"Let's go to the schools of the Ivy League first!" Professor Mirno walked into the hall with Junxin and swept it casually, then quickly analyzed the standing situation of each small group, and then turned around and whispered to Junxin.

In academia, this is already the norm. Once you hold a party, you can get together at the party, either with people who are in the same or similar direction to your academic research, or people from the same school.

This party was no exception. However, looking at the situation at the scene, the people who got together were basically school-based. However, it is no wonder that the transportation in the United States is relatively developed, and the popularization of communication equipment is far greater than in China, so what new research results can be discussed by telephone or directly face-to-face, and there is no need to get together to discuss, which also causes everyone to gather more in schools or research institutes.

In the Ivy League, except for Dartmouth College, which only has one Georgia professor, other universities such as Harvard University, Yale University, Columbia University, University of Pennsylvania, Brown University, etc., all came in groups, and Yale, which has the smallest number of students from each school, also has more than a dozen professors.

"Professor Mirnor!" By the time Professor Mirno stepped forward, the group stood up and greeted Professor Mirno.

"You're welcome, I'm just here to see you, and by the way, I'll introduce you to a peer who is relatively unfamiliar to everyone!" Mirno said, straightening his face.

"Oh?" It was Professor Yau Chengtong who answered, "Is this the little friend behind you?" ”

Yau Chengtong noticed this Eastern face Junxin very early, although he didn't know him, but it was a very good thing for him to see a fellow of the East face in Princeton. However, when greeting him, because there were too many people, Professor Yau Chengtong did not come forward to say hello.

"yes!" Professor Mirno nodded at Yau Chengtong and said, "He is exactly what I want to introduce to you!" ”

"Oh?" With the exception of the professor at Princeton University, everyone else looked interested.

"This is an exchange student from Shuimu University in Beijing, China, just a sophomore this year, his name is Junxin!" Professor Mirno said in a deep voice.

The professors, who originally thought that it was Professor Mirno who were leading the way forward, suddenly fell dumb and looked at each other one by one. After hearing the name, they didn't think that Professor Mirnor was promoting Junxin. In fact, in the current mathematical community, especially in the field of algebraic geometry and analytic number theory, Junxin is not a household name, but at least a great name. The paper proving the Modell conjecture was repeatedly studied and interpreted by professors at these schools. Later, in the new annual issue of the Annals of Mathematics in 81, the mathematical connection between Fermat's theorem and the Taniyama-Shimura conjecture was given, which was recognized by the mathematical community as Junxin's inference.

At the beginning of this year, another article on the estimation of sufficient conditions for the twin prime conjecture proved that Junxin's name is already the most dazzling new star in the field of analytic number theory.

But it's a pity that almost no one has heard of Junxin's name before, and almost no one knows what Junxin looks like, how old he is, and some basic information about his workplace and so on. Therefore, most people can only imagine an imaginary Jun Xinlai.

Although the imagination is different, most people think that Junxin should be a middle-aged man about 30 years old, and even Professor Chern Shiingshen, who has corresponded with Junxin, thinks that Junxin is a college student who has returned to the city from the countryside, at least in his thirties.

"Hello professors, my name is Junxin, and I'm from Mizuki University!" Junxin said very plainly, the problem of age is not the first time he has encountered it, the last time he participated in the International Union of Crystallography, he encountered this kind of thing, and he was very indifferent to the surprised and incredible eyes of everyone, and seemed to be used to such an atmosphere.

"God, I'm so young!"

"I can't believe it!"

"What an incomprehensible fact!"

……

After Junxin introduced himself, the crowd here suddenly seemed to explode, and one by one shouted loudly in disbelief, looking straight at Junxin.

"It's terrifying!" Among the many compliments, a Chinese sentence with a local dialect of Guangdong caught Junxin's attention, and looking in the direction of his speech, it was Professor Yau Chengtong who said with admiration.

Jun Xin nodded to Professor Yau Chengtong, and then quietly followed behind Professor Mirno without speaking, quietly looking at the group of professors in the mathematics department of the Ivy League of Eight Schools.

"Uh-huh!" Professor Mirno smirked and said, "Alright, alright,... You've seen the protagonist of the academic report, don't make such a fuss, okay? Then he turned to Junxin and said, "Let me introduce you, this is Professor Michael Jones from Yale University, he and I have the same research direction, both in the direction of K theory, but he has a deep knowledge of differential geometry; This is a ...... from Columbia University."

With the introduction of Professor Mirno one by one, these professors who enjoy a high reputation in the mathematical community and have high mathematical achievements at present or in the future were quickly recognized by Junxin, and correspondingly, Junxin's name, his age and various aspects of the situation were also known to these mathematicians who attended the meeting.

After the last professor finished his introduction, Professor Mirno smiled and said to Junxin: "Jun, I have suffered a lot of losses by introducing these mathematicians to you today, how about it?" How do you want to compensate me? ”

Jun Xin naturally knew that this was Professor Mirno's joke, but Jun Xin still thought about it seriously and said: "Recently, when I communicated with Professor Thurston, I had some ideas about the Poincaré conjecture, and I read some of Professor Donaldson's results on topology in the library, and I thought it was very interesting. This gave me some idea of the four-dimensional Poincaré conjecture, and I thought that if I could communicate with them fully these days, maybe I would be able to prove the four-dimensional Poincaré conjecture with great confidence. What do you think? If I prove this problem, will it be considered compensation to you? ”

Junxin's remarks include a popular topic in Princeton's mathematical community, the famous Greek topologist Papachlac Pros, winner of the 1964 Veblen Prize. Because his name is so long and hard to pronounce, everyone calls him "Papa". Until 1948, Papa kept his distance from the math community until he was invited to be a guest at Princeton University. Papa is famous for proving the famous "Dean's Lemma", for which the mathematician John Milno, who was fond of dancing and writing, once wrote a limerick: "The ruthless and unrighteous Dean's lemma / The natural enemy of every topologist / Until Papach Lakplas / proved it effortlessly." ”

However, the clever Greek topologist eventually succumbed to the proof of Poincaré's conjecture. There is a story circulating at Princeton University. Until his death in 1976, Papa was still trying to prove the Poincaré conjecture, and on his deathbed, he handed over a thick stack of manuscripts to a mathematician friend, who, after only a few pages, discovered the error, but chose not to say a word in order to allow Papa to pass away quietly.

There are even rumors from those who don't know that that friend is Professor John Milno. Although Junxin knew that it was not him, it was also evident from here that Papa had a great relationship with Mirno.
