In fact, Junxin was indeed not assigned the task of reception, and President William and the professors of the school agreed that he should first carefully prepare the materials that needed to be explained next, and then be brought by the professors of Princeton in the evening cocktail party, so as to save a lot of time and get to know many seniors in the mathematical field.

Junxin naturally raised his hands in favor of such an arrangement, but this does not mean that he really does not need to go out to greet people. At least the arrival of Professor Cheng Siu-yuen, a famous mathematician from Hong Kong, Professor Yau Cheng-tung from Harvard University, and Professor Chern Shiing-shen, president of the American Mathematical Society, all went out to greet them with great respect. It's just that Junxin stands at the back every time, so no one knows that he is Junxin, the protagonist of this conference.

"Jun, according to the arrangement, you will follow Mr. Mirno in the evening, and Mr. Mirno will show you all the mathematicians present, and will briefly introduce you to everyone, remember?" After the last batch of professors from Canadian schools arrived, Professor William Thurston took Junxin aside and whispered.

"yes, I see!" Junxin nodded and said. Mr. John Milno is a true Princetonian. He spent his undergraduate, master's, and doctoral studies at Princeton University. Mirno was born in Orange, Jersey, USA. While an undergraduate at Princeton University, he participated in the Putnam Mathematical Competition in 1949 and 1950 and proved the Fary–Milnor theorem. After that, he entered graduate school at Princeton University, where he completed his thesis, "IsotopyofLinks." After receiving his Ph.D., he continued to work at Princeton.

In 1962, Mirno was awarded the Fields Medal for his work in the field of differential topology. He went on to receive the National Medal of Science (1967), the Leroy PSteele Prize (1982, 2004, 2011), and the Wolf Prize (1989). He is also the author of many excellent books. These books are popular, concise and rigorous.

In 2011, he received the Abel Prize for his "pioneering discoveries in topology, geometry, and algebra." In response, he told Scientist magazine, "Itfeelsverygood," and said that "a 6 a.m. call is always a surprise." ”

At Princeton, Mirno's status today is equivalent to that of Professor Andrew Wiles, who proved Fermat's theorem. And because of Professor Mirno's special status with Princeton, he can be called the head of the Princeton Department of Mathematics, although the current head of Princeton is actually Professor Charles Feverman.

After coming to Princeton, because of Junxin's outstanding achievements in mathematics and his status as a student at Princeton, he was loved by almost all professors in the Princeton Department of Mathematics and even all professors in the School of Mathematics of the Princeton Institute for Advanced Study, and Junxin had considerable academic contacts with them. Professor Mirno, of course, is no exception.

Although Junxin has studied a lot of things in mathematics, he basically focuses on the Langlands program, analytic number theory, harmonic analysis, algebraic geometry, differential geometry, differential equations, Riemannian geometry and topology, and has discussed related academic issues with almost all professors at Princeton University. Professor Milno's achievements are mainly in differential topology, K-theory and dynamical systems, and Junxin has naturally consulted Professor Milno for cutting-edge problems in these fields. Professor Mirno seemed to appreciate some of Junxin's insights, so the professor, who liked to dance and write, agreed to take Junxin to meet the visiting mathematicians.

"Jun, this is not like you!" Professor Mirno laughed and looked at Junxin, who was a little nervous, and said, "You weren't so nervous when you discussed the problem with me!" ”

"Professor, is that time to discuss a problem?" Junxin looked at Professor Mirno, who was smiling, a little speechless. Professor Mirno is a bit of a joker and likes to play tricks on people, which is notoriously common in Princeton. But this is Professor Mirno's nature, and it can be regarded as a method of his lively thinking, so everyone is not disgusted.

"Comeon, no problem, don't you just get to know a few more old men? Besides, there's only one Ars here who is older than me, and that's your roommate, I've heard that. Professor Mirno said with a big grin.

Junxin couldn't help but cry and laugh a little, his roommate Als Alfors and the first Fields Medal winner Als Alfors have the same name, this stalk has spread from students to professors, and even in some ways, Als's reputation is much louder among professors than Junxin's name.

This is also a reflection of a rivalry between Princeton's and Harvard's mathematics departments, which are actually slightly worse than Harvard's without the Institute for Advanced Study (IAS) participating in the competition. Of course, if you add the Institute for Advanced Study, Princeton is the complete explosion of Harvard University.

The study of mathematics in these two schools is also similar, and both advocate pure mathematical research without other factors. Princeton has been built on a consistent purpose, while Harvard University has been formed through more than 100 years of academic construction and pursuit.

The relationship between the two is both competitive and cooperative, but relatively speaking, the competition between the mathematics departments of two universities in the United States is often evenly matched. Princeton's backing to the Institute for Advanced Study gives it access to cutting-edge mathematical research and abundant teaching resources. Harvard University, on the other hand, has relied on more than 100 years of academic construction to form a strong scale and core competitiveness, coupled with the support of Harvard University itself, there has never been a saying that there is a winner or a loser between the two.

But seriously, in fact, it is Princeton who overpowers Harvard, the simplest example is that in France, people who come out of the École Normale Supérieure in Paris only look down on students from Princeton University, and despise those who graduate from Harvard. Of course, this is only for math students. The École Normale Supérieure is one of the best mathematics departments in France, which shows that the mathematics department of Princeton University is still slightly higher than that of Harvard University.

However, relatively speaking, the two are a pair of "sworn enemies" because of the competition in status, and they do not give in to each other. This also leads to the fact that the professors at Harvard are always the professors at Princeton, and in the same way, the professors at Princeton will also brush the professors at Harvard University whenever they have the opportunity. Unfortunately, Junxin's roommate, poor Mr. Als-Alforth, became a little bit of a flirtatation for the professors at Princeton University.

Poor Ars, unfortunately lying down with a gun.
