"Xiaojun, it's good to be involved in many ways, but it's better to choose a direction to specialize." The more Professor Chen looked at Jun Xin, the more satisfied he became, and admonished in a rather serious tone, "I don't want you to be the next Landau. ”

"Well, thank you for your kindness, I'll remember it." Although he did not agree with Professor Chen's opinion, out of respect for Professor Chen, Junxin nodded and agreed.

"Teacher, it's actually nothing!" Professor Yau waved his hand and said, "You know, although I study topology, my research actually includes Mr. Einstein's general theory of relativity. ”

Professor Chen shook his head and said, "He is different from you, his research is too extensive, you must know that he once studied a problem in crystallography, and published it in Nature, or in the form of a supplement." According to Canadian national television, in an interview with scientists from the International Union of Crystallography in Toronto, the famous British chemist Professor Max Peruz even said that he would nominate Junxin for the Nobel Prize next year. ”

"What? It's true? When did it happen? Qiu Chengtong squirted out the tea he had just drunk, and asked eagerly.

"Hehe, of course it's true!" Professor Chen smiled with relief, "Last year, Jun wrote me a letter and asked me to help promote his paper on quasicrystals published in Nature. Later, I didn't pay attention to this matter. I didn't know about it until Professor Krauss, who teaches crystallography at Berkeley, excitedly told me about it and told me about it on Canadian television. ”

"Professor Max Peruz is also a well-known chemist in the field of chemistry, and he was a Nobel laureate in chemistry, so he has the qualifications to recommend." Professor Zheng nodded on the side and said, "Xiaojun, this is true, right?" ”

Junxin smiled helplessly and said, "I have already asked Professor Peruz about this matter afterwards, and Professor Peruz also admitted this matter. ”

"Hehe, you really don't have anything to say to me." Professor Yau Chengtong felt that his face twitched a little, and he really didn't know how to admonish Junxin. Persuade him to devote himself to studying mathematics? The achievements of others in chemistry have reached the point of winning the Nobel Prize in Chemistry, how can people give up? But then again, one's experience is very limited after all, and it is likely that it will be difficult to achieve high achievements in a subject by wasting energy. But Junxin can't use this method to evaluate, if you talk about mathematics, his Moder conjecture is enough for him to win the Fields Medal, on chemistry, ironclad Nobel Prize nomination in chemistry, with his age, if he continues to specialize, a Nobel Prize can't run.

That is, he is still a little lacking in physics, but listening to his words, he only started studying physics a year ago, and he has already solved the problem that a professor has been studying for a whole decade, and if it continues, the achievement is unimaginable.

After thinking about it, his words of exhortation also fell into his stomach and did not come out.

As soon as his thoughts turned, Yau Chengtong no longer regarded Junxin as a junior, but a mathematician of equal status, and asked: "Although Modell's conjecture has been recognized by the world, there will always be some questions and doubts, are you sure about tomorrow's report?" ”

Junxin thought for a while and said, "I think, there should be no problem, the content of tomorrow's speech, I have almost prepared, even if there are some problems, I can only solve them on the spot." However, I have not studied this problem a lot, so it should not be a big problem to deal with it. I would have liked someone to ask some profound questions, because recently in the course of my talk, I have found an interesting question about whether the solution of the Fermat equation proposed by the Modell conjecture is a special case, and if the problem is extended to a common problem. ”

"Oh?" The three of them heard Junxin's thoughts, and their eyes lit up, and they asked eagerly, "What do you say?" ”

Jun Xin waved his hand and said: "I haven't actually raised this question yet, it's just a question that came to mind when sorting out the many problems of Moder's conjecture, I just think this question is very meaningful, but it's just an idea, and a complete idea has not yet been formed, so you three can help me refer to it." ”

"Joked, the three of us are familiar with a few issues, but we are really a little blind in number theory." Professor Zheng said with a smile.

"It's fine, it's just a thought of mine that I don't know if it's right or wrong." Junxin shook his head and said.

What Junxin is talking about is the famous ABC conjecture. The ABC conjecture, first proposed by Joseph Osdali and David Mather in 1985, has never been proven. Its name comes from the practice of referring to the three numbers involved in a conjecture as A, B, and C.

In August 2012, Shinichi Mochizuki, a mathematician at Kyoto University in Japan, proved this conjecture, but because no one understood the research tools and papers, it was impossible to verify whether it was correct or not, and the conjecture has not yet been resolved.

Professor Shinichi Mochizuki is a strange man in the field of mathematics, and his research methods have nothing to do with the research of his predecessors.

He developed a new approach to mathematics, using entirely new mathematical "objects"—abstract entities that can be compared to familiar geometric objects, sets, permutations, topologies, and matrices that few mathematicians can fully understand. As Goldfeld puts it, "He is probably the only one today who has mastered this method completely." ”

Under the repeated requests of the three of them, Jun Xin slowly said this conjecture, but what he said only began to extend from the direction of Modell's conjecture, and then put forward an incomplete conjecture in moderation, and did not say all the content of the entire conjecture.

After all, they are mathematicians who have stood at the top of the world, although Professor Chen, Professor Qiu and Professor Zheng are not proficient in number theory, but they still perceive the problems in the conjecture proposed by Junxin with a very keen mathematical sense, and then the four of them discussed and perfected it for a while, and finally a complete set of conjectures was put forward by the four people.

"Although this conjecture is proposed, I am afraid it is difficult to prove him." Professor Zheng said with emotion.

"Ha, that's maybe, isn't the conjecture put forward to prove it? Maybe one day it will be proven! Professor Qiu said very optimistically.

"The conjecture has been raised, what should it be called?" Professor Chan asked.

"What do you think?"

"If you want me to say, since the conjecture involves the letters a, b, and c, and it is a basic problem in number theory, why don't you call it the ABC conjecture?"
