Scholar's Cultivation System Panel

Tang Yanshan looked at the draft paper in his hand, and his facial expression gradually became solemn and serious. After about half a minute of touching, he raised his eyes to look at Xu Yun and asked about the situation of this question.

"How did you start studying algebraic geometry?"

"I'm studying abstract algebra recently, and I want to understand the concept of algebraic geometry when I came across it by chance."

With a simple and honest smile on Xu Yun's face, he met Tang Yanshan's eyes and answered in a deep voice.

It is impossible for him to bluntly say that he wants to prove Hodge's conjecture, which is still far away from his current level of mathematics.

This explanation is undoubtedly more appropriate.

Tang Yanshan has checked Xu Yun's final grades and knows that he has mastered the professional courses of the sophomore stage very well, and it is quite normal to start studying the contents of the junior year now. It just so happens that he will be more confident in winning the trophy when he participates in the Higher Education Society Cup return.

Abstract algebra belongs to the junior textbook, but algebraic geometry is more complicated to understand.

You will not be exposed to study until you are admitted to a graduate student.

Xu Yun didn't have a thorough understanding of abstract algebra, so he thought that studying algebraic geometry would inevitably make some mistakes in decision-making.

How can I run fast without thinking about learning to walk.

The more talented a person is, the more they must be steady and steady, and master every basic knowledge thoroughly.

It was precisely because he was worried about this that he asked Xu Yun specifically to make sure that the other party did not have the problem of chewing too much.

After hearing Xu Yun's answer, he hesitated a little and decided to talk about it.

Then he stood up, picked up a piece of chalk with his thumb and index finger, and wrote the argumentation process of this question facing the blackboard.

Xu Yun stared intently, for fear of missing any step.

The most important thing in the process of learning algebra is to combine the image and the equation. The image is regarded as a collection of all points satisfying a specific equation on the coordinate plane, that is, all solutions of the equation are assembled on the coordinate plane, and the equation is regarded as an abstract description of the image. .

But in algebraic geometry, there are countless polynomials and images like this.

at the same time.

The graduate students in the audience were also attracted by the content on the blackboard, and they all confirmed what Tang Yanshan was writing.

"What Professor Tang wrote looks so complicated."

"Seems like a proof in algebraic geometry."

"This guy is too monstrous. Have you started studying algebraic geometry as a freshman?"

"I must be a fake graduate student. I can't understand Professor Tang's writing process."

"Where did he find the question?"

Tang Yanshan didn't care about his graduate students. After writing the whole proof process, he turned around and explained it to Xu Yun. During the process, he asked two related extended questions from time to time.

After Xu Yun's own ability has been greatly improved, what he is best at is understanding problems.

Therefore, after listening to Tang Yanshan's explanation, he suddenly understood and answered all the questions fluently.

After finishing speaking, Tang Yanshan asked with a smile, "Do you understand?"

"Understood." Xu Yun nodded.

Hearing this, a gratified smile appeared on Tang Yanshan's face.

If it was when he first came into contact with Xu Yun, he might reply that you know nothing.

But now he is very clear about Xu Yun's strength and character, since he said he understood, there must be no problem.

It’s just that those graduate students were miserable. After listening to Tang Yanshan’s explanation, their faces were still blank, obviously they didn’t understand at all. Although they wanted Tang Yanshan to explain it to them again, they couldn’t say it. exit. After all, the people who asked the question had already understood it, so they had the nerve to speak up to embarrass Tang Yanshan.

Tang Yanshan didn't wipe the formula on the blackboard, and then he thought of something and told Xu Yun a few words.

"I know you are very talented in mathematics, but right now you still need to learn abstract algebraic real variable functions and functional analysis well, and it's not too late to get in touch with algebraic geometry in the future."

"Don't worry, Professor Tang, I will make a plan." Xu Yun replied following Tang Yanshan's words.

The matter was basically over here, but Tang Yanshan noticed that Xu Yun had no intention of leaving, so he picked up the cup and took a sip of tea to moisturize his throat.

"What else is there for you?"

"Professor Tang, can you recommend me some textbooks related to topology?"

Xu Yun stated his purpose with a guilty conscience.

When Tang Yanshan heard these words, his expression immediately turned down.

Just now I said that I can plan well, but the problems of algebraic geometry have not been completely solved, and now I have to touch topology again.

I really think that I have forty-eight hours a day.

"You boy..."

He was about to teach aloud, but he stopped suddenly after saying three words.

Then he waved his hand and answered.

"never mind."

"With your character, even if you are not allowed to learn it, you will definitely get in touch with it in private."

"Let me recommend some suitable textbooks for you."

"At least in this way, we can avoid detours."

While speaking, he took out a pen from his pocket and wrote the names of several textbooks on the draft paper.

"These textbooks can be found in the school library. In short, remember to arrange your time reasonably." Tang Yanshan put away the pen and handed the draft paper to Xu Yun in front of him again.

"Thank you, Professor Tang." Xu Yun felt as if he had found a treasure, and quickly thanked him after taking it.

Coincidentally, the bell for the end of get out of class rang at the same time, and Tang Yanshan began to pack his things and prepare to leave. Obviously, he had other things to do later.

Soon after Tang Yanshan and Xu Yun left the Q\u0026A room one after another, the graduate students immediately got up and went to the blackboard.

Discuss with a large number of formulas on the blackboard.

"This student doesn't know where to find the questions, but it's quite classic and interesting."

"Whoever understands it will talk about it, I still don't understand it."

"If I knew I should have asked Professor Tang to explain it twice, I really regret it."

"That junior, do you think he really understands or pretends to understand?"

"I understand a little bit."

As one of the tall boys raised his hand to signal, everyone quickly shifted their attention and took out their notebooks or directly turned on their mobile phone cameras to ask the other party to repeat the story.

The learning atmosphere is even stronger than the class just now.

Tang Yanshan didn't know what happened in the Q\u0026A room at this time, he saw Xu Yun waiting there just as he walked to the stairs.

He paused for a moment and asked, "If you have anything else to do, why don't you tell me all about it."

"I'm waiting to go to the history department."

Knowing that Tang Yanshan was going to pick up his lover from the Department of History, Xu Yun couldn't afford to waste too much time.

With a smile on his face, he immediately cut to the chase.

"Yes, there is still a little thing."

"I know you won't send me things for no reason, just tell me if you have anything to say." Tang Yanshan smiled when he heard this sentence, as if he had already guessed the situation, but after the previous words, he added: " First of all, if you can do it, I will definitely help you, but if you can’t do it, it’s useless to go to Dean Qin.”

"This is Professor Tang, I want to join the research group in our department to participate in project research."

Xu Yun didn't hesitate this time, and looked at Tang Yanshan's expression after telling his real purpose.

In order to complete the task task group, he must enter, even if it is only for learning and familiarization.

However, after noticing Tang Yanshan's dignified face, his mood sank immediately and he realized that this matter might be ruined.

Just as he was about to respond, Tang Yanshan's voice rang out first.

"You want to prepare for the Higher Education Society Cup?"

Before Xu Yun could answer this question, he went on to say: "Mathematical modeling is different from real subject research. If you have experience in this field, it is indeed more friendly to you during the competition."

"Let me help you pay attention first."

Xu Yun didn't expect that Tang Yanshan would think of the Higher Education Club Cup, but seeing the hope of things, he naturally wouldn't worry about it.

I quickly expressed my gratitude from the bottom of my heart: "Thank you, Professor Tang."

"Don't thank me in a hurry, it's not sure if it will be successful." Tang Yanshan waved his hands with a light smile.

Due to the distance between the mathematics department and the history department, Tang Yanshan did not talk with Xu Yun for too long.

Then leave in a hurry.

Xu Yun came back from the Q\u0026A room, and returned to an extremely regular life in the next few days.

Apart from listening to lectures on professional courses such as abstract algebraic real variable functions and functional analysis, most of the rest of the time is spent in the library studying algebraic geometry and topology.

Combined with the Hodge conjecture proof process in my mind, I can understand it a little bit.

Of course, it is still far from understanding.

According to Meng Songyan's report, the company has already contacted mobile phone manufacturers hoping to establish cooperation.

However, entering a brand new market, it is obviously possible to go completely smoothly in the initial stage.

Fortunately, the company is supported by the surveillance image optimization business, and can negotiate several cities every month, and has always maintained a large amount of cash flowing into the company.

Among them, Pingzhou City belongs to the earlier batch.

Soon time entered March, the temperature began to rise, and the scenery on the campus became more vibrant.

"Brother Dong, you really want to sign up for the spring sports meeting. I've never seen you run before."

In the dormitory at noon, Zhao Yuefeng talked to Qian Yudong while eating, with obvious worry and disbelief in his tone.

Jingzhou University holds a sports meeting every spring, and each dormitory is required to send personnel to participate. Under normal circumstances, people like Qian Yudong who don't like sports should stay away. In the end, as the head of the dormitory, he took up the responsibility for others with righteous dignity, and decisively signed up for the two events of sprint and high jump.

This operation can be said to have stunned the other people in the dormitory.

"I think Xu Yun is quite suitable to participate. He often runs in the morning to exercise." Zhou Qi fastened the food bag after eating, and raised his mouth after the conversation.

As soon as the voice fell, Qian Yudong's voice came from the dormitory: "Xu Yun is so busy studying every day, how can he be distracted by this kind of thing, let me, the head of the house, fight this difficulty alone."

The combination of voice and emotion is really touching.

But at this moment Zhao Yuefeng suddenly thought of something, put down his chopsticks, turned around and asked a question.

"I heard that this year's sports meeting not only has many girls' events, but also many colleges have specially organized cheerleading teams."

"Sheriff."

"Isn't it because of this that you..."

"Fengzi, you let me down too much. Is the head of the house the kind of person who values ​​sex and despises friends?" Qian Yudong ignored the smirk on Zhao Yuefeng's face, and still maintained his image in a serious manner.

Xu Yun was about to answer yes when he heard the words, but was attracted by the lit phone screen on the desktop, and looked away to see that it was Tang Yanshan's call.

Thank you Qin Siwang for the reward of 500 points!
