Chapter 412

quitting the research gate, Cheng Nuo, who is bored, is in a daze with his chin.

Picking up the mobile phone on the desk, Cheng Nuo is just about to go out for a stroll when he sees a phone call coming up from the mobile phone.

The caller on the mobile phone is "Chali".

Cheng Nuo didn't respond at first. After a few seconds, he remembered that it was his little white fan.

"It's me, Cheng Nuo." Cheng Nuo answers the phone.

"Great God, great God, I am zari." Although zari had tried his best to suppress his excitement, his voice was still a little shaky.

Cheng Nuo frowned slightly, "I know. Can I help you? "

"Where are you now, God?" Chali rubbed his hands and asked tentatively.

Cheng Nuo eyebrows a pick, "I am in the school's experimental building this side, just want to go out for a walk."

"Do you have time now Chali asked uneasily.

"Time..." Cheng Nuo tilted his head and thought, "my next job will start tomorrow. There is nothing else today. Do you want to ask me about this

"Indeed, if I can, I'd like to ask God for a favor..."

…………

Ten minutes later, Cheng arrived at building 3, opposite the student center at the University of science.

"203, this is what zari said."

On the second floor, Cheng Nuo stands in front of gate 203 and knocks.

The door was soon pushed open, revealing the familiar face of Chali's classmate. He first showed a surprised look, and then politely called Cheng Nuo in, "God, you are here. Please come in, please come in!"

Cheng Nuo nods and steps into the room.

In addition to one of his classmates, there were also three women in his room.

A look of amazement flashed over his three faces as he led a man who looked younger than them.

A boy stood up and asked with a bitter smile, "Chali, is this the God in your mouth? He's not as old as you are, isn't he? "

"Milo, that's not what I said. Although the great God is still in graduate school one, age does not mean everything. "

"What, what do you say?" The boy grasped another key point in zari's words. He pointed to Cheng Nuo in an inexplicable tone, "you said he was still in graduate school one."

"Yes, God is the freshman in our science school this year." Chali classmate answered naturally.

Freshmen

The boy's mouth twitched.

Third year graduate students, they are third grade graduate students!

Even if it's not as good as it is, it's not enough for Chari to invite a freshman to guide them!

"Charlie, come here first." The boy pulled zari to one corner, frowned, and asked in a low voice, "zari, are you confused? What we have encountered is not an ordinary problem. We can't solve all four of us. Do you think a person who is two years younger than us will have a solution?"

It is good that they are in trouble now, but he does not think that the "great God" invited by zari can solve the problem.

After being reprimanded by the boy, zari looked very wronged. "Milo, I didn't say that just now. The ability of the great God is not related to his age."

"Although I was quite shocked when I realized the reality at that time. But the fact is the fact, he's there, and we have to be, there are people in the world who are many times more talented than we are. "

The boy's brow frowns deeper, "but that kind of person also a few times." He glanced at Cheng Nuo not far away, "but I don't think he is such a person."

The students in Chali took a puff from the corner of their mouth.

This classmate of oneself, must let him be hit hard in the face, only then can recognize the fact!

"Yes or no, just give it a try." Chali said, "since the gods are here, we can't just drive him back?"

Seeing Milo's face ready to move, Chali said, "if you really dare to do this, I'll go after you in the next second!"

The boy finally compromised and said, "let him have a try. Well, if the teacher isn't here, we can't do this."

The project will be handed over next month, but unfortunately, their tutor is going on a business trip at this time. Therefore, they can only stare at the most important stage when they encounter problems that cannot be solved.

That is to say, tsari thought of the idea of moving and rescuing soldiers. He thought that he would call their senior student of thigh level. But I didn't expect that the visitor was a freshman who was two years younger than him.

Milo instantly felt that the future of their project was dim.

Chali that side, has been back in front of Cheng Nuo, "God, let you wait for a long time."Cheng Nuo shook his head and said with a bitter smile, "I'm used to it. When I go out next time, I want to stick a beard on my chin."

"Well, take me to see the trouble you're in. I'll be home early for dinner." Cheng Nuo raised his wrist and took a look at the time and said faintly.

"Oh, good." Chali led Cheng Nuo to his desk, took out a pile of thick A4 paper and handed it to Cheng Nuo, "this is all the progress of our research project. God, you should know something about it first, and then I will talk about the specific problems

Cheng Zha handed over a pile of paper.

The title of the project that the four member team is studying is called "boundary value problems of Nonlinear Differential Equations with fractional derivatives". In terms of the difficulty level, it belongs to the normal level of research projects of MIT postgraduates.

As for the subject of geometric homology to be done by Cheng Nuo, there is no natural way to compare it.

After all, one is a joint project of several professors, and the other is just a project for graduate students to practice. As for the practical application significance of the research results, it can be almost ignored.

Don't say it's Cheng Nuo now. Even if he was a year ago, he would not have any interest in such a level of subject. Cheng Nuo would not be bored to such a state if his loyal fan brother did not ask him to come here.

This subject is to study the boundary value problems of Nonlinear Differential Equations with fractional derivatives by using continuous functions.

The continuous function is constructed by using the infimum theorem and monotone boundedness theorem, combined with the construction method. Under the condition of given fractional derivative, the perturbation method is introduced. The integral operator of nonlinear fractional derivative is defined by Green function, and the nonlinear differential equation edge of fractional derivative in continuous function space is proved by using Banach contraction mapping theory Value has a unique solution.

Cheng Nuo simply scanned the content of A4 paper to understand the specific research framework of this topic.

Now, they are stuck in the final proof of the existence and uniqueness of the boundary value of the nonlinear differential equation with fractional derivative in the continuous function space.
