Chapter 364: Goodbye He Youjun

Chapter 364
For the second question, Cheng Nuo glanced briefly and knew what he wanted to investigate.
The same belongs to the field of geometry, which is the Lorentz manifold.
The general situation is the same as that of Riemannian manifolds. It is a difficult field to understand and conquer in geometry.
Lorentz cut the metric space, and Cheng Nuo solved the second problem with times as the base point.
After conquering the BSD conjecture, Cheng Nuo is no longer the former Wu Xia Amon.
A year ago, he thought the problem was as difficult as reaching the sky, but now it seems to be just a little kiss.
Humming joyfully in his heart, Cheng Nuo wrote the formula for solving the second problem.
[A smooth quantitative manifold M is called the tangential space. If there is an overall 1-forming η and a whole body smooth vector field ζ and a 1-1 row tensor φ satisfying: η(ζ)=-1, φ^2X=X+η(X)ζ.】
[If a Lorentz metric g is given on M, so that g:TpMTpM→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 dense, it is a series of formulas.
If patients with intensive phobias are here, I am afraid the brains that have already been seen hurt.
Cheng Nuo didn't care, lowered his head, perfecting his thinking step by step.
It took the same time as the first question. After twenty minutes, Cheng Nuo finished the work.
Coupled with the time for reading questions and thinking about ideas, up to now, the test time has only passed less than an hour.
To be precise, fifty-four minutes.
This time can be said to be quite long!
Cheng Nuo looked around the classroom and found that most of the people were answering questions with their heads down. Of course, there were also one or two empty eyes looking ahead, deeply suspicious of life.
What's so...How can this question be so difficult!
Then, condemning them for the difficulty of this topic, they suddenly saw a figure standing up from the seat.
Isn't this the undergraduate kid?
Did he...
No way? !
Cheng Nuo deliberately walked lightly, but the other eleven candidates noticed Cheng Nuo's side.
So, in shock, or amazement, and a little confused gaze, Cheng Nuo walked up to the examiner's position in front and said to the potbellied man who was bowing his head, "Examiner, I'm finished. ."
The pot-bellied man raised his head and stared at Shang Cheng Nuo's sincere little gaze. After a full four or five seconds, he gradually reacted, "Okay, give it to me."
The potbellied man took the test paper and put it in a sealed bag.
Cheng Nuo, who completed the task, walked out of the testing classroom without incident.
The results of the test will only come out the day after tomorrow, but based on the current situation alone, Cheng Nuo is already pretty sure.
Sure enough, two days later, the Ministry of Education issued a notice to Cheng Nuo.
It is said that Cheng Nuo stood out from the twelve people by virtue of his excellent performance in the test, and got the opportunity to go to the Massachusetts Institute of Technology in the United States as an assistant to Professor Fresnel, a Fields Medalist.
Originally, if Cheng Nuo hadn't suddenly joined midway, the students competing for this opportunity would be doctoral students.
Then there is no need to continue studying abroad for Ph.D.
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 the assistant position, but also get the opportunity to study for a doctorate at MIT.
The tuition fee is borne by the state.
The Massachusetts Institute of Technology starts in September and will arrive in the United States in August.
There is not much time left for Cheng Nuo.
…………
This summer, Cheng Nuo did not stay in school to study topics like last year.
He hurried back to Qingcheng to spend this wonderful summer with his parents and Mu Leng.
During this period, Cheng Nuo wanted to take advantage of this long-distance relationship to separate from the sorrow, and get Mu Leng's blood.
But Mu Cooling didn't buy it, saying that he would wait until Cheng Nuo returned from his studies.
Cheng Nuo instantly felt pain.
To get a doctorate from MIT, four or five years of study is at least.
By that time, I am afraid that my unicorn arm magic has been accomplished!
No, Cheng Nuo will never allow this to happen!
Isn’t it a PhD? Let me get it done in two years!
In terms of hard power, Cheng Nuo is definitely higher than 99.9% of doctoral students. This is true even in top universities like MIT and Princeton.
With a secret plan in mind, Cheng Nuo recharged at home, reading books and articles related to geometry.
…………
In August, Qingcheng was still a hot summer.
Even in coastal cities, the outdoor temperature is still hot, making life doubtful.
Countless citizens were in the air-conditioned room, thanking Comrade Tesla.
Changting Airport, Qingcheng on a flight to the United States.
Cheng Nuo sat in a position by the window, looking at the shrinking Qingcheng in his sight, and sighed.
"Goodbye, Qingcheng!"
…………
Massachusetts Institute of Technology is located in Cambridge, Massachusetts, in the metropolitan area of ​​Boston, Massachusetts.
After twelve hours of rushing, the plane landed slowly at 7 am New York time.
Pulling the suitcase, Cheng Nuo walked out of the airport.
Although this is not the first time to come to the United States, Cheng Nuo is still unfamiliar with this country.
The first time I came here just to participate in the game, and 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, a young man in casual clothes leaning against a Maserati car looked around the crowd coming out of the battle.
Suddenly, his eyes fell on Cheng Nuo, who was pulling the suitcase.
He waved his hand and shouted in Chinese, "Cheng Nuo, here, here!"
"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 no one else. It is because of classmate He Youjun who has a deep relationship with Cheng Nuo in the fifth season of "The Strongest Brain".
As mentioned before, he is a graduate student in economics from MIT. It is not surprising to appear here.
Before coming to America, Cheng Nuo, who was unaccompanied, thought of He Youjun, a friend who also studied at MIT.
Although they haven't seen each other for two years, they often keep in touch in private.
After all, they all belong to the talented players of this era, they have many common topics, and there is no pressure to talk.
"Come on, get in the car!"
He Youjun shook his middle-handed bag, and finally opened the car door with a toothpick in his mouth.
On the road, the car speeds on the road.
Cheng Nuo also put his head out of the car, admiring this exotic customs~EbookFREE.me~ Have you found a good place to live? He Youjun spit out the toothpick in his mouth and asked.
Cheng Nuo shook his head, "No, let's live in the school dormitory first."
He Youjun shrugged, "That would be inconvenient, or else, do you live with me?"
"What about you?" Cheng Nuo said 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's really a bit empty and lonely."
emptiness? lonely? ! !
Cheng Nuo tightened.
