Scholar’s Advanced Technological System

In the field of partial differential equations, the authoritative bull, Ark Zhou thought to go, only Mr. Qiu Chengtong.

With regard to Mr. Qiu's achievements in differential geometry, there is no need to say much.

Turning to the preamble of the Differential Geometry Handbook, one can see the phrase: "He is the founder of the Faculty of Geometric Analysis”.

What is geometric analysis?

is to move the partial differential into the differential geometry.

Although his reputation has been mixed among domestic academics due to sharp contradictions with Yan Dae, the international academic community's reputation for this Chinese scholar is still quite high.

And this can be seen in the honors he has earned.

There are only two mathematicians in the history of the top three awards in the world, including the Fields Award, the Wolf Award and the Kleiford Award, one for the mentor of the Ark, Deligne, and the other for Chengtong Qiu.

At that time, when Chen Province was awarded the Mathematics Award, Ark Zhou and Mr. Qiu had an edge, and since then there has not been much intersection due to different research directions.

NS equations are a problem in the field of partial differential equations, and for the field of partial differential equations, among the scholars known to the Ark, there is no doubt that Mr. Qiu's achievements and knowledge are the highest.

In Cambridge, downtown Boston, Massachusetts, a stunning Ford explorer parked near a mathematics department building.

After getting out of the car, the ark looked around and didn't know where to go.

So he stops a passerby who looks like a mathematician by instinct, and asks.

“Hello, Professor Qiu's office? ”

“Are you looking for Professor Qiu?” The man with glasses looked at the ark with confusion. He always felt that his face looked a little visionary, but could not remember where he had seen it, so he asked, “What do you want with Professor Qiu? ”

Ark: “There are some questions I would like to ask you. ”

Perhaps seeing him was too young to ask any brilliant questions. After hearing this, the glasses man smiled slightly: “Professor Qiu doesn't have time to answer those simple questions. Ask me any questions. ”

The boat smiled and said, “Really? Then you can answer for me, Navier-Stokes equations don't have extraordinary backward self-similar answers. Is that why? ”

The moment I heard the problem, the glasses man even stunned.

However, reluctant to admit that he could not come up with it, he began to think about it. Yet frowned for half a day of meditation and did not figure out how to answer that question.

It can be seen that the Semi-Differential Equation should be his specialty, and he knows something about the Navier-Stokes equation.

But it is also clear that he did not go deep enough into his profession, or that the direction of research was not there.

Otherwise, it would be easy to know if he had a little research into the Navier-Stokes equation, which was actually answered by three mathematicians, such as Necas, in 1995.

The boat looked at the table and said casually: "Can I take you now? ”

“Yes, brother, you did ask me,” The glasses man smiled, barely nodded, "... come with me, but Mr. Qiu is a busy man, I can't guarantee that he will see you. ”

The Ark laughed and didn't say anything, followed him.

Walking down the road and talking, Ark learned that this benefactor's name was Zhao Xiao, graduated from Shui Mu, is now studying in Harvard Mathematics and studying direct from Professor Steve Nadis, Mr. Qiu's best friend.

“Are you a freshman in undergraduate school? ”

Instead of denying it, the Ark asked, “Why say that? ”

Zhao Xiao grinned: "Because your hair looks quite much younger. ”

Ark: …?

This…

Is that a reason?

Without stopping, Zhao Xiao continued his conversation: "… Your question, perhaps from a reference book, but I suggest that before studying these frontier areas, it is best to focus on the knowledge of this specialty, lay a solid foundation, more important than studying the contents of those hyperbola from a distance. ”

This brother-in-law is interesting, not bad, just a little too enthusiastic.

If you become a professor in the future, you will certainly be loved by diligent students.

The Ark laughed: “That makes sense. I was taught. ”

Seeing this “schoolbrother” so taught, Zhao Xin's heart was not happy, so he smiled and said generously: “Everyone is compatriots when they go out, it is right to help each other. Anything you don't understand can come to me, call me Brother Zhao, or Brother Four Fire! ”

Ark: “Then call me Brother Four Fire. ”

That name sounds interesting.

Zhao Xiao said with a smile: "You know my name, that schoolbrother, what is your name, should tell me too. ”

“Ark. ”

Lu... Boat?

Zhao Zhao stunned, frowned, and his brain didn't turn for a while.

As they were walking, they had arrived at the door of Mr. Qiu's office.

Although the office door was open, the ark knocked slightly out of courtesy.

Mr. Qiu raised his head after stopping the pen in his hand and writing in an ambush.

When he saw the man who appeared at the door, the old man first slightly stunned, then the frown locked because of his thoughts, stretched a merciful smile.

“Yo, Rare Customer,” put the pen down, Mr. Qiu rose from the chair and greeted the door with a smile, “What brings you out of Princeton's cabin? ”

The Ark laughed and humbled: “There are a few bottlenecks in research that I would like to teach you about the differential equation. ”

Watching Mr. Qiu's attitude toward the young man, Zhao Zheng's brain stood at the door and crashed on the spot. He stood there in disgrace.

At this moment, he always remembers why the sense of vision came...

When he thought about putting on the old man for half a day, he was ashamed to find a stitch in the ground.

Didn't notice the change of expression on the man's face at the door. After hearing the instructions from the ark, Mr. Qiu's eyes flashed a hint of interest.

“Bipolar equations? This is an area I am familiar with. Can you tell me the exact direction? ”

“It has to do with the NS equation. ”

Slightly stunned, Mr. Qiu's eyes became more and more interested in the divine color.

“NS equation? That's an interesting question... sit down, I'll go find my teapot, I'm afraid I won't be able to finish this conversation for a while. ”

The ark nodded and sat at will by the tea table.

At this time, Mr. Qiu suddenly noticed that the person was still standing at the door and hesitated slightly.

“… are you? ”

Zhao Qiang stood up and said: “I am Zhao Qiang, studying Bo with Professor Steve Nadis! ”

“Oh, Professor Nadis' student," Mr. Qiu hesitated and pushed his glasses, "… so you sat down? ”

“No, no,” Zhao Xiao shook his head, scratching his head and smiling, “I just brought Professor Lu here, so I wouldn't bother the two bosses to discuss business. ”

While listening to the Big Brothers share math issues, it certainly helps with their own research.

But sitting next to these two great gods, for one of his little transparency, the pressure is really too much...

“It's all about learning, there's no big boss,” Mr. Qiu laughed and waved at the young man when he heard this interesting statement. “Come and sit down and drink some tea before you go. ”
