Chapter 312 Temporary leisure

News that the White House had canceled the plan quickly spread around the world.

The plan had been announced for a long time, but it was canceled directly because of one person's response, especially since it was a plan from the White House.

In an instant, this news swept the world.

This time, every country paid attention to this matter, and at the same time, countless eyes also turned to Lin Xiao.

Does this scientist actually have such a deterrent effect?

In China, there was even more excitement over this incident.

This time I really won.

Ameirika actually compromised. This was something that would have been impossible to happen before, but now it actually happened.

Hundreds of millions of netizens felt extremely excited. Discussions on major forums were filled with excitement, and more people rushed directly to Lin Xiao's account, setting off another wave of "worshiping gods" trend. .

This craze has even affected two neighboring countries.

Netizens in Korea and Japan became sour.

Why is Lin Xiao from China?

Why don't they have such great scientists?

Netizens in both countries felt extremely jealous and began to comment on external software such as Twitter and YouTube. This also caused domestic netizens to quarrel with them.

Of course, not only Japan and South Korea, but people from every country in the world are envious of China for having scientists like Lin Xiao. For example, netizens of YouTube Wuchang are also excitedly commenting on the Internet.

This kind of network traffic effect is probably higher than Jay Chou releasing a new song, and it is weaker than the Open Mind event.

However, compared with this kind of popularity across the Internet, Lin Xiao, as the protagonist, is not too excited.

When he learned the news, he was in his office at Beijing University.

The person who told him the news was his graduate student.

His graduate students include one doctor and two masters. The doctoral student is named Chen Mingkai, and the two master students are named Zhao Guodong and Li Min.

At this time, the three people were looking at Lin Xiao with admiration.

Chen Mingkai: "Professor, my admiration for you is like a torrent of river water!"

Zhao Guodong, Li Min: "Me too!"

Chen Mingkai: "That old Bden, he withdrew his previous plan just because of your words. You are my master!"

Li Min and Zhao Guodong: "Me too!"

Chen Mingkai: "I..."

"Okay, okay, stop talking."

Lin Xiao was speechless and waved his hand to stop them from continuing.

He was not proud of this matter. He was just confused. Is the other party compromising now?

Not even wrangling?

He originally thought that the other party would at least have a negotiation, such as asking them not to conduct research and development of semiconductor materials before they would cancel the plan, or asking them to purchase a share of semiconductor raw materials from foreign companies if they produced chips. Than wait.

As a result, these arguments have not gone through, and the other party has simply given in.

When something goes wrong, there must be a monster, which always makes him have some bad suspicions and worries in his heart.

In the end, he shook his head and stopped thinking about it. He turned around and glanced at the three students who were still standing next to him, and said angrily: "Okay, stop crowding next to me. Have you finished reading today's paper? And Chen Mingkai, you can choose a doctoral thesis topic as early as possible in other disciplines, but for our mathematics doctoral thesis, you still have to decide which direction you want as early as possible. Don’t wait until you finish your Ph.D. before choosing. And as my students, I have three things for you: There are quality requirements for personal graduation thesis, and it must be able to be published in the second district at least."

After hearing Lin Xiao's words, the three people suddenly showed helpless expressions.

Although being able to become Lin Xiao's graduate students has proven their excellence, but thinking about the past achievements of the man in front of them, all kinds of mathematical conjectures seemed to be turned into waste by him.

So God knows how high their beloved Professor Lin’s requirements are for their graduation thesis.

If they were asked to try to prove those well-known mathematical conjectures, they might as well wait.

Unless Professor Lin teaches them step by step how to write all the proofs.

Looking at the appearance of these three guys, Lin Xiao guessed what they were thinking and said: "Don't worry, I won't ask you to choose a topic that is too difficult, but it must be at least higher than your level." For papers of a higher level, I have already read your previous papers and know your approximate abilities, so I will not let you do difficult topics."

The three people immediately breathed a sigh of relief. A higher level?

That's fine, they won't be able to accept it even if it's two levels higher, as long as it's not higher than the atmosphere.

"Also, it's rare for me to come here today, so if you have any questions, don't hesitate to ask me. Of course, for a period of time after that, I will basically have nothing else to do. If there are no accidents, I will come here every day. However, if When I have other things to do, it will probably be difficult for you to see me."

Upon hearing this, the three people immediately started moving.

The three of them enrolled in school in September this year. After enrolling, Lin Xiao was working on the final issue of the X-ray plan, so except for meeting them once and having a meal at the beginning of school, they rarely saw each other after that.

So Lin Xiao directly entrusted them to Xu Ji and asked Xu Ji to help teach them when he was not at school.

When Xu Ji was approached by Lin Xiao, he laughed and scolded him: "Do you think of me as your little boss?"

Graduate tutors are known as big bosses, and the big boss is the mentor. However, if the big boss is busy, he will hand over the students to the smaller bosses to help guide them.

Of course, even though he said so, Xu Ji naturally did not refuse and regarded him as his disciple. As an academician, it was naturally no problem for him to teach these three people.

Of course, Chen Mingkai and the other three would definitely prefer Lin Xiao to teach them personally. After all, they signed up to be Lin Xiao's graduate students just for Lin Xiao's sake.

So as soon as Lin Xiao told them to hurry up and ask if they had any questions, they immediately asked Lin Xiao all kinds of questions that they had not remembered before.

The first is Chen Mingkai. Chen Mingkai is a Ph.D. His research direction is algebraic geometry. He is quite confident in choosing this direction. After all, algebraic geometry is one of the most difficult mathematical directions. If you dare to study this and make achievements, you must be talented. Yes, and his problem is certainly not simple.

He asked: "Professor, look, why is a single variable a in domain A determined by its root set X?"

Lin Xiao glanced at a paper he took over and casually glanced at what he said. Well, it is indeed difficult, but it was for Chen Mingkai. He didn't think too much and gave the answer directly: " The root set object, and the problem itself must be discussed within the scope of geometry.”

Then he directly found a piece of paper and started writing.

"Let's give this form to define..."

[For the complex number field A, D: N-dimensional complex projective space, which is the total set of all complex straight lines passing through the origin in C^(N+1)]

"Each point above can use homogeneous coordinates [x0, x1xN], and then..."

[[x0, x1xN]*K, K≠0...]

"So we can think of them as the same point."

"Going back to your question just now...well, I've said it this far, you should understand, right?"

Chen Mingkai nodded repeatedly. Lin Xiao had already explained it in detail. If he didn't understand it anymore, he would be ashamed of his status as the first disciple of God Lin.

"I understand."

"Well, it's good that you understand. I just gave the simplest situation. Then you can try to describe it using mathematical logic and give an example." Lin Xiao immediately started to test his own students.

Chen Mingkai also knew that this was the first time that his great mentor would test himself, so he touched his chin and began to think. After a while, his eyes lit up and he replied: "About 0 of the homogeneous polynomial of x0xN The set G composed of points is our research object. The mapping between these objects described by a family of polynomials is a morphism. Well... for example, if there are two objects E and H, it is said that X and Y are isomorphic. In fact, it is equal to Valence has morphisms F:X-\u003eY, G:Y-\u003eX, so we can know that FG=ID, GF=ID.”

Lin Xiao nodded with satisfaction and praised: "Yes, that's a good answer. Your talent is still very good."

"Do you have any other questions?"

"Thank you Professor, I don't have it for now, leave it to the juniors."

After receiving the professor's praise, Chen Mingkai also showed a smile on his face. After speaking respectfully, he turned around and made way for his two junior brothers.

As a doctoral student, of course he has many questions. Of course, although there are many questions, it is also very necessary to conduct research on his own. Therefore, unless it is a problem that he has thought about for a long time and does not know how to solve, he will try to ask his supervisor, and other Yes, he needs to rely entirely on himself.

Next, Li Min started to ask. Li Min studies algebraic number theory.

"Why is the multiplication structure of the Z ring such that each non-zero integer can be expressed as a unique number of prime powers and ±1 multiplication?"

Being related to number theory is naturally Lin Xiao's strong point. When he heard this question, he said directly: "If you study this, I recommend you to read a book, "Algebraic-Number-Theory", Jurgen ·Newkirch's book, 1999, you can read the second volume in it and you will have a better understanding. I also recommend that you read this book."

Li Min was stunned, but he didn't expect Lin Xiao to give him a book title directly.

Admiring Lin Xiao's vast range of knowledge, he asked the next question.

In this process, Lin Xiao naturally showed the so-called Lin Shen's demeanor, basically answering all their questions. Almost all of their questions were answered directly without thinking.

In this way, the three students all received a careful explanation and returned to their seats to start research.

As for Lin Xiao, she picked up her phone and saw a message she received.

Zheng Ronger's parents, Zheng Cheng and Xu Yan, were successfully transferred back to the Beijing National Laboratory of Condensed Matter Physics because of the paper published in Science. To thank him, they wanted to treat him to a meal in the afternoon.

In response, Lin Xiao naturally sent a congratulations first, then thought for a moment that he had nothing to do, and said that he would go on time.

Then, he sat in his office and enjoyed this leisurely time with nothing to do.
