Chapter 470 (2/2)
Cheng Nuo's purpose is very simple, but it seems that Mu Leng is not very appreciative. After staring at Cheng Nuo with the eyes of looking at animals, he turns and leaves.
To be honest, Cheng Nuo has a little heartache.
The faculty apartment building is located in the south of Tsinghua University.
This building Cheng Nuo doesn't come once or twice. After all, Professor Fang lives in this building.
Even if I haven't been back to Tsinghua for a year and a half, the memory of school has never been erased in Cheng Nuo's mind.
Cheng Nuo's apartment is located on the second floor, and the upper floor happens to be Professor Fang's residence.
Opening the door, Cheng Nuo glanced around and nodded with satisfaction.
Furniture, home appliances and other things are not lacking, but perhaps because no one has lived for a long time, the house is a bit cold.
After sorting out the luggage, Cheng Nuo went upstairs and knocked on the professor's door above the building.
”Cheng Nuo, are you back?”
Professor Cheng's face is opened by Pang Fang.
”Well. I'm back. After this time, I will not leave! ” Silence, Cheng Nuo said with a smile.
”I know, I know.” Professor Fang patted Cheng Nuo on the shoulder, ”I've heard all about you in foreign countries. I didn't expect you to be better than I thought”It's still a teacher. You're a good teacher.”
”Ha ha, you boy, don't stick gold on my face any more. I'm still very clear about my own level.”
”Come, don't stand at the door. Let's go in and talk
Living room sofa, Cheng Nuo and Professor Fang sit down.
”During this period of time, you are very popular in the international geometry field. I can hear from you from time to time when I stay in China.” Professor Fang said with a smile, ”why, after coming back this time, or continue to prepare for the study of geometric direction?”
”No Cheng Nuo shook his head. ”In the field of geometry, I've almost reached the limit. I can only expand in breadth, but in depth, it's hard to move forward.”
”So, after returning home this time, I intend to make a different one.”
”What? Number theory or algebra? ” Professor Fang is very interested.
”BSD guess!”
Professor Fang was stunned.
Cheng Nuo's words are not surprising and endless, ”I want to prove the complete version of BSD conjecture!”
After a while, Professor Fang stood up directly from the sofa.
BSD conjecture, one of the seven mathematical conjectures of the millennium.
Speaking of this conjecture, Professor Fang is no stranger at all.
A few years ago, Cheng Nuo, who was an undergraduate at that time, took a year to prove the simplified version of this conjecture: weak BSD conjecture!
But the weak BSD conjecture is not on the same order of magnitude as the complete version of the BSD conjecture.
A simple measure is that the weak BSD conjecture is only half of Jacobi's conjecture, but the complete version of BSD conjecture is five times more difficult than Jacobi's conjecture!
”Are you sure?” Professor Fang stares at Cheng Nuo.
”No, to be honest.”
Professor Cheng rang's reply.
Cheng Nuo explained, ”it's not 100% sure, but I think I can try it.”
That is BSD guess after all!
Even in the seven mathematical conjectures, BSD conjecture is not the simplest one.
In the face of this towering mountain, Cheng Nuo is not confident that he will be able to climb it without really climbing it.
Moreover, compared with other mathematicians, Cheng Nuo has an advantage.
That is, he has proved the weak BSD conjecture, which will undoubtedly benefit him.
Seven mathematical conjectures!
It's a great honor to solve one of them.
Cheng Nuo long coveted, now, he is ready to start the impact!
