Chapter 304

The next day, Cheng Nuo reluctantly received the special scholarship of 15,000 yuan and the award certificate. Under the envious gazes of the three roommates, they casually left the certificate on the desk.

He gently shook the envelope in his hand, "I'll have a treat tonight, you can choose the location!"

The three of them shouted in unison: "Long live Cheng Nuo!!"

Another half month passed.

The Organizing Committee of the National College Student Competition announced the list of winners of this year's competition.

A total of seven students from Tsinghua University participated in the finals of the first and second year groups, and won five first prizes and two second prizes.

And Cheng Nuo naturally won the first prize indisputably.

And, according to the news from the organizing committee, Cheng Nuo is the only player who has won a full score in the finals of the mathematics competition in the past five years, of course, the range of this full score also includes the last two additional questions.

Xu Jie, a student from Peking University, also won the first prize in the competition.

It's just that when he saw the name of Cheng Nuo, who was first on the list of first prize winners, he was not in a good mood.

The other students were exhausted and fought for three hours before they could barely win an award. But Cheng Nuo was good, and it only took him an hour to easily get a grand prize back. It's really like what Cheng Nuo said before, if it weren't for the fact that there was no grand prize in the number competition, then there might be no suspense about this place this year.

Sure enough, even if they are top students, they are divided into different levels.

............

"Professor Lu, are you looking for me?"

The day after the Organizing Committee of the National Collegiate Mathematics Competition announced the list of winners, Cheng Nuo was called to the office by Professor Lu.

Professor Lu's attitude towards Cheng Nuo has turned 180 degrees compared to half a year ago, and he patted the sofa, "Come, sit down first." ”

"This is your award certificate, put it away first. Professor Lu handed the award certificate with the red cover and gold stamping on the desk to Cheng Nuo.

This is already the first certificate that Cheng Nuo doesn't know how many certificates he has taken, and his mood has become numb, so he just took it with a polite smile.

"Teacher, you brought me here today, don't you just give me this certificate?" Cheng Nuo said with a smile.

Professor Lu crossed his fingers, "Indeed, I called you this time, there is indeed something to ask for your opinion." ”

"You've done a math project before, right?" asked Professor Lu.

Cheng Nuo nodded, "Well, last semester, I followed Professor Liao and a few seniors to do a project on the two-dimensional Helmholtz equation. ”

Professor Lu leaned back in his chair, "I know about this project, and I heard that it has been done well. ”

He pondered for a moment and continued, "I told you before that Professor Liu from Peking University gave me a project, right? This project is a research project jointly discussed by the National Natural Science Foundation of China and researchers from our two universities a few months ago. Now we have taken it. ”

The name of the project has not yet been decided, but the direction of the research has already been decided. This paper mainly studies the problems of the monotonicity of the p-Laplacian operator and the zero-point iteration of the extremely monotonic operator. ”

The p-Laplacian operator is a second-order differential operator in an n-dimensional Euclidean space, defined as the divergence div of the gradient grad. This law can be calculated using an operation template.

The maximal monotonic operator refers to the monotonic and undiminished derivative function of the differentiable convex function on a straight line, and the operator satisfies T:X→X'.

Cheng Nuo interjected, "This should be regarded as a research topic in applied mathematics, right?"

Moreover, they are all hot topics in the field of applied mathematics today.

Cheng Nuo usually reads some math magazines. Whether it is the p-Laplacian operator or the zero-point problem of the extremely monotonic operator, it is a popular fried chicken in the field of mathematics today.

Less than four months have passed in 2020, but there have been dozens of research papers on these two research directions from major universities.

Professor Lu smiled and did not deny Cheng Nuo's words, "That's right, this is indeed the research direction of the branch of applied mathematics, how about it, are you interested?"

Listening to Professor Lu's words, it seems that ......

Cheng Nuo said uncertainly, "Teacher, you want me to ......"

"Yes, I want you to join the research group of this project. Professor Lu explained the real purpose of calling Cheng Nuo.

"But teacher, the subjects I am studying now are all basic mathematics, and I don't know much about the subjects in the field of applied mathematics. Cheng Nuo is telling the truth.

Applied mathematics does not focus on theoretical research like basic mathematics, but focuses on practical applications.

But like the high algebra and numeracy that Cheng Nuo is learning now, they are all pure mathematical things. Courses in the field of applied mathematics have not been covered at all.

Professor Lu waved his hand and smiled, "I don't know much, you can learn it!" Anyway, the estimated research time for this topic is half a year, with your learning talent, is there anything you can't learn in half a year?"

That sounds right!

Cheng Nuo is still quite confident in himself.

In this case, Cheng Nuo has no reason to let go of the research opportunities that were sent to him in a hurry, you must know that ordinary students who want to do project projects have to queue up slowly.

Cheng Nuo nodded, full of pride, "Okay, teacher, I took this project!"

"I promise that the research of this project will be completed perfectly. ”

Professor Lu patted Cheng Nuo on the shoulder and smiled, "Don't say this to me, although I applied to win this project, the instructor of this project is not me." ”

"My main focus is functional analysis, which is not compatible with applied mathematics. Therefore, the institute decided to hand over this topic to Professor Niu Fang, a professor in the field of mathematics, as an instructor. ”

Professor Lu handed Cheng Nuo a note, "This is Professor Fang's phone number and address. I've already said hello to him, so I'll just report for duty tomorrow. ”

"Okay, thank you, teacher. Cheng Nuo put the note in his pocket.

Cheng Nuo got up, "Then teacher, if there is nothing else, then I will leave first?"

Professor Lu nodded, "Well, there's nothing else, you can go first." ”

As soon as he left Professor Lu's office, Cheng Nuo hadn't taken two steps when he met Professor Liao coming up from downstairs.

"Hello Professor. Cheng Nuo said hello.

As soon as Professor Liao looked up, he also saw Cheng Nuo, with a hint of joy on his face, "It's you, Cheng Nuo." ”

"It just so happens that I have something to look for you, let's go, come to my office. Without allowing Cheng Nuo to refute, Professor Liao pulled Cheng Nuo into the office on the same floor as Professor Lu.

"Professor, what are you looking for me?" asked Cheng Nuo.

Professor Liao smiled, "It's a good thing! Don't worry, you sit down first, we'll wait for someone." ”

Cheng Nuo sat on the sofa with a wry smile, "Okay." ”

Knock knock~~!

About ten minutes later, there was a knock on the door.

"Please come in. ”

Push the door and people come in. And the person who came in was none other than Cheng Nuo, a junior in the mathematics department, Wang Genji.
