"Alright, that's the end of the gossip!" Professor Witten stopped the interactive chat between Jun Xin and Professor Dyson, and then said, "Jun, let me introduce you, this is Mr. Horowitz who is about to come to Princeton as a postdoctoral fellow, and he is very interested in your research. ”

"Hello, Mr. Horowitz!" Junxin nodded and said hello, he was naturally very clear about Horowitz Junxin, one of the members of the four-person team of the famous superstring theory research in later generations, and an expert in superstring theory. He is a professor at the Institute for Advanced Study in Princeton, along with Candela Witten and Strominger.

"Mr. Horowitz will study and research questions about the theory of relativity under Professor Yau, and Professor Yau has a high degree of achievement in this area. By the way, Professor Yau is also a professor at our Institute for Advanced Study in Princeton, and a tenured professor. He's lecturing at Harvard right now, and I guess you'll be able to meet him in a while. Witten added.

Horowitz nodded at Junxin as a greeting, he didn't say much, and he seemed a little taciturn.

"Okay, gentleman, that's the end of the gossip, there is a question I want to ask you, the problem of gravitons you explained through the supersymmetric model string theory, the solution of the equation conforms to the conclusion of the theory of relativity, which can be said to solve the problem of graviton, so how do you think about the anomaly problem in supersymmetry? Although Professor Witten has told me this question, I still hope that you can explain it yourself, okay? Professor Dyson said with a serious expression.

"Okay, I'll be happy to help you, Professor!" Junxin agreed without thinking, and then began to slowly explain the relevant content of the I-type superstring theory under the gaze of the three people.

Any of the three people present here are top geniuses in the field of physics, so naturally they quickly understood the general content of the theory that Junxin said and Junxin's ideas.

It is not the first time that Professor Witten has heard Junxin expound on this issue, but even after listening to Junxin explain his views for the second time, he still feels that this theory has high operability and research value.

Horowitz is still a postdoctoral fellow, but being able to stand out among so many researchers around the world and become a postdoctoral fellow at the Institute for Advanced Study in Princeton is enough to show that his attainments and achievements in physics are definitely not low.

Not to mention Professor Dyson, who studied mathematics under Professor Hardy in his early years, and then came to the Institute for Advanced Study in Princeton, where he became an assistant and colleague of Einstein, Hermann-Weyl and Professor Yang Zhenning, and is one of the founders of quantum electrodynamics.

Junxin also expounded his views and contents very heartily, and under his elaboration, the specific content of the I-type superstring theory, as well as some inferences and mathematical geometry pictures and equations were perfectly displayed in front of the three of them. All of a sudden, in the entire office, only Junxin's voice loudly expounded his views were left. The problems of the other three gradually disappeared.

It took about an hour and a half for Junxin to finally fully expound the model of the I-type superstring theory in a dry mouth.

There was a moment of silence in the office.

"It's not the first time I've heard it, but I still think your theory is very exciting. And compared to what you said to me at the afternoon tea discussion last time, you have perfected it. I have to say, this is a great initiative. Professor Witten exclaimed.

Horowitz frowned and said, "It is indeed a very beautiful model, but I have noticed that in order for this problem to succeed, the required dimensions will be at least ten dimensions, how do you plan to solve other dimensions other than the four-dimensional space?" ”

"I have noticed a model of the unity of relativity and electromagnetic forces mentioned by Mr. Caruza and Mr. Klein before, and this theory has inspired me a lot." Speaking of which, Junxin nodded to Professor Dyson and continued, "I think I can solve this problem in an extradimensional way. ”

"Coincidentally, my model is a four-dimensional by six-dimensional model, a model of a four-dimensional space plus a six-dimensional extreme curl up. One of the questions I have been working on recently is how to describe the dimension of six-dimensional curling, and finally I thought of a very important conclusion in the breakthroughs in topology in the past few years, that is, the Calabi manifold proved by Professor Yau Chengtong a few years ago. ”

"The Ka-Chu manifold is a very tiny space that cannot be directly observed with the naked eye, but this six-dimensional space Professor Yau Chengtong has given a perfect proof, which is a very interesting conclusion. Substituting this conclusion into my equation, then the extra dimension required in superstring theory is completely satisfied, and I think there should be no problem in solving this problem. ”

"Is it Professor Qiu's conclusion?" Dyson, Witten, and Horowitz looked at each other, feeling a wave of weirdness. Since he was appointed as a professor at the Institute for Advanced Study in Princeton, Professor Yau has often told them about his research results at gatherings, and although they are not very interested in it, they have no idea that what they are not interested in is actually the key to solving the extradimensional problem in superstring theory. In other words, the extra-dimensional space in superstring theory corresponds to the six-dimensional manifold structure of the Calabi-Yau manifold, which is no longer clear whether it is a coincidence or that nature is inherently constructed in this way.

"Looks like we need to get Qiu back and do a math report on Calaby's conjecture." Professor Witten said with a sigh.

"You can call him now, I don't think he will refuse!" Dyson said with a smile.

"Well, I guess you don't have to call." Junxin said with a hint of uncertainty in his voice.

"Oh? What's wrong? Horowitz asked, Professor Yau Chengtong is his postdoctoral supervisor, and he is naturally very concerned.

"Next Saturday, I will give an academic presentation in the Department of Mathematics at Princeton University, and I heard President William say that he plans to invite mathematicians from all over the United States to come over and do a mathematical exchange activity by the way, and I guess Professor Qiu will not miss this meeting."

"Academic debriefing?"

"Your academic report?"

Dyson and Horowitz both exclaimed in surprise at the same time. The people invited by the Department of Mathematics of Princeton University to give academic presentations were at least internationally renowned people, and they looked at each other and didn't know how Junxin became a presenter.

"Oh, it's a report of the paper that your Modell conjecture proves?" Witten, who knew the foundation of Junxin, suddenly smiled and said, "Congratulations, you are still the first student who can make an academic report in the Princeton Department of Mathematics, especially undergraduates!" Speaking of this, even Professor Witten couldn't help but feel a burst of amazement.

At this time, Dyson and Horowitz remembered what Witten had told them before, that Junxin is still a sophomore exchange student in the mathematics department!

But how can there be such a strong undergraduate in this world?
