Chapter 344 The four directions given by Xu Qingshan
Xu Qingshan entered the school and walked towards the small building of the Institute of Mathematics as usual. It was not until he was almost entering the gate that he remembered that he had moved to a new laboratory, and then turned around and headed towards his own building. .
Before he went upstairs, downstairs, Xu Qingshan was stunned for a moment when he saw the corridor.
The four rooms in this small building are arranged flat. The design of the building is somewhat like a teaching building in a primary and secondary school. People who are slightly taller can see the doors and windows upstairs from downstairs.
At this time, Xu Qingshan was standing downstairs and had already seen the colorful graffiti with a strong visual impact in the corridor upstairs.
However, this culture that seems to be closer to the streets is now expressed in the corridors with colorful mathematical, physical, computer and other formulas, concrete objects, and various proper nouns.
When these square words and words, which were usually only seen in mathematics monographs and papers, appeared on the wall in a trendy way, Xu Qingshan felt an unprecedented pleasure.
Obviously, this must have been done by that guy Xue Xuequing. To be able to come up with such a creative thing in one day, she really shouldn't be studying mathematics. She should be studying art.
Xu Qingshan is certain that it won’t be long before his laboratory will become an on-campus attraction of Beijing University. He doesn’t know how busy it will be during the visiting season in July and August.
Going upstairs, Xu Qingshan's eyes lit up even more.
The corridor is no longer dusty as it was yesterday and has been swept clean. Although it is just a cement floor, it is so bright that it seems to reflect light. He also looked at it when the school cleaning came to deal with it yesterday. It did not achieve such an effect. It should be two What did the girl do to herself?
And that kind of eye-catching "academic" graffiti is not only found on the door walls of the corridors, but also on the inside of the low walls of the corridor handrails that are rarely noticed.
The curtains in the room have all been replaced and replaced with new thick and contrasting curtains with high enough light shading. The colors are bright but not gaudy. They seem to make people feel more relaxed when their eyes move upward.
Xu Qingshan looked at the layout of the first large room. Although Wang Wei and Xue Xuequing had not arranged many details due to the short time, the staggered independent workstations were arranged in an orderly manner and did not disturb each other. It just looks great.
In the center of the room, there was a small wooden platform, which looked stylish. Xu Qingshan felt funny when he thought about having Liu Ruochuan stand on this small wooden platform and point at the curtain behind him.
"Director, are you here?"
After hearing the noise coming from Xu Qingshan, two little heads popped up from the farthest corner of the room.
Wang Wei and Xue Xuequing came to the laboratory early in the morning to set up the laboratory. Although moving to a new site was a bit tiring, they were also full of satisfaction watching the process of building this small shabby room from scratch.
Although they received news from Xu Qingshan last night, the two of them returned to the student apartment very late, because the novelty of doing soft decoration design had not worn off yet.
"Yes, you two are very powerful. This efficiency is too high. Don't be tired. Take a rest when you need it."
Xu Qingshan was very satisfied, praised him, and expressed concern.
“Not tiring, very interesting.”
Xue Xuequing said with bright eyes. You must know that graffiti outside the school will be caught by the urban management, let alone inside the school. That is to say, Xu Qingshan, a young and enlightened mentor, can allow her to develop freely in her own territory.
For this reason alone, Xue Xuequing secretly decided not to go abroad after graduating from her doctorate. Instead, she would just stay with Director Xu as a postdoc. If she could stay in school as a researcher or a green pepper, she would be satisfied as long as she could stay with Xu Qingshan.
However, I don’t know if it would be less restrictive if it was Director Xu’s Ph.D., such as the mandatory requirement of studying abroad for two years for some research positions.
"I'm a little pressed for time, and I haven't purchased many things yet. I went to the furniture store this afternoon to have a look. The boss gave me the budget, and I spent it yesterday."
Wang Wei was wearing glasses and holding a small book in his hand. He was about to tell Xu Qingshan about yesterday's expenses, but Xu Qingshan raised his hand to stop him.
"Hey, use the budget if it's given to you. If it's not enough, just tell me. If there's any leftover, we can keep it as our own team building funds. Since you are the senior sister, I will leave all the big and small things in the laboratory to you. If you don’t understand, just ask me and you, Director Liu, Xiao Xue should give your senior sister more help.”
Xu Qingshan said with a smile.
Judging from the changes in this building, it can be seen that letting Wang Kai take over the management of the student level was the right decision. The two students Lao Zong gave him were surprisingly useful and reliable.
"Oh, okay."
Wang Wei nodded, turned over two pages expressionlessly, and continued.
"Ours is a mathematics laboratory. I have learned about the information science laboratory next door. Maybe a professional team needs to be hired for interior design. I will go and find out about it. If you can arrange some information science laboratories for me, It would be better if the teacher of the school, or the teacher of the electronic information maintenance department of the school, asked me to consult.”
"The third room has been cleaned, but it's still unclear how many researchers we will have. It was first divided into four partitions, and four sets of desks and chairs were placed in it. Then we changed the last office into a suite. The entrance leads to the public area, and the windows on both sides lead you to the office.”
Wang Weiyan briefly and comprehensively put forward his needs and the progress of completing the task.
Xu Qingshan nodded with satisfaction.
"Just arrange it at your own pace. Once I'm done with my work these days, when I come back from Ice City, we'll talk about the direction you're interested in. After deciding on the direction, I'll tell you about some topics worth paying attention to."< br>
Xu Qingshan casually mentioned.
Xue Xuequing on the side was a little envious, but then she thought about it. She had already obtained her research direction earlier. Recently, she had been working very hard to update her knowledge about Diophantus. From time to time, she would ask Xu Qingshan for some papers to study in depth. .
She has discovered that although her mentor is young, he is a super treasure boy.
Perhaps there is still some shortcomings in the breadth of the entire field, but in terms of the special precision that he has studied, he has accumulation and depth that ordinary people cannot match. It seems that he has super retrieval ability and system extraction ability, which is easily ignored. Ability that is crucial to academic research.
"I have a direction, teacher. After recently reorganizing your work on the twin prime conjecture, I have a good feeling that what you used in the analysis process should come from the automorphic L function, the sieve method, and the new circle method. , I am now basically sure that my subsequent core work during the Ph.D. stage will be in analytic number theory. At present, it is probably the best route for me to pursue. I just follow your route to complete the supplementary analysis of the twin prime conjecture, and supplement and improve the methods you used on algebraic geometry, geometric topology, and the new sieve method, but I hope that I can complete it within the academic limit. Two articles, the teacher may give me some suggestions for the work topic of the other article.”
Wang Wei, a girl who doesn't usually talk much, seemed to be too immersed in the state after receiving the position of senior sister bestowed by Xu Qingshan.
This kind of speech full of rationality and self-improvement ideas surprised Xu Qingshan even more.
Why does Xiao Wang feel that he has quietly evolved in a day or two?
He couldn't help but glance at Xue Xuequing, who had an equally surprised face next to him. Xue Xuequing happened to look at Xu Qingshan, and looked at the sky and the earth with a guilty conscience.
Anyway, no wonder the senior sister is Wang Wei, and Xiao Xue can't compete with Xiao Wang, right?
"Yes, your idea is very clear. As for analytic number theory, some people have been saying that analytic number theory has come to an end. Last time, some people said that after I solved the twin prime conjecture, it was the final swan song in the field of analytic number theory."
Xu Qingshan said with a slight smile on his face. "Although my current work is mostly extended in other directions, I can tell you clearly that analytic number theory still has a bright future, and there are many directions and topics that can be tackled."
"With the progress of the times, analytic number theory has actually been developing. It is not just big problems such as Riemann Hypothesis and Langlands Program. So, now that you have thought so clearly, I will give you a few directions. Recently, this You can learn more about it in some time and finally tell me your decision.”
Xu Qingshan stretched out his palm and opened his fingers to count the topics he gave Wang Wei.
"The first one is the automorphic L function you mentioned. In the process of doing it, I actually paid attention to the subconvex boundary problem of the automorphic L function. This issue is actually quite core. To study the practical application of L function The upper bound is estimated to be 1/2. ”
"The second one is the relationship between the prime number distribution of the Möbius function. I remember Terence Tao seems to be paying attention to this recently. He will update his latest work status on his blog from time to time. As a person who just got the Fields degree a few years ago, I am not being modest about being a great person who has won many awards and Ultraman Awards. The breadth and inspiration of his work are much higher than mine now.”
Xu Qingshan paused, perhaps thinking about the possible directions for the second topic he gave Wang Wei, and a few words naturally popped into his head.
"Well, you can try to find a method for the Möbius orthogonality conjecture and try to understand the oblique product."
Xu Qingshan quickly provided the ideas he had mastered without reservation, and Wang Wei also vigorously wrote down in his small notebook.
Only Xue Xuequing stood beside him in a daze like Bajie.
"Then the third one is the arithmetic properties of algebraic varieties in projective space. You can incorporate my algebraic geometry solution method to invert how to calculate the rational points of algebraic varieties, such as Manin's conjecture and Birch's theorem."
Read the error-free version at 69 Book Bar! 6=9+Book_Bar debuts this novel.
"Fourth, as you said, the new form of the circle method I used is actually from more than ten years ago. You can read Wiles Brown's "Anew form of the circle method", which introduces Kloosterman to solve problems related to the quadratic form. It is very useful when doing it. It will not be limited to the original circular path and can be done in depth. ”
"That's pretty much it."
Xu Qingshan thought for a while and then added.
"If you want to do analytic number theory, or if you want to do it in depth, go further, and be more distinctive, you can't just do analytic number theory. For example, the Möbius conjecture is linked to dynamical systems and partial differentials at the intersection of physics. Projective space algebraic varieties are directly the background of algebraic geometry, and even those of harmonic analysis can be integrated into analytic number theory to develop larger spaces. ”
"Combine your points of interest and find your entry point, and you will succeed."
Xu Qingshan patted Wang Wei on the shoulder, nodded to Xue Xuequing, and left the mathematics laboratory, eager to see his independent office.
Originally, he was still thinking that if he stayed in the same office as Liu Ruochuan every day, he would one day be teased by this senior brother who liked oral sex and have a full-scale martial arts show in the office.
Now I can feel relieved.
Entering the office, Xu Qingshan was very satisfied at first glance.
This separated suite is actually a bit similar to the layout of the previous one at the Institute of Mathematics. Although these large and small buildings in Beijing University are a bit old and have not been renovated, they are kept clean by the two girls.
And also considering that the two family members of Xu Qingshan's family often came to the laboratory to put the work stations, this person must not be worried, so he placed two work stations in Xu Qingshan's office specifically for those two. Bit use.
It's just a slight tweak to the layout.
Xu Qingshan's desk was moved forward and turned into a large L-shaped desk. The huge bookcase moved from the Institute of Mathematics was behind the desk. It served as the background wall for Xu Qingshan's heart-to-heart talks with students and researchers. This bookcase wall is used as a partition, with two workstations and a single iron frame bed reserved inside, which can be regarded as making full use of the space.
"Yoho, why is your office so compact? It's not like mine, which is open and bright."
Xu Qingshan was just thinking about what he could put in the room. Liu Ruochuan just saw him coming out of the office and came over to say hello and say hello.
The bookcases in his room were placed against the wall, and the only thing in the room was the desk and sofa. The light coming in from the window completely filled the room.
"Because I often have family members coming to visit, unlike you."
Xu Qingshan said half of it, and deliberately looked at Liu Ruochuan with pity.
Liu Ruochuan suddenly said "Oh".
"No, no, no, I won't talk to you anymore. That look in your eyes makes me feel so pitiful. You were still wearing diapers when I was in love."
Liu Ruochuan said harshly.
"Tsk, you're still being stubborn."
Xu Qingshan smiled contemptuously, and Liu Ruochuan was defeated.
"Speaking of which, how are you going to arrange your students at Xinke? I can't help you with the researchers and students at Xinke. You'd better find a deputy to help you manage Xinke."
Liu Ruochuan suggested.
He has now begun interviewing candidates, and hopes that many senior scholars and young scholars can join Xu Qingshan's team.
Everyone is engaged in scientific research. It is unclear what level Xu Qingshan is and whether he can produce results.
"Well, okay, I will just find the Meiyuan of the Academy of Information Science and Technology when the time comes."
Xu Qingshan said and suddenly paused.
"Actually, it's not necessary. Our school didn't say that researchers at the Institute of Information Science and Technology cannot recruit foreigners. I went to the Information Technology Center in a few days and almost forgot the person there."
Xu Qingshan laughed, but Liu Ruochuan didn't know why. He shrugged and went back to his office.
He also needs to think about how to design his own office.
If nothing else, Liu Ruochuan will use this office for a long time.
Xu Qingshan, on the other hand, has already begun to think about who he can recruit from Professor Davis and the others.
