Chapter 364

On the second question, Cheng Nuo simply glanced at it and knew what he wanted to investigate.

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

As is the case with Riemannian manifolds in general, they are one of the more difficult areas of geometry to understand and overcome.

Lorentz excised the metric space, and Cheng Nuo used the second problem as the base point.

After overcoming the BSD conjecture, Cheng Nuo is no longer the Wuxia Ameng he once was.

A year ago, he thought it was a difficult topic, but now it seems like a small kiss.

Humming a song in his heart, Cheng Nuo wrote down the formula for solving the second problem.

[A smooth quantitative manifold M is called a tangential touch space, if there is an overall 1-forming η and a whole smooth vector field ζ and a 1-1 line tensor on it φ satisfies the following: η(ζ)=-1,φ^2X=X+η(X)ζ.]

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

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

It's dense, and it's a series of formulas.

If the person with dense phobia is here, I am afraid that the brain will hurt for a long time.

Cheng Nuo didn't care, lowered his head, and improved his thinking step by step.

It took the same time as the first question, and after 20 minutes, Cheng Nuo finished the work.

Coupled with the time to read the questions and think about ideas, the test time has only passed for less than an hour so far.

Fifty-four minutes, to be exact.

That's a long time!

Cheng Nuo looked around the classroom and found that most of the people were bowing their heads to answer the questions, of course, there were also one or two who looked ahead with empty eyes, deeply doubting their lives.

Amazing...... Why is this question so difficult!

Then, condemning the difficulty of the question, their eyes suddenly caught a glimpse of a figure rising from their seats.

Isn't that the undergraduate kid?

Could he ......

No way?!

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

So, under their shocked, shocked, and a little confused gaze, Cheng Nuo stepped into the position of the examiner in front of him and said to the pot-bellied man who was bowing his head, "Examiner, I'm done." ”

The pot-bellied man raised his head and looked at Cheng Nuo's sincere little gaze, and was stunned for four or five seconds before he gradually reacted, "Okay, give it to me." ”

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

Cheng Nuo, who completed the task, walked out of the test 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 nine out of ten.

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

It is said that Cheng Nuo, with his excellent performance in the test, stood out from 12 people and won the opportunity to go to the Massachusetts Institute of Technology to serve as the assistant to Professor Fresnel, the Fields Medal boss.

Originally, if Cheng Nuo hadn't suddenly joined halfway, the students competing for this opportunity would have been 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 off guard.

Therefore, as a fringe benefit, Cheng Nuo will not only get an assistant position, but also the opportunity to study for a doctorate at MIT.

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

The Massachusetts Institute of Technology will start school in September, but it will be rushed to the United States in August.

There is not much time left for Cheng Nuo.

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

This summer, Cheng Nuo did not stay in school to research topics like last year.

He rushed back to Qingcheng and spent this wonderful summer time with his parents and Mu Leng.

During this period, Cheng Nuo wanted to take advantage of the separation of this long-distance relationship and get Mu Leng's blood.

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

Cheng Nuo's egg hurt instantly.

If you want to get a Ph.D. from MIT, you need to study for four or five years.

At that time, I'm afraid that my unicorn arm magic skills have been completed!

No, Cheng Nuo will never allow this kind of thing to happen!

Isn't it a Ph.D.? Watch me do it in two years!

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

Secretly making a plan in his heart, Cheng Nuo recuperated at home and read books and articles related to geometry.

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

In August, Qingcheng is still a hot summer.

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

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

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

Cheng Nuo sat in a window position, looking at Qingcheng that was shrinking in his line of sight, and sighed.

"Goodbye, Qingcheng!"

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

The Massachusetts Institute of Technology is located in Cambridge, Boston, Massachusetts.

After twelve hours of travel, at 7 a.m. New York time, the plane slowly landed.

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

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

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

Fortunately, in Boston City, Cheng Nuo barely has an acquaintance.

At the pick-up point, a young man dressed in casual clothes leaning on a Maserati car looked at the crowd that walked out of the battle entrance.

Suddenly, his gaze 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 Jun, thank you for coming to pick me up!!" Cheng Nuo walked over with a smile and hugged the young man.

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

As mentioned earlier, he is a master's and doctoral student in economics at the Massachusetts Institute of Technology. It's not surprising that it's here.

Before coming to the United States, Cheng Nuo, who had no relatives, thought of He Youjun, a friend who also studied at MIT.

Although they hadn't seen each other for two years, the two often kept in touch privately.

After all, they all belong to the geniuses of this era, and there are many common topics, and there is no pressure to talk at all.

"Come on, get in the car!"

He Youjun shook off the middle of his bag, and finally opened the car door with a toothpick in his mouth.

On the road, cars are speeding down the road.

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

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

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

He Youjun shrugged, "How inconvenient is that, why don't you live with me?"

"What about you?" Cheng Nuo sighed lightly.

He Youjun nodded and looked at Cheng Nuo's gaze, "Yes, just live with me, in such a big place, I live alone, it is indeed a bit empty and lonely." ”

Emptiness?loneliness?!!

Cheng Nuo's chrysanthemum tightened.
