"Jun, I heard that you wrote a book recently? I've heard Professor Mirno mention that he has a very high opinion of your book, how about it, can you show it to me? After the topic gradually shifted to academics, Shi Wanxiong and the other three sat quietly next to listen to the discussion between Junxin and Professor Yau Chengtong, and when they finished a question about the presentation class, Professor Yau Chengtong suddenly asked.

Jun Xin was stunned for a moment, then nodded with a smile and said: "There is such a thing, it is a summary of my discussions on various branches and major problems of mathematics since the twentieth century written when I was at Mizuki University, and on this basis, I have a discussion and idea on the development of mathematics in the next twenty years. ”

"Did you bring them with you?" Qiu Chengtong couldn't wait to ask.

Jun Xin nodded and said, "Naturally, how dare I not bring it here?" There's a lot of stuff in it that I'm not thinking about, and I need a math master like you to correct it! ”

"Hehe, Professor Mirno's opinion of your book is very high, and I don't think it's going to be any worse," Professor Yau said indifferently.

Junxin shrugged his shoulders, and then took out the "Mizuki-Princeton Guide to Mathematics" from his school bag, which was the first set of books Junxin got from the editorial department of Princeton University Press, and it was also a sample journal. Sent to Junxin here to let him check the typesetting problem. However, after reading it, Junxin didn't find any problems, so he put it in his schoolbag and brought it to Massachusetts.

"Professor Qiu, you don't have to be in such a hurry to read this book, I guess I will stay in Massachusetts for a while, if you have time, you can just read it, and don't forget to give me some comments after reading it." Junxin smiled and stopped Professor Qiu from opening the book.

Hearing this, Qiu Chengtong put the book aside, and said with a smile: "It's okay, then I'll read it at night." But if you watch it at night, I'm usually very strict, so don't blame me for deliberately picking thorns! ”

"Haha, it's good to pick thorns, pick thorns to correct the shortcomings!" Junxin smiled indifferently.

The two talked and laughed again, and soon it was time for dinner. Professor Yau Chengtong naturally did not let Junxin go back like this, but pulled Shi Wanxiong, Cao Huaidong and Zhou Peineng into his car together, and pulled Junxin to the door of a Chinese restaurant with a classical house while talking.

"This is also a special Chinese restaurant in Cambridge, USA, the owner of this store is from JSZJ's area, and the good Huaiyang cuisine is cooked, you are from JS, help me taste whether the Huaiyang cuisine made by the boss is authentic!"

"Then I have to eat it in my mouth!" Junxin also said politely.

Professor Yau Chengtong didn't lie, the Huaiyang cuisine in this store is indeed very authentic, at least it makes Junxin feel the taste of his hometown.

When the four of them stopped halfway through eating, Professor Qiu drank some wine and said excitedly: "It has been rumored in the industry that the International Congress of Mathematicians will award the Fields Medal next year, according to the decision of the last conference, this time it will be held in Warsaw, and the theme of this conference is topology. ”

"For now, the Calabi conjecture you solved has a good chance of winning the Fields Medal." Junxin put down the chopsticks in his hand and said, "As far as I know, in the current topology community, in addition to you, there is also Professor Thurston of Princeton, whose geometric conjecture and three-dimensional manifoliate structure are indeed very exquisite configurations, and probably Professor Kong Nai!" ”

"Well, you're probably right!" Professor Yau Chengtong said with a smile.

"Oh, so there's something wrong with me?" Junxin asked curiously.

"Hehe, you underestimate the influence of your Princeton as the world's mathematics center in the industry." Professor Yau Chengtong said proudly, "You have forgotten yourself!" ”

Jun Xin nodded, in history, whether it is the four-dimensional Pang Jialai conjecture or the moder conjecture, it is a huge mathematical achievement that won the Fields Medal, so he doesn't think that he will not be able to win this award. You must know that the evaluation of the Fields Medal is much more difficult and strict than the Nobel Prize, but the advantage is that the Fields Medal does not have so many ways and shady scenes, and every mathematician who wins the Fields Medal is expected.

However, Junxin still shook his head and said, "To be honest, if the mathematicians at the Institute for Advanced Study in Princeton support me, I really deserve to come to the fourth place." But..."At this point, Junxin hesitated a little.

"But what?"

"But I probably won't be able to attend the International Congress of Mathematicians!" Jun Xin smiled a little helplessly.

"Why?" Professor Yau Chengtong asked with a frown. He is also a professor at the Institute for Advanced Study in Princeton, and one of the twenty-nine tenured professors, and naturally he is also a strong supporter of Junxin, and now when he hears Junxin say this, he naturally can't wait to know why.

Junxin shook his head and explained: "The Executive Committee of the International Mathematical Union is elected at its highest authority, the Congress of the Member States of the International Mathematical Union. The participating countries of the International Mathematical Union are divided into five categories: I., II., III., IV., and v., and the number of voting representatives is 1, 2, 3, 4, and 5 according to the size of the country and the development of mathematics. China and Canada, France, Germany, Israel, Italy, RB Russia, the United Kingdom, the United States belong to the same V., etc. China's seat in the IMU used to belong to China's Taiwan region. At present, Chinese mainland has not resumed its legal seat in the IMU, and it is Taiwan that exercises its rights in the IUM organization on behalf of China. In this way, it means that it is impossible for me to attend this international congress of mathematicians! ”

Speaking of which, Junxin also has some regrets, historically China did not restore all its rights in IUM until 1986, but Chinese mainland is a V. category 5 rights jointly exercised by Colombia and Taiwan, 3 votes from the mainland, and 2 votes from Taiwan, but that was five years later.

Professor Yau Chengtong heard this, his expression suddenly froze, he and his colleagues have never considered this problem, in fact, this is also a common problem of mathematicians or scientists, they often do not understand politics, but many times they are affected by politics, many times they will still "can't help themselves".

"Alas!" Professor Yau Chengtong sighed deeply, looked at the table of dishes, and lost his appetite anymore.
