Xueba starts with change

Chapter 289 Lend me first (add 9 to last month's monthly pass)

"Huh?" Zhang Shouwu found out about this person first, and he couldn't help but let out a little gasp.

The man looked at Zhang Shouwu with a smile on his face.

Zhang Shouwu immediately asked, "Didn't you say you wouldn't come?"

The man replied: "Isn't this an interesting content?"

After finishing speaking, his eyes turned to Chen Zhou who was looking at him.

Chen Zhou thought about it carefully, it was indeed the first time he met this person, and he didn't know him.

But the other party clearly knew himself.

Seeing Chen Zhou's puzzled eyes, Zhang Shouwu introduced: "This is Professor Zhang Yitang who crashed into your research field."

Chen Zhou suddenly realized that this person can be said to be a "sweeping monk" in the mathematics world.

The so-called no sound is already, a blockbuster.

It probably refers to people like Zhang Yitang.

Before 2013, the nearly sixty-year-old mathematician was a lecturer at a lesser-known university.

Yes, a lecturer, not a professor.

And he has hardly published professional papers related to mathematics.

But since 2013, in just two years, Zhang Yitang's name has "turned out" in the international mathematics community.

He has successively won the "Mathematical Society Cole Prize in Number Theory" in the United States and the 2014 Rove Shock Prize in Sweden.

Zhang Yitang was even invited to give a one-hour invited report before the closing ceremony of the International Congress of Mathematicians in 2014!

Invited talks at the International Mathematical Congress are usually 45 minutes, but his was an hour!

The problem Zhang Yitang studied was precisely the problem of the interval of prime numbers.

In 2013, he published a landmark paper on the study of prime numbers, proposing for the first time that there are infinite pairs of prime numbers with a certain interval between them.

And, he proved that this interval is within 7000 million.

This is also a weakened form of the twin prime conjecture.

As a result, Zhang Yitang became a key figure in solving one of the famous conjectures in the field of mathematics, the "Twin Primes Conjecture".

Because of his work, it is equivalent to Brown of Norway proving "1920+9" in 9, which "opened" the proof of Goldbach's conjecture.

现在，从7000万到6000万，再到4200万、1300万、500万、40万……

Using Zhang Yitang's method, mathematicians have reduced this constant to 246!

It is getting closer and closer to the scope of the twin prime number conjecture.

If this constant is improved to 2, it is equivalent to proving the twin prime number conjecture!

I have to say that this is a very powerful mathematician.

Thinking of this, Chen Zhou also understood the intention of the other party coming over, and he politely introduced himself: "Hello, Professor Zhang, I am a student of Yenching University, Chen Zhou."

Zhang Yitang looked at Chen Zhou and said, "I know you, I have read your paper."

After a pause, he added: "Whether it's the proof of the Hail conjecture or the extended study of the Krammel conjecture, they are all wonderful!"

Chen Zhou smiled modestly and said, "Your research on the twin prime number conjecture is also wonderful! It has opened the door for mathematicians to prove the twin prime number conjecture!"

Zhang Yitang waved his hand and said frankly: "It is only a research method, and it is still far from a proof. Just like Goldbach's conjecture, after being pushed to '1+2', it is still impossible to take a step forward. The last step."

Zhang Shouwu looked at the expressions of the two of them from the side, and immediately interjected: "Okay, you two, don't be modest, there are no outsiders here..."

Hearing this, Chen Zhou and Zhang Yitang looked at each other and smiled.

However, Zhang Yitang is indeed a low-key mathematician.

Otherwise, it would not have been several decades without publishing mathematical papers, so that the mathematics community has forgotten the existence of this person.

Until Professor Zhang Yitang made a big vote.

At this time, the reporter on the stage had also ended his report meeting.

During the QA session, he was hardly challenged.

Giving his own applause politely, Chen Zhou thought that it would be pretty good if his report could be like this on the last day.

"Let's go, let's find a place to chat?" Zhang Shouwu suggested.

Chen Zhou and Zhang Yitang naturally had no objection, the other party had something they wanted to know.

The three of Chen Zhou went to the auditorium and found a nearby cafe.

The waiter warmly entertained the three of them.

Zhang Shouwu didn't treat the waiter's enthusiasm badly, so he gave a tip easily.

Chen Zhou's eyelids twitched as he looked at the tip in the tray.

At this moment, Zhang Yitang's voice brought back Chen Zhou's thoughts.

"Chen Zhou, can you tell me about your distribution deconstruction method?"

Maybe he thought it was a bit abrupt to ask, so Zhang Yitang took out a notebook from his bag, opened it, and asked, "About the derivation of Equation 5-3 and Equation 9-6 in your thesis."

Chen Zhou thought about it for a while and said, "Can you give me a pen and paper?"

Zhang Yitang immediately took out a fresh stack of A4 paper from his bag, and handed the pen to Chen Zhou.

Chen Zhou took the pen and paper, and began to say: "About formula 5-3, it's like this..."

While speaking, he wrote the derived formula on the draft paper.

Zhang Yitang and Zhang Shouwu, two elders, listened attentively to Chen Zhou's narration.

The previous waiter couldn't help but glanced curiously, and suddenly felt dizzy.

These Chinese people don't drink their coffee even when it's cold, but write a bunch of incomprehensible symbols instead.

I can't understand it!

"...From this, the conclusion of Formula 5-3 can be drawn." Chen Zhou stopped writing, and handed the draft paper to Zhang Yitang, "Take a look."

Zhang Yitang took the draft paper and carefully read it word by word.

Finally, he handed the draft paper to Zhang Shouwu, and looked at Chen Zhou with bright eyes: "What about formula 9-6?"

Chen Zhou smiled, and started writing on the draft paper again with the pen in his hand.

"Actually, formula 9-6 uses a technique, I believe Professor Zhang, you must be familiar with it!"

Following Chen Zhou's narration, Zhang Yitang's eyes gradually enlarged, which...

This is similar to my own work on correcting Bombieri-Friedlander-Iwaniec.

But he was able to make these innovations based on decades of research.

But Chen Zhou is only a sophomore undergraduate student now, how can he have such a rich accumulation?
Even if he is sleepless, he can't read so many documents, can he?

What's more, reading literature is not just reading.

Zhang Yitang looked at Chen Zhou who was writing and talking in front of him, and couldn't help but feel a lot of emotion in his heart.

Maybe this is the math talent?

“……这样由式9-3、式9-4和式9-5就可以推导出式9-6了。”

After Chen Zhou finished speaking, he slowly put down his pen and handed the draft paper to Zhang Yitang.

Chen Zhou looked at each other with a smile: "Is there something familiar?"

After Zhang Yitang finished reading it, he finally expressed his emotion: "I didn't expect that your understanding of prime numbers is so high at such a young age..."

Zhang Shouwu also said: "Chen Zhou, you are beyond my imagination!"

If we only look at the thesis, we can only see the results of Chen Zhou's work.

But after Chen Zhou said this, the thoughts in it made them feel even more emotional.

Chen Zhou said with some embarrassment: "Professor Zhang, you are too much for the award."

"Well, Chen Zhou, these two pieces of paper?" Zhang Yitang noticed that Zhang Shouwu was obviously clenching the draft paper in his hand.

"Oh, I'll give it to you." Chen Zhou also noticed Zhang Shouwu's small movements, and only thought that this old man in his 50s was quite interesting.

Hearing what Chen Zhou said, Zhang Shouwu immediately looked at Zhang Yitang: "Old Zhang, let me have a look first!"

As he spoke, he clenched his hands even tighter.

Zhang Yitang was also a little dumbfounded, and waved his hand: "Remember to return it to me after reading it."

Zhang Shouwu immediately said no problem.

Later, Chen Zhou and Zhang Yitang discussed some research ideas on the problem of prime number intervals.
