Chapter 330 Graduating early?
"Brother, don't say such ambiguous words, I'm afraid my girlfriend will misunderstand."
Xu Qingshan pushed Liu Ruochuan's shoulder in disgust.
Why is such a handsome guy with a high level of intellectuals so angry?
"Can you just say whether you can help me with this or not?"
Liu Ruochuan pushed the enamel porcelain on the table in the direction of Xu Qingshan, as if he would stay here if Xu Qingshan didn't agree.
"Help you, help you, but does Hodge's theory require any computing power?"
Xu Qingshan thought for a while, and he really didn't know much about Hodge's theory.
“Can the field of algebraic geometry not require computing power?”
After receiving Xu Qingshan’s reply, Liu Ruochuan sat down with satisfaction and began to play with the paperweight on Xu Qingshan’s desk. It was a Little lion, Xu Qingshan himself didn't know when this thing appeared on his desk. He just didn't know whether Tong Tong bought it or Jiang Huanxi bought it.
"In fact, you have found your way in number theory. If you don't really like it, who else will do number theory?"
Liu Ruochuan said, he seemed to have a little ADHD, and he took the little lion paperweight. After that, he casually took a pen and turned it around in his hand, and briefly expressed his thoughts to Xu Qingshan.
“Nowadays, the mainstream is either doing algebraic geometry or analysis, and number theory is the least beneficial.”
“I just did number theory first, it doesn’t mean that I only know how to do number theory. Look, when you come here, won’t I do algebraic geometry with you?”
Xu Qingshan said with a squinted smile.
"Tell me briefly about Hodge's theory. Let me have a rough idea. Since you are all here, I won't bother to find it myself."
"I'm going to Paris this time. It is just for studying Hodge. Currently, there are not many studies on p-adic Hodge theory in the international academic circles. They are mainly concentrated in Paris. , especially the Ecole Normale Supérieure in Paris. I have basically mastered everything I can master this time. If I don’t come back to see you, my next stop may be to go to North America.”
Liu Ruochuan knew. An efficient person like Xu Qingshan will definitely understand the topics he proposes as soon as possible.
"I have prepared it for you a long time ago. It is all here, including the first-hand information I recorded in Paris."
Senior Brother Liu took out a thick stack of documents from his briefcase The paper was divided into many copies. It looked very important and had dense handwriting on it.
"You should know that Hodge numbers are, in the study of complex algebraic varieties, the dimensions of the holomorphic Dubilt cohomology group, which can be regarded as an important extended concept of algebraic geometry."
"This I know that in terms of machine learning, deep learning is used to process algebraic topological data, especially on the complete intersection Calabiyu manifold 3 and 4 latitude manifolds, in order to better predict the Hodge number. ”
Xu Qingshan. nodded.
“Let’s give it something strong. I also know that the p-adic Hodge theory you are studying, brother, also played an important role in the proof of Fermat’s last theorem. Let’s give it a little more depth.”
< br>"Okay, actually, my current thinking about p-adic Hodge theory is not very complete, and I plan to take it in several steps. But now Hu, I mainly want to develop p-advantage analysis technology. Breakthrough, we can establish a Simpson functor for any local system of p-adic smooth rigid cluster God. The small condition made by Faltings before has limitations. If we can break through, we are very hopeful that p-adic can be moved forward. Advance a level, but when it comes to this, if p advances, then number theory will benefit, and won’t you be the one who benefits?”
As Liu Ruochuan spoke, he winked at Xu Qingshan again.
Xu Qingshan rolled his eyes at him speechlessly.
"What does it have to do with me as the number theory tools increase? I have already said that I may not continue to do number theory."
After Xu Qingshan finished speaking, he flipped through the documents and collected them. Go aside.
“Okay, let me finish reading these documents.”
Liu Ruochuan sat still, looking here and there, and flipping through the manuscript that Xu Qingshan had just written casually.
Xu Qingshan glanced at him, ignored him, and began to work on what he wanted to do at the beginning.
“You want to kill Diophantus?”
Liu Ruochuan asked with interest.
“Yeah.”
"Duffin-Schaeffer Conjecture?"
"Hmm."
"Add me one?"
"No."
"Add me one Well.”
"Look at our little Xue's eyes."
Xu Qingshan rolled his eyes at Liu Ruochuan.
"Xiao Xue? What Xiao Xue? Where are you from?"
Liu Ruochuan turned his head and met Xue Xuequing's pitiful eyes, like those of a little rabbit that had lost a carrot.
“I understand, then let’s just focus on p-advance.”
"Okay, senior brother, I will watch. Stop standing here. You see, these two students are not comfortable. If you sit here for a few more minutes, they will not even dare to think about graduation."
Although Xu Qingshan and Liu Ruochuan are sitting here and have higher status than Wang Wei and Xue Xuequing, in fact Liu Ruochuan is similar in age to these two girls.
"Oh, the feelings have faded. I was kicked out everywhere when I came back. It's so pitiful."
Liu Ruochuan pretended to stand up, but looked at Xu Qingshan.
He is quite good at playing tricks.
"Come on, you're back. Go and complete the onboarding procedures as soon as possible. Then I'll go to your office every day and sit and drink tea."
Xu Qingshan said without raising his head.
"I never said that I would join Beijing University. My goal is the stars and the sea. I want to go far away."
Liu Ruochuan was still arrogant.
Xu Qingshan ignored him and took out the letter of intent for talent signing that had just been mixed in the pile of papers and handed it to Liu Ruochuan.
"If there's nothing else, I'll leave first."
Liu Ruochuan looked down, took the document bag as if nothing had happened, and left the office without looking back.
"Pfft."
The two girls in the office couldn't help laughing after Liu Ruochuan left.
Xu Qingshan shook his head and continued busy with his own affairs.
Xu Qingshan didn't go to the canteen for lunch. Instead, he worked in the office and asked Xue Xuequing and Wang Wei to bring him a burrito for a quick snack while they went to eat.
When people focus on doing work they love, it is always easy to enter a state of flow.
“Teacher, let’s go first.”
Xu Qingshan raised his head only after hearing Xue Xuequing’s greeting.
“Well, go ahead and wait for me to close the door.”
Xu Qingshan watched the two girls' backs disappear within the door frame, and rubbed his temples tiredly.
It’s not that my brain power can’t keep up.
But it seems that he has not been doing this kind of in-depth purely academic research for a long time. Xu Qingshan feels that his state of mind is not very good.
The brain needs to be used frequently to be effective.
He slowly packed his things.
I stayed at Nanchizi last night, and I originally planned to finish early today and go back to Yandongyuan to tidy up the house.
If you need to commute every day when school starts, living in this apartment in Yandongyuan will be much more convenient than in Nanchizi.
Just when Xu Qingshan lowered his head to confirm that he had nothing to bring, he was about to get up from the chair.
The light seeping into the office from the door dimmed.
“It’s okay, I’ll just close the door.”
He thought it was Xue Xuequing and the others who were back again, so he said without raising his head.
“Are you so busy today?”
Hearing a familiar voice, Xu Qingshan suddenly raised his head.
Jiang Huanxi stood at the door with a tired look on her face, but she was not tall enough, and the light continued to seep into the room through the hair on her head. She looked like an angel with her own backlight.
"You're here? Why don't you go back and rest first?" Xu Qingshan looked at the thick and bloated handbag in Jiang Huanxi's hand and knew that she had spent a lot of time running procedures today.
"I thought you might not have gone back yet, so I came over to take a look. Anyway, it went well. You really haven't left yet."
Jiang Huanxi walked into the room and put the bag on the table. .
"Is the procedure for applying for day study so complicated? Do you need to take so many books?"
Xu Qingshan casually tried the weight of the bag and was a little surprised.
"That's why I brought your textbooks back by the way. The teacher said that you should be busy and don't need to do these things, so I brought them back to you by the way."
"Your procedures, I All the procedures have been taken care of. Today I am going to complete all the subjects for this semester. I’ve been to all the teachers, but several of them are absent. You don’t have to go to every class this semester.”
“Idiot, you don’t have to go there in the first place. Thank you very much.”
< br>Xu Qingshan rubbed Jiang Huanxi's little head helplessly and lovingly.
This silly girl followed the rules and worked her legs hard.
"Hug."
Jiang Huanxi held Xu Qingshan's hand and moved forward two steps. Her face was full of exhaustion and she did not respond to Xu Qingshan's words, like a little robot that needed to be recharged. He came closer, trying to recharge his batteries.
“I want a hug.”
Xu Qingshan moved a little slower, and Jiang Huanxi mumbled and emphasized.
Xu Qingshan's hand didn't use any strength at first, so Jiang Huanxi took advantage of the opportunity and got in, holding his waist tightly.
"Okay, hug. Let's go back in a while. We have to clean up later, otherwise it will be hard to have a good night's rest."
Xu Qingshan rubbed her hair down, making Jiang Huanxi's hair feel cold. Yes, it seems that I stayed outside for a long time.
After turning off the lights in the office and locking the door, Xu Qingshan took Jiang Huanxi's hand and walked downstairs.
It gets dark early in February.
Xu Qingshan took Jiang Huanxi's bag into his hands, still carrying the bag behind him.
However, his hand was firmly held by Jiang Huanxi and stuffed into her pocket. It was very warm and he could feel the touch in the pocket.
“You put a warm baby in your pocket?”
Xu Qingshan breathed a sigh of relief.
The street lights turned on, and among the figures flickering under the street lights, there was a pair that belonged to them.
“Yeah.”
Jiang Huanxi looked up at Xu Qingshan, narrowed his smiling eyes, and boasted.
"I'm smart, right? Isn't it very warm?"
"It's taped on the pocket, but not on the inside of your clothes?"
When they hugged each other just now, Jiang Huanxi was The zipper was opened, but perhaps Qingshan didn't see Nuan Baobao.
“No eh”
Jiang Huanxi's originally pleading expression suddenly fell.
“But I want your hands to be warmer.”
“We will buy more later, and we can even put them on the shoes.”
Xu Qingshan did not He denied Jiang Huanxi's intention and said with a smile.
“Hmm!”
"By the way, Qingshan."
Jiang Huanxi smiled, suddenly seemed to think of something, and was startled.
"What's wrong?"
"I almost forgot something important. Today the teacher asked me if you plan to graduate early this year. Dean Xu specifically told me, It's Academician Tian Gang from the School of Mathematics. I mentioned to her that if there is any, you can send a message to Dean Xu when you go back later, and the teacher will give you an exam form. If you get enough credits this semester, you can graduate early."
Jiang Huanxi said while looking at Xu Qingshan.
"Graduate early?"
Xu Qingshan thought for a while, this should be the reason why the Mathematical Institute arranged a professional title for himself.
By quickly completing an undergraduate degree and getting a doctorate, the school will be able to arrange more awards and funds for itself, and they can be included in the faculty and staff system.
"Okay, I'll ask Dean Xu when I get back."
"Well, maybe I can really study in your graduate school."
Jiang Huanxi's thoughts were running wild.
"Okay, isn't it done now? Which undergraduate student have you ever seen treated like you?"
Xu Qingshan smiled and let Jiang Huanxi pull him into trouble.
Back at the door of Yan Dongyuan’s familiar cabin, Xu Qingshan was about to take out the key and open the door, but the door opened with a click.
The lights in the room are on.
After the door was pushed open, a slender and graceful girl stood behind the door, looking at Xu Qingshan and the others expressionlessly.
"It's getting dark, come in."
Like the owner of the house, Tong Tong greeted Xu Qingshan and the others to come in, but her eyes briefly stayed on Xu Qingshan The hand that was stretched out in Jiang Huanxi's pocket took it back for a moment.
"Did you end it so early?"
After entering the room, Xu Qingshan asked curiously.
Usually the training time for the competitive training team is later, and there are evening self-studies in the evening.
"Well, I got perfect marks in the post-holiday status evaluation test today, so the training coach asked me to make my own arrangements."
Tong Tong curled his lips.
Xu Qingshan was still a little curious about what happened to her. When he entered the house, he found that the entire Yandongyuan house had been cleaned, which was better than paying for cleaning.
Looking at the bucket in the bathroom and the brooms and mops that were being dried after washing, he knew that this must be Tong Tong's handiwork.
Tong Tong shook his head towards the house.
"I've also changed the sheets and quilts in your room for you."
"Thank you, kid."
This made Jiang Huanxi a little embarrassed.
Tong Tong was very busy at home. He took Xu Qingshan for a walk outside and used it with Xu Qingshan when he came back in the evening
Although the positions are different, no matter how I think about it, I feel that Tong Tong is a bit pitiful.
"It's nothing, call me if you need anything. I went to the room to do the questions."
Tong Tong was about to go back to the room, but was pulled back by Xu Qingshan.
"Wait, little boy, this is for you."
Xu Qingshan handed the enamel porcelain gift box Liu Ruochuan gave him to Tong Tong.
"My senior brother brought it back from Paris. I think you will like it."
Tong Tong's first reaction was to look at Jiang Huanxi before taking the thing, her emotions written on her face , cloudy and sunny in an instant.
"I just marinated some chicken. I will make Orleans chicken for you after I finish the questions tonight."
"Okay, I will ask Brother Chuan to arrange a few cups of fruit tea."
Xu Qingshan said with a smile.
However, Jiang Huanxi's eyes seemed slightly resentful again.
Tong Tong returned to the room, and Xu Qingshan and the others also entered the room. When taking off his down jacket, Jiang Huanxi thought for a while to make her voice less sour, but before she could speak , but Xu Qingshan spoke first.
"Senior brother came to me to do a project on p-adic Hopper theory. I would like you to work with me on this project?"
