Junxin, who was preoccupied with Professor Chen's academic discussions, did not notice that the discussion between the two of them had attracted the attention of two other prominent Chinese mathematicians in the room. Seeing that Junxin and Professor Chen were talking so warmly, the two of them were naturally interested, so without a trace, they slowly left their conversation circle and came to the side of Professor Chen and Junxin.

The two did not join in the conversation between Junxin and Professor Chen at the beginning, but stood behind Professor Chen and Junxin more respectfully, paying attention to the content of the conversation between the two. This is actually a default rule in the academic world, not everyone can join the conversation between the two at will, first of all, you must have an understanding of the topic discussed by the two and have your own opinions, so that joining the circle will not seem abrupt, otherwise you will be excluded.

However, as the world's top mathematicians, and even recognized as the two leaders who established the discipline of geometric analysis, Professor Yau Chengtong and Professor Zheng Shaoyuan are not unfamiliar with the differential geometry that the two are chatting and communicating.

“… I have published in a paper about the solution of this schematic equation, and after using differential calculus to analyze it, I came to the ...... "Professor Chen spoke very carefully, and Junxin also listened very carefully. The two did not realize that Professor Yau Chengtong and Professor Zheng Shaoyuan were already standing behind them.

"It's "Hermitian's Demonstrative Class of Manifolds", which you made after 1943 when you were invited by Mr. Oppenheimer to the Institute for Advanced Study in Princeton, and I think there should still be a copy of your published papers at that time, Teacher, in the Institute for Advanced Study!" After Professor Chen finished talking about this question, Professor Yau suddenly interjected.

Only then did Jun Xin and Professor Chen realize that Professor Qiu and Professor Zheng had unknowingly stood behind them. Junxin hurriedly stood up and saluted the two professors.

"You're welcome, Brother Shaoyuan and I came uninvited and disturbed the discussion between you and Junxin, teacher, it's already a sin." Professor Yau said with a smile, apparently looking happy now.

"It is appropriate for the seniors to be in front and the juniors to serve on the side, Elder Chen, you don't have to be polite. And this Mr. Junxin is the same, I hope we rushed forward and didn't disturb the two. Zheng Shaoyuan also said politely. Professor Zheng Shaoyuan was born in Taiwan and is the president of National Tsinghua University in Taiwan, which is in the same vein as China's local Shuimu University, so Junxin also has a certain understanding and affinity for him.

After the four of them sat down one after another, Professor Chen spoke first: "I didn't expect that this time I came to Princeton to gather several of our Chinese mathematicians, which is really rare!" ”

"I used to have similar thoughts." Professor Yau Chengtong straightened up and said, "Actually, I have always wanted to set up a conference with our Chinese mathematicians as the center and the main body, but in the end, I have not been able to do it because of this or that thing. ”

Jun Xin secretly said that this should be the original idea of the later Chinese Mathematician Conference. Professor Yau had the idea of planning and establishing the World Congress of Chinese Mathematicians, but it was not until the late nineties that it was actually established. This has absolutely to do with the fact that he is at the peak of his research career.

The golden research age of a mathematician is within the age of forty, and being older than forty years old does not mean that there is no way to make research, but that after the age of forty, people tend to have a fixed routine in the four dimensions, and it is difficult to make major breakthroughs. Therefore, even though Professor Yau had a lot of enthusiasm to establish such a conference body, he would not put a lot of energy into it.

"I don't think there's a rush on this matter." Junxin said with a slight gloom, "The domestic political atmosphere has just improved, and as a local scientific cause in China, it has just gotten rid of its troubles, and there is a long way to go to establish such a conference." ”

The four of them were silent for a while, they didn't want to evaluate anything about the ten years of catastrophe, because for a scientist, the most important thing is not the past, but the future, but there will always be a little sadness in their hearts.

"Forget it, let's not talk about this topic. I just heard you talking to your teacher about differential geometry? Professor Yau Chengtong said with a little surprise, "I beg your pardon for being rude, I remember that most of your research results are focused on number theory, right?" Whether it is the Model conjecture, the Junxin inference, or the twin prime conjecture just published in Acta Mathematica Sinica, why did they suddenly become interested in geometry? ”

Jun Xin shook his head and said: "Actually, I am not all studying the problems in number theory, the problem of the twin prime conjecture is after discussing with Professor Wang Yuan, borrowing the estimation method left by Professor Hardy, which is outside the scope of number theory, although the other solutions are also the content of number theory, but more in algebraic geometry problems." My teacher, Professor Hu, studied in France, having studied at the École Normale Supérieure and the Institut des Hautes Etudes Supérieure in Paris, France, and was a disciple of Mr. Grothendieck, but although he studied algebraic geometry, he was more interested in number theory. Actually, I am much the same as him, although I studied number theory, I am more interested in algebraic geometry. ”

After a pause, Junxin continued: "When I was studying algebraic geometry, I found that I was thinking a little specious about many problems, so I just wanted to dabble in some things to make up for some of my basic deficiencies. What's more, I'm only eighteen years old now, and it's not a bad thing to dabble in all kinds of disciplines, on the contrary, the different thinking between these disciplines can give me more inspiration, and the four-dimensional Poincaré conjecture is also inspired by this. ”

"Four-dimensional Poincaré conjecture?" Professor Zheng and Professor Qiu looked at each other and asked in unison.

"He told me just now!" Professor Chen smiled and said, "It was the result of his discussion with Professor Mirno and Professor Thurston, and I just learned about it. ”

Professor Yau Chengtong suddenly looked at Jun Xin with bright eyes and asked, "Can you tell us what you think?" ”

"Naturally, you can, and you and experts like Professor Zheng are invited to correct it." Junxin nodded without hesitation and said.

At this time, Professor Milno, who had been paying attention to Junxin, and Professor Steele-Smale, who was talking to him, saw that Professor Yau Chengtong was looking at Junxin eagerly, Professor Milno immediately seemed to think of something, immediately put aside Professor Thurston and Professor Smale, and quietly came behind the four of them, pricking up his ears.

Professor Thurston and Professor Smale, who had noticed Professor Mirno, were suddenly curious, and they couldn't help but follow behind. In the same way, the mathematicians who observed these three in the hall also noticed their movements at the same time, and they couldn't help but silently think in their hearts: "What are these four Chinese people discussing?" Then he involuntarily leaned over.
