Chapter 1445

"Jinling University station is here. Please take your belongings with you and get off in order..."

The sound of reminders from the top of the head wakes the boat from its memories of the past.

At the same time, the live navigation system opened by the holographic glasses also printed with the pop-up window of arrival reminder.

Turning off the holographic panel suspended in front of him, the boat stood up from the seat, and with the flow of people moving towards the outside of the car, stepped on the place where he had once splashed his youth with excitement and uneasiness.

However, when he stepped out of the station and the sun was shining on his face, the whole person of the boat was stunned.

Here

What is it?

is completely different from Jinling University in memory. Familiar with the Wutong trail, there is a drone on the lawn. The silver white buildings on both sides can not see what functions it is, and even the shape of the teaching building has changed.

Pushing the AR glasses on the bridge of the nose, the boat set up labels for several experimental buildings, but the navigation cursor in front of it was divided into three different paths.

Three experimental buildings?!

Seeing the feedback from the navigation system, the ship was shocked.

When did the math department get so rich?

At the same time, the boat was in trouble. When he didn't know where to go, he was suddenly hit on his back.

Although it was an unexpected collision, there was nothing wrong with the boat itself, but the man who hit him almost fell to the ground.

"I'm sorry. I'm in a hurry!"

Picked up the glasses from the ground, the boy who accidentally hit him on the back made a quick compensation to him, and then he was about to leave.

However, where can Lu Zhou miss this opportunity? He is looking for someone to ask for directions. He quickly grabbed the boy's arm.

"Wait a minute, students. How can I get to the school?"

"Several hospitals?" The boy looked at Lu Zhou and asked, "which major?"

I was asked a question like this, and I blurted out subconsciously.

"Number theory..."

Listening to the number theory, the boy wearing the square glasses suddenly came back to his senses and held the hand of the boat tragically.

"Wocao, I also said which hospital's elder brother you are so slow, especially our hospital's! Do you dare to dawdle in the face paralysis class? Don't you want credits? "

Facial paralysis?

The boat was stunned for a moment, but it didn't know what it was, so it was pulled to run.

"Wait, wait a minute."

"What are you waiting for? Hurry up!"

"I mean Is there no more convenient means of transportation? "

"What else do you want to do at school? Drive over? Cough You guy's physical strength is OK. You don't need to breathe when running. I'm special Special Do it! Don't talk to me. "

Lu Zhou: "..."

This is not special is that you have been talking?

But your physique, just ran a few steps to become such, it's too bad.

When Lu Zhou came back to his senses, he had been taken to the teaching building by this talkative young man. He guessed the bell and stepped into a ladder classroom with U-shaped seats.

I found a seat in the back row and sat down, looked around the classroom boat, looked at the exhausted student beside me, asked with interest.

"This kind of big class is usually not named, right?"

Are the students in this era so diligent?

"Roll call? What is that... "

Looking at the young man's face, Lu Zhou immediately guessed that he had committed "frozen social difference syndrome" again, so he quickly changed his mouth and said.

"What's your name."

"Zhang Tao!"

"Which one is on that stage?"

"Professor Sun Jingwen..." For a moment, his eyes were staring at Lao yuan. Zhang Tao couldn't believe looking at Lu Zhou and said, "I'll go. You can meet me Don't even know him? "

Hearing this stupid question, Lu Zhou smiled sheepishly.

Seeing that the young man was quite interesting, he said with a smooth tongue.

"Guess why I never ask for a business card at every academic meeting?"

Zhang Tao squinted at him.

Every time

At your age, can you rub twice in the sky?

But he didn't tear it down, so he perfunctorized it.

"Why..."

Without paying attention to the perfunctory tone, Lu Zhou sighed softly.

"Because I'm blind."

What do you say?

There are many people he doesn't know. Anyway, everyone knows him.

However, the boy obviously listened to his words as a joke, covered his stomach with a puff, convulsed for a long time, and then straightened up uneasily."Cough Man, you are so funny. I almost didn't catch my breath. Shall we exchange a virtual community account? It's not boring to brush the planet Ben of the Kalan empire with you when you are free. "

With a smile of mystery, Lu Zhou didn't answer the question positively, but pointed to the direction of the podium.

"At first, let's listen to the lecture well. Let's talk about other things after class."

On stage.

A man with boundless glasses, plain formal dress and meticulous expression came to the platform.

The index finger knocked twice in the multimedia lecture, a circle of digital cracks spread around, and four white boards were arranged on the wall.

At last, Lu Zhou knew why this guy was called facial paralysis by the students, because his expression was not very rich. The facial muscles fell into dormancy as if to save energy. Since entering the classroom, the expression on his face has not changed at all.

"Today 's content may have some hyperdimensions, involving the most difficult problem in the field of mathematics at present, that is, whether all the nontrivial zeros of Dirichlet L function are located on the straight line of complex plane Re (s) =12."

"If you have previewed your lessons, you should be familiar with this problem. This proposition is a generalization question put forward by academician Lu at the 2022 International Congress of mathematicians in St. Petersburg. It is often called the generalized Riemann conjecture, and it is also a question that I have studied. "

"My teaching philosophy has always been the same. Mathematics is a discipline honed in practice. Without thinking about it, what I teach you will never become your thing."

"Try to listen to what you can understand, and record what you can't understand. Go back and think slowly."

As he said this, he turned to face the first whiteboard in a kind of students' groaning, and wrote a line of formula on it.

Zhang Tao, who was sitting next to the boat, frowned painfully, but the boat was familiar with it.

This thing

He's like a blackboard at the mathematicians' conference in St. Petersburg?

"The infinite series in Euler product formula is replaced by complex index s, and then when re (s) ＞ 1, Dirichlet l function is introduced Interesting. "

Listening to the whisper in the mouth of the big brother sitting next to him, Zhang Tao was shocked.

Can anyone understand this?

he just plans to make complaints about anonymous communities in his school, where he can write some bird language that he can only read.

"Can you read what he wrote?"

The boat came back to the road.

"That's right."

Zhang Tao asked tentatively.

"Group Group construction method? "

"What are you talking about?" Lu Zhou glanced at him lightly. "The part after introducing Dirichlet l function, of course, is the unified theory of algebraic geometry. Have you ever seen such a group construction method?"

The problem is that I haven't seen the unified theory of Algebraic Geometry

Realizing his ignorance, Zhang Tao closed his mouth with shame on his face.

The boat sighed softly, and went on with a flat head.

“…… It's just as well. In my impression, few people can understand this theory to this extent. It's just that the usage is rigid. The old way doesn't always care. It's better to make some modifications. "

Hearing this, Zhang Tao's face immediately became more ashamed.

Ma ye, it's also pretending to be forced. Why is it pretending to be so fresh and refined, mellow and natural, not red in face, not jumping and shaking in hand?

The key is that I almost believe it.

What a talent!

In a distracted time, Professor Sun Jingwen, who has written all over the whiteboard on the stage, seems to forget that he is in the classroom and focuses on the immediate problems.

However, he seems to be in a little trouble, standing there with his eyebrows locked, as if he is in trouble.

In fact, he did get into trouble, at least in the eyes of the land boat.

If no one reminds him, I'm afraid that if he wants to go tomorrow, he can't think of a reason.

It's very clear that this feeling of getting into the ox horn. The boat sighed gently. Just when he hesitated to help this guy, his eyes suddenly fell on the red button at the corner of the table.

There was a trace of curiosity in his eyes. Lu Zhou touched Zhang Tao, who was sitting next to him, with his index finger, and pointed to the button.

"What is this?"

"Instead of raising one's hand, there will be a big classroom like this."

"I see."

He nodded thoughtfully, and then the boat reached out and pressed the button.

I thought there would be red lights flashing, or sound effects of prompts and so on. As a result, there was nothing.

However, the land boat soon saw that a pair of eyes saw him, which was more noticeable than shouting with a big horn.Staring at the boat that pushed the button, Zhang Tao, who was sitting next to him, was so shocked that he quickly pulled his cuff.

"Lying trough You don't want to live? "

In the Mathematics Department of Jinling University, everyone knows that facial paralysis is the most annoying thing that others interrupt his thinking.

Especially when his research is at a critical stage

Interrupting him at this time to ask questions is no different from looking for death.

Zhang Tao's voice became weaker and weaker at the end, because just as he was speaking, a sharp line of vision had been shot from the platform

Pushing the rimless eyes, Professor Sun Jingwen looked at Lu Zhou expressively.

"You have a problem?"

"No," he said, rising from his seat, shaking his head slightly and laughing, "it's you."

At the moment when the voice fell, a loud voice spread in the classroom.

A group of students' faces showed or unbelievable expressions one after another. They looked at Lu Zhou and sun Jingwen standing in front of the platform.

What's the difference between this tactless way of speaking and death?

Many even gloated on their faces, waiting for Professor Sun's next reaction.

However, a strange scene happened.

I saw Professor Sun standing on the stage was not as angry as most people expected, just frowned.

“…… What's the problem? "

Lu Zhou: "corollary 4 of line 24, it's OK for you to introduce differential manifold here, but I think l manifold When academician Lu designed it, he didn't think it would be used to solve the problem of Dirichlet l function. "

"Of course I know," Sun Jingwen pushed his glasses and stared at the face of Lu Zhou, trying to see more clearly, but still didn't recognize where the strange face came from. "The L manifold is the key he prepared for solving the NS equation problem, not used to solve the Dirichlet l function problem, but as one of the key elements to solve the Riemann conjecture, it serves as a surrogate It is also undeniable that this is the core tool of the unified theory of numerical geometry. "

"Your research on the history of mathematics is good, but after all, it's not archaeology," Lu Zhou said with a smile and a gentle voice. "Can you borrow a whiteboard to talk?"

It seems that Professor Sun Jingwen was stunned. Unexpectedly, the student came here.

But he didn't say anything, just nodded his head expressionless and made a gesture of asking at will.

"Please."
