Chapter 319 (2/2)
”Young people, this is the most brilliant moment of your life - before the college entrance examination! At this time, you know astronomy and geography. There are ellipses and hyperbolas in front of you and hybrid biosphere in the back. You can speak English on the outside, and you can repair ancient Chinese prose on the inside. You can get a series of numbers. You can speak Ma Zhe. You can trace the origin of China for 5000 years, and extend the land and sea of Chizhou to millions... ”
”I know you all dream of walking into that place, having a great love, or meeting a friend who can accompany you all your life, a wanton and publicized youth.”
”You may live there more tired than high school, maybe it is not as beautiful as you think. But in the end, as a senior student, I still want to give you eight words. ”
”In the wind and in the rain, the construction site is waiting for you!”
Click, the video black screen ends.
The students sitting under the podium were stunned for more than ten seconds before they gradually reacted. The whole teaching building also became extremely noisy.
However, in short, this video, can be regarded as an adjunct to ease the tension in the minds of senior three.

Professor Fang's apartment, Tsinghua University.
Cheng Nuo handed a document to Professor Fang, ”Professor, this is some information about group algebraic curves that you asked Professor Tang to pass on.”Strictly speaking, BSD conjecture is a problem in the field of number theory, but different from the elementary number theory conjectures like Goldbach's and prime number conjectures, this conjecture is very complicated.
In addition to number theory, algebra, function, group theory and geometry are also embodied in it.
Professor Tang, as a master in the field of number theory, asked him for some research materials about BSD conjecture.
”OK, put it here first.” Professor Fang, with reading glasses, looked down at another document and said casually, ”by the way, have you copied this information?”
”Er Not yet. ”
”You go downstairs to make a copy and take it back for yourself. In name, although you are my assistant, I don't just ask you to come over and give me a hand in this job. It's easier to turn two brains together than one brain. ”

Let V (m) be the whole of all analytic vector fields on an analytic manifold m, and d be a symmetric subset of V (m) according to the carlesio Dory cycle theorem An integral curve α: [0, t] → m, t ≥ 0, such that α (0) = x, and α (T) = y, but, Professor, what should we do next
”Are n-ary polynomials F1, F2 The system of algebraic equations F1 (x1 ，xn)=0，F2(x1，… ，xn)=0，… ，Fn(x1，… The common solution set in the domain K with xn = 0
At the end of June, Cheng Nuo is in an office discussing the progress of conjecture proof.
Up to now, Cheng Nuo has thoroughly understood more than a dozen drafts containing Professor Fang's two years' hard work. According to Cheng Nuo's opinion, if all the verification process is carried out according to the established route of Professor Fang, then in the first two years, Professor Fang has completed one third of the progress in his spare time.
At present, the progress has reached 40%, which can be almost completed in one year, and the other half of BSD theorem has been proved.
Of course, the premise is that if the research direction is correct and wrong, almost all the efforts of the previous two years will be wasted.
Professor Fang sat in his office chair, squinted at Cheng Nuo's opinion, and said with a smile, ”your method is really good, but it's still a little troublesome.”
Professor Fang pointed his finger at the paper. ”As far as I'm concerned, we can use the combination of complex analytic manifolds and Mobell clusters. If V is a compact complex analytic manifold of complex r-dimension and f (V) is the domain of semipure functions on V, then f (V) is a finite algebraic function domain, and its transcendental dimension s will not be greater than R. in addition, there is also a s-dimensional algebraic family V 'and a semipure transformation t from V to V', so that t can induce isomorphism between F (V) and f (V ')
Cheng Nuo buried his head for a moment, raised his head and thumbed up, ”it's really much easier!”
”By the way, Cheng Nuo, have you signed up for the mathematical modeling contest?” Professor Fang asked with a smile, holding a mug of medlar.
Cheng Nuo: ”it has been reported.”
Professor Fang: ”your two teammates are not really pulling from the road casually, are they?”
Cheng Nuo: No
Professor Fang: ”that's good. That's good.”
Cheng Nuo: ”it's two that I randomly pulled at the registration office.”
Professor Fang:
