Ultimate Scholar

Chapter 9 Just a few seconds... cough cough

It's fine if you can study physics, but it's admirable to be able to learn physics so deeply.

And at the same time, it is possible to study physics and mathematics textbooks in foreign languages, so it can only be praised by big guys.

Suddenly, she came back to her senses, wait, variational inequality?

This mathematical method is also used in economics and finance, and she, who studies finance, is currently learning the content of variational inequalities, and even encountered learning problems.

She opened her mouth, and finally whispered: "Student, classmate?"

Seeing that Li Mu didn't respond, she sighed and had no choice but to reach out and pat Li Mu's shoulder.

Li Mu's hand that was typing stopped, and suddenly he came back to his senses, and turned his head to look at the person who patted him.

With his current memory, he recognized this girl almost immediately.

Then he realized that he had forgotten the time again.

"Ah... sorry, I'm leaving now."

A skillful ctrl+s, alt+f4 closed the interface, and then directly closed the computer.

"No, no, classmate, I just want to ask you, do you know variational inequalities?"

Yun Rongshang hurriedly asked.

"Variational inequality? Oh, I will."

Li Mu nodded, of course he would, although the variational inequality is also a big knowledge point, but he knows quite a lot.

Otherwise, I would not have written a paper related to this.

"Then can I ask you a question?"

After speaking, Yun Rongshang took out a small notepad from his pocket, flipped through it, and finally turned to a page, then handed it to Li Mu.

"I've been thinking about this question for a long time today, but I can't write it."

Came to ask a question?

Li Mu was stunned for a moment, then nodded, and took the small notepad.

"Let me be healthy."

The small notepad is very small, but the girl's handwriting is also very beautiful and small, just enough to write an inscription in it.

This is a problem in the economic field, and more simply, it is a problem of optimization.

Variational inequality is a mathematical method used to find the optimal solution or equilibrium state in the economic field.

And this problem is mainly to solve the variational inequalities.

After thinking for a while, Li Mu took a draft paper from the side and started writing.

"This problem is indeed relatively difficult in variational inequalities. The most critical point is how to combine these variational inequalities."

After speaking, Li Mu began to write.

"By treating each variational inequality in the problem of simultaneous variational inequalities as a variational inequality problem with parameters, under the assumption that each variational function is strictly monotonic, each variational inequality with parameters can be Determine an implicit function with parameters as independent variables about its solution, and prove the continuity of the implicit function under appropriate conditions..."

"And then using Brouwer's fixed point theorem..."

Following Li Mu's narration, the draft paper was also filled with the solutions he gave.

"OK, it's done. This question is not bad, but it's strange why the question is related to the economy."

"You majored in economics?"

Li Mu said casually, while turning his head to look at the girl next to him.

However, Yun Rongshang was already dumbfounded.

Who is she and where is she?

Why do you feel like you are listening to a bible?

is she in heaven

"Student? Classmate?"

Li Mu shouted again, feeling a little strange in his heart.

This girl looks quite handsome, why is she a little dumbfounded?

And Yun Rongshang finally came back to his senses at this time, and asked weakly: "Classmate... oh no, senior, can you say it again? I... didn't understand."

At this time, Li Mu has become a senior in his eyes, and he may be at the level of a doctor.

"Well……"

Li Mu was stunned for a moment, senior?

He is only a freshman, is there still a big zero in our school?

Forget it, let's not worry about it, and then he explained it carefully to Yun Rongshang again. \b

For him, giving lectures to others is also a review of relevant knowledge points, so he is quite happy to do this kind of thing.

In this way, he spent five or six minutes re-telling Yun Rongshang.

And Yun Rongshang has gradually changed from half-understanding to mastering the seven or eighty-eight, and she needs to comprehend the remaining knowledge points by herself.

"Thank you so much! I wasted your time."

Holding her small notebook, Yun Rongshang looked at the problem-solving steps and ideas written on it, and said gratefully.

Li Mu smiled and waved his hands: "You're welcome, the question is actually quite simple, and it didn't delay me much, it only took a few seconds... Cough cough, what I mean is, for you who study financial economics, this kind of question is indeed still a problem. It's a little more difficult."

Delayed for a few seconds...

Ah... are you pretending I didn't hear you?

Yun Rongshang wanted to roll her eyes, but when she thought that she just got her own question, she started to talk about it...

People seem to be telling the truth.

But at this moment, a voice suddenly came: "Xiaoyun, you are here, I see you haven't come back for a long time, I thought something happened."

The two turned their heads and saw their library aunt coming over.

Yun Rongshang's face flushed, she forgot about her job when she was asking for advice here.

"Ah, I'm sorry, Auntie, I'm here to ask this classmate a question, clean up now!"

The aunt waved her hand and said, "Forget it, it's so late, you students study hard, you'd better go back and rest early, I'll clean it up."

"That's it... well, then thank you, Auntie." Yun Rongshang noticed that it was almost eleven o'clock, and said gratefully.

Li Mu also noticed the time, so he quickly packed up his things. He had to get up at six in the morning. Although his sleep quality was good, he still had to sleep for six hours a day.

Just like that, he took his schoolbag and left the library quickly without talking to the girl, but just after walking a few steps, he heard "Hello" from behind.

Turning around to look, it was the girl just now, who was following up with her schoolbag on her back.

"Thank you for teaching me just now." Yun Rongshang said, "My name is Yun Rongshang."

"It's okay, didn't you thank you all." Li Mu waved his hand to show that he didn't care, "My name is Li Mu."

Yun Rongshang smiled lightly, and then asked curiously: "Actually, I want to ask, are you really from the Department of Physics?"

"That's not it." Li Mu spread his hands.

"It feels more like you are from the mathematics department."

Li Mu touched his nose.

Department of Mathematics?

Maybe, he might be more suitable for the Department of Mathematics now. Computers and mathematics in his mind are simply a natural match.

Physics has become a junior.

But he still has a place in his heart for physics, after all, this is his first love.

"By the way, were you writing a thesis just now? SCI?"

"Yeah, you can actually see it?" Li Mu couldn't help but take another look at the girl.

Yun Rongshang said: "I don't understand, and the books you read are so advanced, then it must be SCI."

Li Mu: "..."

Seems to make sense.

But he felt that if he just picked up a textbook on electromagnetism, it would be very advanced for this girl, right?

She doesn't understand science.

At this time, they also came to a crossroads, Yun Rongshang pointed to a building at the end of a road, "Senior, your dormitory is over there."

"ah?"

Li Mu was stunned for a moment, and then glanced at the building that Yun Rongshang pointed to, which was the dormitory for graduate students.

He shook his head, then pointed to another intersection, which was the undergraduate male dormitory.

"I'm not a senior, unless you are a big zero, I'm going this way, goodbye."

As he said that, he walked towards the other side.

Yun Rongshang was left in a daze.

What?

Not a senior, unless she is Big Zero?

Does it mean that this person is only a freshman?

junior?

you?
