of Mathematics, which was originally only in Princeton University, and suddenly spread to universities all over the United States.

After learning the news that Junxin had obtained the qualification for the graduation defense, Professor Chern Shiingshen, who is the president of the American Society of Applied Mathematics, and Professor Qiu Chengtong of Harvard University also became interested.

Then the news spread ten, ten, and hundreds, and one after another, scholars from various universities and research institutes put forward requests to participate in his dissertation defense meeting. At this moment, nearly half of the top mathematicians in the United States got together again because of Junxin.

However, as the initiator of Princeton University, it is inevitable that they will be a little weak at this time, because they still don't know whether Junxin's thesis is written casually, or whether they have really done a lot of research and seriously written a world-class paper.
