Chapter 496

"It's coming, it's coming, Brother Chu is here again!"

"Good morning Brother Chu, he's still as handsome as ever!"

"It's the third day, isn't it? Brother Chu is going to live here?"

"Why don't you say buy it?"

"Brother Chu likes to come to the library, I like to come to the library, so, I am equal to Brother Chu!"

"You're the one the logic ghost is talking about, right?"

Listening to the voices of the students around me, these people are all close to the graduate school entrance examination, and they came here early in the morning to line up, but there are a lot of first-year students today.

Someone greeted him, and Chu Yun also smiled and nodded in response.

He thought that he would not come to the library this afternoon because he was going to finish his research in the laboratory in the morning.

But when he thought about it, he didn't understand something, and he was ready to figure it out.

Perhaps, from the two properties of functional to number theory, Chu Yun wanted to figure out the effective relationship between them by combining mathematical physics.

However, he only had one morning to calculate, and in the afternoon he had to take into account the two hours of the final study.

After all, today is also the first day of the broadcast of the National Treasure Live Platform, and he, the boss, will also be there.

Besides, as a complete entrepreneur, Chu Yun didn't want to immerse himself in the laboratory and library every day, and occasionally have to go out for a walk.

Of course, I saved time, and this time he brought his notebook with him.

Chu Yun originally wanted to stay on the fifth floor, but unfortunately there were many people, and after Chu Yun found the information he wanted to see, he returned to the first floor.

With a book and notebook in hand, Chu Yun sat in the old place where he sat for the first time.

But next to this, there was a delicate-looking, but very quiet girl.

This person Chu Yun has the impression that it was Lan Xiaowan who asked questions during his lecture.

The latter also noticed the movement, raised his head to take a look, and said in surprise: "Chu, Professor Chu?"

"Can I sit here?" Chu Yun asked with a smile and whispered.

Lan Xiaowan was stunned for a moment, nodded again and again, and said, "Of course." "

Chu Yun nodded, put the things in his hand on the table, and didn't intend to continue talking.

After all, in the library, if you keep talking, it will inevitably lead people to look at it, although maybe no one dares to do this to Chu Yun.

But that's rude.

Turning on the computer, Chu Yun started typing a line of words.

[Proof of the two theorems of the Banach space]

This topic was originally something that Chu Yun thought of when he went home last night, and he wanted to write it at night while he had time, but there were some materials that were not borrowed from the library.

How can you not write a dissertation when studying theoretical academics?

And the theorem of the Banach space, for the current Chu Yun, is just a handicap, but in this parallel world, many mathematical theories have not been overcome.

For example, in the original world, relatively complete linear operators, function spaces, etc., have been proved with high probability.

Even the most difficult conjectures have not been proven.

It's not that the level of science and technology and research in this world is not large, but in physics and chemistry, the commercial scale progress brought about by it, and the academic side has not increased much.

As for the proof of the theorem he wrote this time, in Chu Yun's mind, from the process of each step, to the answer, every number, and even the punctuation marks were very clear.

That's what he's been doing for the past two days.

And the only thing that needs to be improved is that the language in Chu Yun's mind is too backbone and beautiful, and he needs to paraphrase it into professional words and enrich the content in him.

It's a transformation from a rational concept into a thesis.

A basic paper that can be understood by many people.

Just as Chu Yun was thinking about how to make a start, a pen beside him reached over and poked Chu Yun's arm.

"Professor Chu, can I ask you a question?"

Lan Xiaowan blushed and asked in a low voice.

Her voice was very thin, and even though she spoke quietly, she still had a pleasant taste, very delicate.

This problem has been difficult for her for a long time, and she wanted to overcome this problem by herself, but she couldn't think of a solution for half a day, so she had to turn to Chu Yun for help.

Chu Yun glanced at her, "Yes, show me the question." "

Lan Xiaowan hurriedly handed over the exercises in her hand, and carefully moved her stool softly.

Chu Yun looked at the question, but it was not very difficult, that is, an abstract question on the linear operator, of course, this question was very difficult for freshmen in the first year.

Judging from Lan Xiaowan's math class, there shouldn't be such a theme as linear operators?

In less than a second, Chu Yun picked up the pen on the table, wrote the final answer directly on the scratch paper, and copied down some key points.

I have to say that Chu Yun's appearance is completely against the sky, and when he is serious about doing things, this attraction and charm are directly magnified hundreds of times.

Lan Xiaowan couldn't help but be fascinated by it.

When Chu Yunyun was exercising, Lan Xiaowan was bored and curiously glanced at the word document screen on Chu Yun's computer.

[Proof of the two theorems of the Banach space]

Abstract:In Banach space theory, the Hahn-Banach functional extension theorem, as one of the three basic theorems of functional analysis, divides the important application relationship of the separation theorem and the Hahn-Banach theorem, and this paper will use the "hyperplane" method to prove the main points of the theorem.

This......

I don't understand!

Banach space Lan Xiaowan is still clear, but what is the functional extension theorem?

What else is called the separation theorem?

Linear operators are good to say, although it is not Lan Xiaowan's learning subject course, but she can also understand the basic calculations of linear operators by studying on her own.

But the Banach space was beyond the scope of what she could basically understand, although Chu Yun wrote it in great detail, she read it like a book from heaven.

A professor of economics working on the proof of a theorem for Banach spaces?

Off topic, off topic!

Do you want to be so perverted?

"Professor Chu, you even specialize in the field of mathematics?"

Lan Xiaowan asked in surprise.

Chu Yun replied simply.

A few days ago, I heard from my classmates that Chu Yun has been looking for books in mathematics and physics, but many people don't know what Chu Yun's skills are in these two aspects.

But under this paper, Lan Xiaowan guessed that Chu Yun would definitely be on the same level as the professor in the field of mathematics.

Of course, empty proof is useless.

"I'm really envious, people who can learn mathematics well are definitely immortals!" Lan Xiaowan sighed, but also had some admiration and admiration for Chu Yun.
