Scholar’s Advanced Technological System

In the field of partial differential equations, the author is full of authority, and Lu Zhou thinks about it, and only Mr. Qiu Chengtong is old.

Regarding Mr. Qiu Lao’s achievements in differential geometry, there is no need to say much.

Turning on the preface to the "Differential Geometry Handout", you can see the phrase "he is the founder of the geometric analysis school."

What is geometric analysis?

It is the method of partial differentiation that moves into the differential geometry.

Although the domestic academic circles have a mixed reputation for their sharp contradictions with Yanda, the international academic community’s evaluation of this Chinese scholar is still quite high.

And this can be seen from the honors he has obtained.

At the same time, there are only two mathematicians in the history of the world's top prizes including the Fields Medal, the Wolf Prize, and the Clayford Award. One of them is Lu Zhou's mentor, Deligne, and the other is Qiu Chengtong.

At the time of the award of the Chen Shengshen Mathematical Award, Lu Zhou and Mr. Qiu Lao had a relationship, and since there were not many intersections because of the different research directions.

The ns equation is a problem in the field of partial differential equations. For the field of partial differential equations, among the scholars who know Lu Zhou, there is no doubt that Mr. Qiu’s achievements and knowledge are the highest.

A sturdy Ford explorer in Cambridge, Massachusetts, in the metropolitan area of ​​Massachusetts, is parked near the building of the Department of Mathematics.

After getting out of the car, Lu Zhou looked around and didn't recognize how the next road went.

So, he used his intuition to stop a passerby who looked like studying mathematics and asked.

"His classmates, may I ask, how does Professor Qiu’s office go?"

"You look for Professor Qiu?" The boy with glasses looked at Lu Zhou with a puzzled look. He always felt that this person looked at some of his sense of sight, but he couldn’t remember where he had seen it, so he asked. "What do you think of Professor Qiu?"

Lu Zhou: "Some questions I would like to ask."

Perhaps it is to see him too young, not like the question of what kind of brilliant question can be asked, after the glasses man heard this sentence, smiled a little: "Professor Qiu can not answer your simple questions, what is the problem you directly Ask me."

Slightly squatting, Lu Zhou then smiled and said, "Yes? Then you can answer for me, is there a non-trivial backward self-similar solution for the navier-stokes equation?"

At the moment of hearing the problem, the glasses man was even stunned.

However, he did not want to admit that he could not think of it. He began to think about it. However, frowning and thinking for a long time, did not figure out how to answer this question.

It can be seen that the partial differential equation should be his specialty, and he also knows about the navier-stokes equation.

However, it is also obvious that he did not go deep enough into his major, or that the research direction is not on it.

Otherwise, it is not difficult to know that he has studied the navier-stokes equation. This problem was actually answered by a three-digit scientist such as Neas in 1995.

Lu Zhou looked at the table below and said casually: "Can you take me now?"

"Yes, brother, you asked me," the glasses man smiled and nodded. "... Come with me, but Mr. Qiu Lao is a busy man. I can't guarantee that he will meet you. ”

Lu Zhou smiled, did not say anything, followed him behind.

Talking on the road, Lu Zhou learned that this man’s name is Zhao Wei, graduated from Shuimu, and is currently studying at the Harvard Mathematics Department. He is reading at Professor Qiu Lao’s good friend, Professor Steve Nadis. Direct blog.

“Are you a freshman in the undergraduate department?”

Lu Zhou did not deny, but asked: "Why do you say this?"

Zhao said with a smile: "Because your hair looks quite a lot, it looks younger."

Lu Zhou: ...?

This……

Is it a reason?

Didn't stop here, Zhao Wei continued to talk and said: "...you have to see the question from which reference book, but I suggest that you should concentrate on the research of these frontier areas. With the knowledge of this profession, it is more important to lay a solid foundation and study the content of those super-classes.

This man is very interesting, his heart is not bad, it is too warm.

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

Lu Zhou smiled: "It makes sense and is taught."

Seeing that this "school brother" was so taught, Zhao Xin was happy in his heart, and he smiled heartily and said generously: "When you go out, everyone is a compatriot, and it is appropriate to help each other. If you don't understand anything, you can come and find it." I, call me Zhao brother, or four fire brothers!"

Lu Zhou: "That is called the four fire brothers."

This name sounds interesting.

Zhao Yan said with a smile: "My name, you know, the school brother, what is your name, you should tell me."

"Lu Zhou."

Land... boat?

Zhao squatted and frowned, and the brain had not turned around for a while.

Walking, the two have already arrived at the door of Mr. Qiu Lao’s office.

Although the office door was open, but out of courtesy, Lu Zhou knocked on the door.

Stopped the pen in his hand, and Mr. Qiu Lao, who was writing at the desk, looked up.

When I saw the man who appeared at the door, the old gentleman first squatted down, and then the brow that was locked because of thinking, stretched a kind smile.

"Hey, rarity," put down the pen in his hand. Mr. Qiu Lao got up from the chair and smiled and greeted him at the door. "What wind blows you out of Princeton's hut?"

Lu Zhou smiled and said modestly: "There was a bottleneck in the research and I would like to ask you some questions about partial differential equations."

Looking at Mr. Qiu Lao’s attitude towards the young man, Zhao Wei’s brain standing at the door crashed on the spot and stood there with a stern look.

At this moment, he always thinks about it, that is why the sense of sight comes from...

Thinking of the forced squad of the big man for a long time, he suddenly shyly wanted to find a seam on the ground.

Did not notice the change of expression on the face of the man on the door. After hearing the explanations from Lu Zhou, Mr. Qiu’s eyes flashed a look of interest.

"Partial differential equations? This is the area I am familiar with. Can you tell me exactly what direction?"

"Related to the ns equation."

Slightly smashed, the look of interest in Mr. Qiu Lao’s eyes is getting stronger and stronger.

"The ns equation? This is an interesting question... sit down first, I am going to find my teapot. I am afraid this topic will be over for a while."

Lu Zhou nodded and sat down beside the tea table.

At this time, Mr. Qiu Lao suddenly noticed that the person still stood at the door, slightly hesitating.

"……you are?"

Zhao Wei quickly stood up and said: "I am Zhao Wei, reading Bo at Professor Steve Nadis!"

"Oh, Professor Nadis's student," Mr. Qiu Laos hesitated, pushed his glasses, "...and you sit?"

"No, no," Zhao said, shaking his head and scratching his head. "I just brought Professor Lu to come over and don't bother the two big men to discuss the business."

Although listening to the mathematics problems of the big brothers, it is certainly helpful for their own research.

But sitting next to the two great gods, the pressure on him is too big for a small transparency...

"It’s all about learning. There is nothing big about it." Hearing this interesting speech, Mr. Qiu Lao laughed and waved at the young man. "Come and sit down, say, drink too." Go for the cup of tea."
