Cheng Hao left Nassau Hall with his student card and his freshman admission handbook and dormitory key.
After leaving the door, senior brother Wang Yiming was still waiting for him there.
"Brother!"
"How's it going? Is it done?"
Wang Yiming asked Cheng Hao with a smile.
"It's done!"
Cheng Hao nodded.
"By the way, I haven't asked yet, which supervisor did you work with for your Ph.D.?"
Wang Yiming suddenly thought of something at this time, and he asked Cheng Hao in front of him curiously.
Cheng Hao smiled and said helplessly.
"I still have to go to the interview myself, but Professor Witten has offered me an olive branch before, and I'm still considering it."
"Professor Witten!"
Hearing Cheng Hao's words, Wang Yiming was suddenly shocked. He looked at Cheng Hao in front of him with a curious look in his eyes and asked: "That's the winner of the Fields Medal! And he is in the field of physics."
They are also the top few! Why don’t you agree?”
Looking at Wang Yiming's curious eyes, Cheng Hao shrugged.
"I particularly admire his achievements, especially his use of Jones polynomials to explain the Chern-Simens theory. I particularly like his research. I think this is one of his best results in the field of pure mathematics.
,This research has a profound impact on low-dimensional topological ,structures and deduces quantum invariants.
I personally think that this should be his highest achievement in mathematics, but I..."
Before Cheng Hao could finish his words, he was overheard by a passing student.
"Professor Witten's greatest contribution should be his research on topological quantum field theory. This research is truly exciting!"
A white student with messy hair pushed up his glasses, looked at Cheng Hao and said seriously.
The white boy looked at Cheng Hao in front of him calmly.
Hearing the boy's words, Cheng Hao was stunned for a moment and looked at Wang Yiming beside him. At this time, Wang Yiming also looked at Cheng Hao in front of him.
The two looked at each other.
"Junior, there are still a lot of crazy people doing scientific research in this school, let's go!"
Wang Yiming smiled bitterly and said to Cheng Hao in front of him.
"There's no rush."
Cheng Hao pondered for a moment, then looked at the white boy in front of him and said: "I'm talking about Professor Witten's research in the field of pure mathematics. The International Mathematical Union awarded the Fields Medal to Professor Witten because of the Jones polynomials.
To explain the Chern-Simons theory, this formula derived quantum invariants and had a profound impact on the world of pure mathematics."
"But topological quantum field theory is also of great significance in mathematics, and is related to knot theory, 4-manifolds in algebraic topology, modulus spaces in algebraic geometry and other branches."
"The 4-dimensional topological Yang-Mills theory. Although the action functional in it contains the space-time metric gαβ, after the topological distortion, the theory becomes metric independent. The independence of the system stress-energy tensor t from the metric depends on
It depends on whether the brst-operator is closed."
The white boy looked at Cheng Hao in front of him seriously and said.
Regarding this point, Cheng Hao understood.
He had to admit that topological quantum field theory was indeed of sufficient significance in the field of mathematics, at least in topology and algebraic geometry.
"Indeed, topological quantum field theory also has extremely important significance in the field of mathematics."
Cheng Hao shrugged.
The white boy nodded, did not continue to say anything to Cheng Hao, and turned to leave.
"Wait a minute, what's your name?"
Cheng Hao looked at the white boy in front of him curiously and asked.
He was quite curious about this guy. There are not many such serious guys these days. He just said what Professor Witten's best academic achievements were.
In the end, the boy in front of me heard it, and he actually stood there and argued with me for a long time. This is also quite rare!
At this time, the boy in front of him slowly raised his head, looked at Cheng Hao, and said calmly.
"My name is John Wilson."
Wilson looked at Cheng Hao in front of him and said.
Hearing his words, Cheng Hao nodded, smiled and said to Wilson in front of him: "Hello, Wilson, my name is Cheng Hao."
"Cheng Hao?"
Upon hearing Cheng Hao's name, Wilson's expression finally changed. He looked at Cheng Hao with a hint of surprise in his eyes.
"You are the Chinese mathematician who solved Zhou's conjecture and then solved the twin prime conjecture??"
"Yes, it's me."
Cheng Hao smiled, looked at Wilson in front of him and said.
"Can you tell me that in line 79 of your paper, in the discussion of Mersenne numbers, n=(2n,m) is directly and abruptly mentioned, thus obtaining that the even-order cyclic group g has a unique 2-order element
a^n, I don’t quite understand this line..."
Wilson looked at Cheng Hao in front of him with probing eyes.
Wang Yiming next to him almost collapsed when he saw the scene in front of him.
"Junior, let's go! Your luggage is not light!"
Wang Yiming smiled bitterly and said to Cheng Hao in front of him.
Hearing Wang Yiming's words, Cheng Hao hesitated for a moment. At this time, Wang Yiming quickly said to Wilson on the side: "This classmate, Cheng Hao, just came to the United States from China. He has been on a plane for almost a day. He needs to rest."
, look, why don’t you wait until tomorrow and ask again?”
Wang Yiming said tentatively towards Wilson in front of him.
Wilson pushed up his glasses, looked at Cheng Hao in front of him seriously and said: "Just in time, I have to go back to the dormitory. I will go to the dormitory with you first. I want to hear your thoughts!"
"Alright!"
Cheng Hao nodded.
After hearing Wilson's words, Wang Yiming suddenly showed a look of helplessness on his face.
This is too difficult!
But there was no other way. Cheng Hao, the client, had already agreed, so what else could he say?
Soon, following the path marked in the student handbook, Cheng Hao came to the downstairs of his dormitory.
"You live in this building?"
Seeing the building in front of him, Wilson turned his head and looked at Cheng Hao curiously and asked.
"yes!"
Cheng Hao nodded.
"I live here too."
Cheng Hao: "…………"
Wang Yiming: “…………”
No, brother, can you ask which building we live in, and then say, don’t you know how to chat?
After walking for so long, you walked downstairs and told us, you live here too, do you have any serious illness?
Cheng Hao rolled his eyes in his heart.
"Which floor is it?"
Cheng Hao was a little helpless to complain, but he still asked Wilson in front of him.
"Third floor."
"I'm on the third floor too!"
Cheng Hao was stunned again. He lowered his head and glanced at his key, which read Room 302.
"It seems that we are neighbors!"
Wilson looked at Cheng Hao in front of him seriously and said.
