Chapter 344 (2/2)

But that's for fresh graduates.

Cheng Nuo is a genius who directly shortens the four-year course to two-year study. Naturally, the standard will be different.

Professor Fang and Cheng Nuo have passed a gas in advance, saying that if you want to successfully pass the graduation defense, you'd better prepare a graduation thesis with your own mathematics level. Otherwise, the teachers in the defense group may not be able to let Cheng Nuo get the graduation certificate so easily.

This makes Cheng Nuo have some toothache!

A thesis with your own mathematics level?

Cheng Nuo asked Professor Fang about the subtext of this sentence.

Professor Fang told Cheng Nuo that, in a nutshell, the college hopes Cheng Nuo can prepare a graduation thesis that is qualified to be included in SCI journals at the bottom of the district.

Hiss -

Cheng Nuo takes a breath of cool air.

I Is it so powerful?It was a SCI journal paper in a district. Although it was only the SCI journals that ranked at the bottom of the list, there were five or six influencing factors.

Even some professors in Chinese universities do not mean that they can easily write a one area paper.

Other students may get a high score for a paper at the level of domestic core journals, and full marks for papers in SCI journals of two or three districts, but they can do well on their own. Only papers at the level of SCI journals in one district are qualified to be noticed by the defense group.

Well, it's hard to be a genius these days!

It seems that it is not realistic to write a SCI thesis at the level of two or three districts and pass the graduation defense in troubled waters.

In this way, it can only be positive.

This is why Cheng Nuo stayed in the library thinking about the contents of his graduation thesis.

On his desk, there is a large pile of books.

Functional analysis, methods of mathematical physics, review of modern number theory

Cheng Nuo's eyes are empty and inanimate. It seems that he is wandering in the world, but his mind is constantly running at a high speed.

There are many theories that can be used as a thesis in my mind, but the academic value is not high, far from the level required by Cheng Nuo.

Space theory of functional equations?

No way. This knowledge is too simple to have any profound views.

What about nonlinear evolution equations and infinite dimensional dynamical systems?

This is not the case. Partial differential equations are not in the field of deep research.

…………

Thoughts of Cheng Nuo, helplessly open his eyes, he sighed.

Still no idea?

He twisted his neck, picked up the book ”summary of modern number theory” on the table, and casually turned to a page.

Page Title: Bertrand hypothesis.

Cheng Nuo looks from the beginning.

Bertrand's hypothesis is: for any natural number n ≥ 2, there exists at least one prime number P such that np2n.

It was proposed as a hypothesis by the French mathematician Joseph Bertrand in 1845. Bertrand verified the case within 3000000. In 1850, the Russian mathematician pafnuty Chebyshev (1821-1894) gave the first strict proof of the hypothesis. So Bertrand hypothesis is sometimes called Chebyshev theorem.

It took two hours for Cheng Nuo to read Chebyshev's concrete proof process, and then frowned tightly.

Complicated, it's too complicated!

In Chebyshev's proof process, Cheng Nuo couldn't find any other evaluation except for the complex word.

That pile of formula characters see Cheng Nuo, who has been used to it for a long time, has some scalp numbness.

Just as Cheng Nuo clears up his mood and is ready to turn back, his movements suddenly stop. In his mind, he seems to think of something
