Zhou's conjecture, twin prime conjecture, and Fibonacci sequence: Are there infinite prime numbers?

3X+1 hail hypothesis?

Even the Goldbach conjecture, the crown jewel of number theory, which is most respected by Chinese people...

In 1966, after the pride of China, Mr. Jing Run, proved that "1+2" is valid, that is, "any sufficiently large even number can be expressed as the sum of two prime numbers, or the sum of a prime number and a semi-prime number", the strong conjecture of the Goldbach conjecture remains an unsolved mystery.

These conjectures are like pearls hidden in an attic without stairs. If you want to see the splendor of these pearls, you must use your own mathematical knowledge to transform yourself into the stairs step by step, so that you can explore and witness the splendor of those pearls and treasures.

Have you mastered all the basic university textbooks? Have you even delved into the field of number theory, which is only explored by pure mathematics graduate students?

This learning progress once again shocked a group of Kyoto University teachers and student representatives.

Li Yishen was an associate professor in the Department of Mathematics at Peking University. He had some superficial research in number theory and was immediately attracted by the opportunity. He tore off a piece of draft paper, quickly wrote out a math problem, and handed it to Wu Tong.

"Come on, Wu Tong, take a look at this question and tell us what you think!" Li Yishen added this deliberately. He didn't mean to embarrass the child, but just wanted to see how Wu Tong mastered the knowledge through self-study. In the future, when Wu Tong enters school, he can also teach him according to his aptitude.

As long as Wu Tong can simply explain some solutions to the problem without having to actually solve it, he can be sure that Wu Tong has truly learned something.

Several student representatives on the side took a look at the question and felt that it seemed that they knew the words, but the question did not know them. What was going on?

Why does it feel like a dog trying to eat a hedgehog, I don’t know where to start?

Although they are not students majoring in pure mathematics, they are still students of Peking University after all. Why do they seem to have brought shame to Peking University?
