Chapter 361 Goodbye He Youjun

364 chapter

Cheng Nuo took a quick glance at the second question and knew what he was going to investigate.

The same belongs to the field of geometry and is the Lorentz manifold.

It is the same as the general situation of the Riemannian manifold, which is a difficult field to understand and conquer in geometry.

Lorenz cut off the metric space, and Cheng Nuo used this as the base point to solve the second problem.

After the training of overcoming the BSD conjecture, Cheng Nuo is no longer the former Wuxia Amon.

A year ago, he thought that the topic was as difficult as heaven, but now it is just a small kiss.

Humming happily in his heart, Cheng Nuo wrote down the solution formula for the second question.

【一个光滑定量流形M称为切触空间，如果其上具有一个整体的1-形成η和一个通体光滑矢量场ζ和一个1-1行张量φ满足：η(ζ)=-1，φ^2X=X+η(X)ζ.】

[If a Lorentz metric g is given on M, so that g: TpM*Tp*M→R is a signed non-degenerate inner product, and satisfies g(φx, φy)=g(X, Y) +η(X)η(Y), g(X, ζ)=η(X). Then it is called...]

…………

Densely packed, another series of formulas.

If a patient with intensive phobia was here, I am afraid that his head would hurt from seeing it.

Cheng Nuo didn't care. He lowered his head and perfected his thinking step by step.

It took the same time as the first question. After 10 minutes, Cheng Nuo finished it and called it a day.

Coupled with the time for reading the questions and thinking about ideas, up to now, the test time has only passed less than an hour.

54 minutes, to be exact.

This time can be said to be quite long!

Cheng Nuo looked around the classroom and found that most of the people were lowering their heads to answer the questions. Of course, there were also one or two staring blankly ahead, deeply suspicious of life.

Damn...why is this question so difficult!
Then, they who condemned the difficulty of this question suddenly caught a glimpse of a figure standing up from their seats.

Isn't this the undergraduate kid?
Did he...

No way? !

Cheng Nuo deliberately walked lightly, but the other eleven candidates all paid attention to Cheng Nuo's side.

So, under their shocked, horrified, and confused gazes, Cheng Nuo walked up to the examiner in front of him, and said to the potbellied man who was reading the novel with his head down, "Examiner, I Done."

The potbellied man raised his head and met Cheng Nuo's sincere gaze. After being stunned for four or five seconds, he gradually realized, "Okay, give it to me."

The pot-bellied man took the test paper and placed it in a sealed bag.

After completing the task, Cheng Nuo walked out of the testing classroom without incident.

The results of the test will not come out until the day after tomorrow, but based on the current situation alone, Cheng Nuo is already sure.

Sure enough, two days later, the Ministry of Education sent Cheng Nuo a notice.

It is said that Cheng Nuo stood out from the 12 students by virtue of his excellent performance in the test, and won the opportunity to go to the Massachusetts Institute of Technology in the United States as an assistant to Professor Fresnel, the leader of the Fields Medal.

Originally, if Cheng Nuo hadn't suddenly joined midway, the students competing for this opportunity would all be doctoral students.

Then there is no such thing as continuing to study for a PhD abroad.

However, Cheng Nuo's success in the competition caught the Ministry of Education by surprise.

Therefore, as a fringe benefit, Cheng Nuo will not only get an assistant position, but also the opportunity to study for a Ph.D. at the Massachusetts Institute of Technology.

For public-sponsored study abroad, the tuition fee is borne by the state.

The Massachusetts Institute of Technology starts school in September, but Nuo will arrive in the United States in August.

There was not much time left for Cheng Nuo.

…………

This summer, Cheng Nuo didn't stay in school to research the subject like he did last year.

He rushed back to Qingcheng to spend this wonderful summer vacation with his parents and Mu Leng.

During this period, Cheng Nuo wanted to take advantage of this long-distance relationship to separate Yu Lichou and get Mu Leng's first blood.

But Mu Liangliang didn't buy it at all, saying that he would wait until Cheng Nuo returned from his studies.

Cheng Nuo's egg hurts instantly.

If you want to get a doctorate from MIT, you need to study for four or five years at least.

By that time, I am afraid that my unicorn arm magic has already been completed!
No, Cheng Nuo will never allow this to happen!
Isn't that just a doctorate?Watch me get it done in two years!

In terms of hard power, Cheng Nuo is definitely higher than 99.9% of the doctoral students.This is true even in top universities like MIT and Princeton.

With a secret plan in mind, Cheng Nuo recuperated at home and read books and articles related to geometry.

…………

In August, Qingcheng is still a scorching summer.

Even in coastal cities, the outdoor temperature is still so hot that people doubt life.

Countless citizens stayed in air-conditioned rooms, thanking Comrade Tesla.

Changting Airport, on the flight from Qingcheng to the United States.

Cheng Nuo sat by the window, looked at Qingcheng, which was getting smaller and smaller in sight, and sighed.

"Goodbye, Qingcheng!"

…………

MIT is located in Cambridge, Boston, Massachusetts, USA.

After twelve hours of running around, the plane landed slowly at [-]:[-] am New York time.

Pulling the suitcase, Cheng Nuo walked out of the airport.

Although this was not the first time he had come to the United States, Cheng Nuo was still unfamiliar with this country.

The first time I came here was just to participate in the competition, and I was accompanied by coach Hong Zhong, but this time, Cheng Nuo came to a foreign country alone.

Fortunately, Cheng Nuo barely had an acquaintance in Boston.

At the airport pick-up, a young man in casual clothes, leaning against a Maserati, looked around the crowd walking out of the exit.

Suddenly, his eyes fell on Cheng Nuo who was pulling the suitcase.

He waved his hand and shouted loudly in Chinese, "Cheng Nuo, this way, this way!"

"Brother Youjun, thank you for coming to pick me up!!" Cheng Nuo smiled and walked over and hugged the young man.

This young man is none other than He Youjun, who formed a deep bond with Cheng Nuo in the fifth season of "The Most Powerful Brain".

As mentioned before, he is a combined master and doctoral student in economics at the Massachusetts Institute of Technology.It's not surprising to be here.

Before coming to the United States, the unaccompanied Cheng Nuo thought of He Youjun, a friend who also studied at MIT.

Although they haven't seen each other for two years, the two often keep in touch in private.

After all, they are all talented players of this era, and they have many topics in common, and there is no pressure in the conversation.

"Come on, get in the car!"

He Youjun flicked his coquettish mid-part hairstyle, and finally opened the car door with a toothpick in his mouth.

On the road, the car is speeding on the road.

Cheng Nuo also poked his head out of the car, admiring the customs of this exotic land.

"Have you found a place to live?" He Youjun spit out the toothpick in his mouth and asked.

Cheng Nuo shook his head, "Not yet, let's live in the school dormitory first."

He Youjun shrugged, "That's so inconvenient, how about you stay at my place?"

"What about you?" Cheng Nuo lightly snorted.

He Youjun nodded, and met Cheng Nuo's eyes, "Yes, just stay at my place. It's such a big place, and I'm the only one living there. It's really a bit empty and lonely."

emptiness?lonely? ! !
Cheng Nuo's chrysanthemum tightened.
