Chapter 324

Chapter 327

there are not a few students who choose to stay in Tsinghua University during the summer vacation.

After all, the summer vacation is not like the winter vacation, with the Spring Festival as a must go home to reunion day, stay in school, can have an excellent learning atmosphere.

The summer vacation is less than two months. Cheng Nuo is as busy as the previous few months. However, it's hard to say that he has a few free days.

The project of inter school cooperation and exchange, and the proof of weak BSD conjecture.

These two things almost occupy 70% of Cheng Nuo's time every day except eating and sleeping. He can only play a few plates of King's and eat chicken and relax.

Everything is going on steadily and steadily.

…………

Summer is burning like fire. In summer, Kyoto is not a place for people.

Cheng Nuo, who was supposed to be at the seaside and blowing the cool sea breeze, walked into the innovation and practice base of Peking University with a bottle of iced drink in one hand and the sweat dripping from his forehead on the other.

In the office specially assigned to Cheng Nuo, all four members of the research group were present.

"Cheng Nuo, you're here. I thought you got heatstroke on the way." Sheng Fei comes forward with a smile.

"Our Kyoto side is pretty good, you go to Jinling there to feel, it will definitely make you doubt that life is constant." Yang Xiao also came to interrupt.

After half a month's running in period, the five became acquainted with each other.

The attitude of several people towards Cheng Nuo is not the contempt at the beginning, but the attitude of equality with themselves, or Higher!

From this period of time Chengnuo that kind of amazing performance, Chengnuo in their mind is a section of the top.

What's more, Cheng Nuo is less than 20 years old now!

Future achievements are unexpected!

Even the guards, who had not dealt with Cheng Nuo before, had to say "be convinced" to Cheng Nuo at this age.

"I heard that sister Yige is in trouble. I'll come and have a look." Chengnuo asked as he passed the towel.

In the past few days, there was no research work of Cheng Nuo in the research plan of the research group. This is not. I heard that the elder sister Yige had some problems in the subject. Cheng Nuo, who had just bought a watermelon in the dormitory to relieve the summer heat, was called to this place urgently.

At this time, the sister Yi Ge came out with some embarrassment and stood in front of Cheng Nuo. She said apologetically, "Cheng Nuo, I'm sorry. It's so hot. Let's come here."

"Sister Igo, it's OK." Cheng Nuo laughed, "it's not far, just a few steps."

"By the way, what can't you solve?" Cheng Nuo asked curiously.

Sheng Fei had no choice but to show his hand. "Our four fields are all biased towards geometry, otherwise we would not be called here."

"And the problem that Yi Ge encountered belongs to the linear calculation of combinatorial mathematics, which we can't help."

"So, call your math all rounder and see if there is any way."

Sheng Fei simply tells Cheng Nuo the story.

Cheng Nuo nodded and said, "what about the specific problem?"

"This way." Sheng Fei leads Cheng Nuo to an office desk.

And that desk, this period of time has been used by Igor.

"Igo, you can simply tell Cheng Nuo." Sheng Fei opens his mouth.

Yige nodded solemnly, leaned down, opened a document on the computer, stroked his hair in his ear, and said, "what I am responsible for studying is the theorem derivation process of integrable symplectic mapping."

"According to Cheng Nuo, we should deduce four equations with respect to Integrable symplectic mappings. The first two theorems are relatively simple and can be deduced only by a few simple steps of logical formula. "

"We can get to the third theorem, that is, to use lax to represent an L (λ) d (λ) = (λ) ∑φ ^ 2. In this process, we must use some knowledge of combinatorial mathematics in order to get a conclusion smoothly."

"Is it here?" Cheng Nuo simply glanced at a line in the document and said.

"Yes, that's it. From formula 2 to formula 3, I don't understand the specific derivation steps. " Igo chicks peck rice like nodding.

Cheng Nuo turns around, pulls a chair, sits on a blank desk next to him, reaches out,

"paper, pen!"

Yige is very attentive for Cheng Nuo handed paper and pen.

"Don't disturb me." After saying this, Cheng Nuo lowers his head and lists the formulas on the paper.

【α=﹤?φ1，φ1﹥（2﹤φ1，φ2﹥-1）﹤?^(-1)φ1，φ1，…… Direct calculation: ∑ D φ 1J ∧ D φ 2J = ∑ NJ 】

five minutes later

PATA!Cheng Nuo closes his pen cap, picks up the A4 size draft paper, which is full of front and back sides, and hands it to Yige behind him.

"This is the derivation step. Take it!"

With that, Cheng Nuo straightened his clothes, waved his hand, and left the office without looking back, leaving everyone a handsome and natural figure.

Downstairs, Cheng Nuo, who walks out of the building in a handsome posture, is dazzled by the heat wave coming from his face.

My sister, I knew that I had been out in the air-conditioned room for a while. This is the most poisonous time of the sun.

There is no way to do it. Facing the high temperature of nearly 40 degrees, Cheng Nuo walks back to the dormitory while wiping sweat.

…………

After the process of Nuo's performance in the office, Cheng Nuo's leading role among the five gradually became apparent.

The progress of the project has been soaring at a speed visible to the naked eye.

On August 23, Cheng opened his second fall semester, which, if nothing unexpected, was his last fall semester at the undergraduate stage.

Because, in less than a year, he will get an undergraduate diploma, as well as a degree certificate in mathematics, bid farewell to the undergraduate career.

The course, of course, is as tense as ever.

However, taking a break from the busy schedule, Cheng Nuo still found the opportunity to take part in the freshmen's orientation work on the first day of school.

Looking at the young faces, full of longing for the University and stepping into the campus, Cheng Nuo couldn't help but shout out:

"Temo Laozi has finally become a senior student!"

After a year's younger brother, Cheng Nuo finally has a chance to call others his younger brother!

At the same time, the benefits of seniors are more than that.

In terms of competition for freshmen, those who have been in school for a year have more advantages than those who have just arrived.

Xuemei, it's ours!

Schoolmaster, it's ours!

Younger brother, it's also ours!!!
