Junxin, who hadn't noticed anything strange in the hall, sorted out his thoughts a little, and began to explain the idea of a proof of the four-dimensional Poincaré conjecture.

The people around were quiet, Junxin said the rise, and even picked up the white paper on the table, and began to write slowly, as the formulas and equations were presented on the paper, Junxin's ideas became clearer and clearer, and it took more than an hour or so to explain the proof of the four-dimensional Poincaré conjecture.

After a long time, Professor Mirno suddenly spoke, "Jun, is this what you are talking about?" Sorted out these equations, it is a wonderful paper, which we have included in the Annals of Mathematics. ”

"Professor Mirno, why are you? Everyone, why are they all here? Junxin was startled by Mirno's voice and asked in surprise.

Professor Chen smiled and said, "He was standing there with Steele and Professor Thurston just as you were about to explain your thoughts. As for everyone, when I saw the two Fields Medal winners standing there "sneakily", I was curious and followed, and by the way, I heard your thoughts. ”

"I have to say, you are humble, Jun." As soon as Professor Chen finished speaking, Professor Yau Chengtong also said, "Originally, I just thought that you were just like what you said, just a little bit of thinking, but now it seems that you don't just have a little idea, and you almost get the whole process out." ”

Jun Xin smiled and said, "That's based on the study of Professor Donaldson, I'm just going one step deeper. ”

"Oh, dear gentleman, I think it's my pleasure." At this time, suddenly a white professor about the same age as Yau Chengtong suddenly spoke, and it was obvious that he was Professor Donaldson. Like Professor Yau, he is a professor at Harvard University and one of the founders of analytic geometry. I saw him continue, "Your thinking just now is very beautiful, which makes me see another hill!" ”

"Jun, well done!" Professor Thurston said excitedly.

"Very beautiful idea, perfect!" Even Professor Smale, a veteran of Poincaré's conjecture researchers, was amazed. Topology was the most rapidly developing branch of mathematics in the second half of the twentieth century, and even rivaled the branch of algebraic geometry in the Grothendieck era. Unfortunately, however, the Wei Yi conjecture, which is a fundamental problem in algebraic geometry, has been successfully proved under the guidance of Grothendieck's algebraic geometry, but the Poincaré conjecture, which is a fundamental problem in the field of topology, has not been proved until now, which has led to the fact that the achievements of topology have always been below algebraic geometry. This also makes the research to prove Poincaré's conjecture more and more urgent and hot, and it is also why the Poincaré conjecture was the first to be proved in the "Seven Mathematical Problems of the Millennium".

Now, in the eyes of this group of mathematicians who are eager to solve the Poincaré conjecture, they suddenly heard a major breakthrough in the Poincaré conjecture at this mathematical exchange meeting, and such a surprise is indeed a little unresponsive.

Junxin didn't speak, he just kept a smile on his face, and kept nodding his head in the midst of this piece of exchange.

"Jun, write your ideas into a paper as soon as possible, I and Professor Thurston jointly recommend it, I think the editorial department of the Annals of Mathematics will be very interested in your article." Professor Mirno reminded again.

"Uh, Professor, this time it's an academic discussion of the Modell conjecture, right?" Junxin asked in a low voice.

"Hehe, it's not all!" Professor Richard Feverman, who had not spoken on the sidelines, said with a smile, "I just invited all mathematicians in the United States to have an academic discussion through your presentation, and it is not limited to the Modell conjecture." ”

"Alright! I know, I'll write my paper as soon as possible. Junxin nodded and said.

"To tell you the truth, Jun, based on the results of your paper, I don't think Professor Thurston will let you pass the exam." Professor Mirno laughed again.

"Me?" Professor Thurston touched his chin and said with a smile, "If it were me, I would have awarded him a doctorate, but unfortunately I can't replace the members of the degree committee." ”

"Haha, if you don't grant it to Princeton, we at Harvard University are very willing!" Professor Yau Chengtong couldn't help but smile and said.

"And our mit!"

"Don't forget about us Berkeley." Professor Smale said.

"Oh, I think our Stanford University is pretty good, Jun, why don't you think about it?"

Seeing that this group of professors suddenly began to dig up the corners, Jun Xin also twitched the corners of his mouth, unable to say a word.

………

After a period of crooked buildings, the topic gradually returned to academics. After the professors left one by one, Professor Chen suddenly asked, "Xiaojun, do you know Professor Schwartz?" I'm talking about that USC professor John Schwartz? He is from the Department of Physics and studies string theory. ”

"Oh, acquaintance! What's wrong? Jun had a guess in his confidence, but he still asked.

"Nothing, Professor Schwartz asked me two days ago to come to Princeton for this conference, and I thought it was strange, so I asked him why." Professor Chen paused, and an extremely strange smile appeared on his face, "He said that he wanted to meet with you for a detailed chat because one of your papers solved his research topic for more than ten years. But he didn't say what kind of paper it was, Xiaojun, I basically have collected your papers, but, what kind of article is it? ”

Jun Xin said: "When I was at Mizuki University, because I solved the Modell conjecture, the school adopted a free-range policy for me, so I was also exposed to other disciplines while studying mathematics, among which I was more interested in the content of high-energy particle physics, so I even worshipped Professor Zhou of Mizuki University as a teacher to learn quantum theory and relativityWhen I brought in a theory of physics, supersymmetric string theory, and solved the graviton problem, I published my paper in Physical Review Letters, which happened to be Professor Schwartz's research field, so I corresponded with him. ”

"I suppose Professor Schwartz is coming to me for this question, well, how are you...?"

Before he finished speaking, Junxin suddenly found that the three of them were looking at him with strange and incredible expressions.
