What Lu Zhou had managed to obtain over the past few days was huge.
Not just in the academic field, but more in the sense of social networking.
Lu Zhou met many people he had read about in textbooks, newspapers, and articles. The feeling itself is incredible.
Heim Brenzi, an academic from the French Academy of Sciences. Lu Zhou had read Brenzi's "Functional Analysis" textbook, in which Brenzi's explanation of Sobolev's space made a lasting impression on Lu Zhou.
This old man from France was very funny and enthusiastic. Especially after he heard that Lu Zhou read his work, he was even more friendly towards Lu Zhou. He repeatedly said that if Lu Zhou ever went to France, he could look for him.
Brenzi has an interesting collection of manuscripts, including one from Euler.
In addition to this warm and cheerful old man, Lu Zhou also met the Chinese mathematical genius, Tao Zhexuan.
Lu Zhou felt like Tao Zhexuan was different personally. He did not expect that he would become a humorous and friendly man.
Also, he looked younger than Lu Zhou had imagined. Lu Zhou would never have guessed that Tao Zhexuan was in his forties.
Since she was born in Australia, she does not speak Mandarin. However, he could speak Cantonese, but unfortunately, Lu Zhou could not understand it. Therefore, they had to speak in English.
The fourth day of the conference, after the hour-long report ended, Tao Zhexuan invited Lu Zhou to visit his office.
The two began to talk about academic issues.
After exchanging a few words, Lu Zhou could not help but think.
I have to admit. This guy is a math genius! His field of study is in all areas of mathematics. He may not be good at everything, but there is rarely anything he does not know.
In September of this year, he solved the 1980 Erdos problem unsolved. These are problems of classical number theory and problems that are outside the realm of Zhexuan Taoist research.
However, it was not as important as Polignac had expected, so his highlight was stolen by Lu Zhou.
"You're studying Goldbach's conjecture?"
Lu Zhou asked, "Yes, you've researched before?"
Tao Zhexuan smiled and admitted his shortcomings, “I tried, at the beginning of this year. I soon realized I couldn't finish it. I better study two-way partial differential equations and harmonic analysis. "
He then continued, “I saw your thesis in Annual Mathematics.I was very inspired by the topological sieve theory that you use.I think it might be able to solve Chen's theorem ... However, the result is regrettable. "
Lu Zhou asked, "Did the sieve method not work?"
Tao Zhexuan sounded pessimistic as he replied, "It didn't work out ... At least I can't make it work."
Tao Zhexuan shook his head and started writing on paper.
[∑ | S (m) | 2≤∆# | | 2, where 2n takes random numbers]
[S () \= (2nd), e (x) \= e ^ (2nd) .M, N∈Z, a1 ... an is a well-distributed set of 1 modulo real numbers ..]
[...]
Lu Zhou looked at the formula on the paper and rubbed his chin. Then he thought hard.
Tao Zhexuan stopped writing and said, “I only read about this method. You are the one who invented this method. "
“No, Professor Zellberg was the one who originally introduced topology into the sieve method. I've just made some minor improvements, and you're obviously making some major improvements, ” Lu Zhou said with a smile as he looked at the newspaper. He then said, “Because I am well distributed, why not treat R^ (- 1) ∑ | S (m) | 2 as ∫ | S () | ” 2) 2d Riemann
Tao Zhexuan's eyes sparkled. He then said, "Then?"
"Value R \= 1, we can get from Cauchy-Schwartz inequality ..." said Lu Zhou. He couldn't explain it in words, so he picked up a pen and started writing on paper.
[| S (1) | 2≤Nalue | an | 2]
Tao Zhexuan said, "Your idea is interesting ... We have to find the value of N ( ⁇ ), then we can find ∆."
Lu Zhou nodded and said, “Ya, but ∆ will not be much bigger than N + ^ (- 1). The problem is in N. "
The two of them raised their heads and looked at each other before they smiled.
However, there was a hint of bitterness in their smiles as this method did not work!
Tao Zhexuan threw the pen on the table and sighed. He started talking, “Circle method is too difficult.It may take decades to complete. You can try the circle method. Honestly, the sieve method may not work. "
Lu Zhou shook his head and said, "I'll research it in my spare time, but I still have hope for the filter method. Maybe it has potential. "
“How about you come to teach at Berkeley? The environment here is good, and we can start a joint research project ... If you don't think I'm an obligation, " said Tao Zhexuan with a smile.
You actually have an IQ of 230. If you are a liability, then what about those with an IQ of 100?
For the first time, Lu Zhou realized that it sucks in the butt talking to people who are too humble.
Lu Zhou said, “I still haven't earned a PhD. I'll probably go to Princeton next year for that. "
"You still haven't graduated?" Tao Zhexuan said as he looked at Lu Zhou. He then said, "Well then ... Chinese universities are very strict."
Lu Zhou said, "I started my master's degree at the beginning of the year."
"Alright then, it's understandable," Tao Zhexuan said. He smiled and said, “When I was doing my master, the same thing happened to me. The supervisor made me stay for a year before I could graduate. ”
Tao Zhexuan wrote his email on a piece of paper and handed it to Lu Zhou. He smiled and said, "Let's keep in touch, I'll contact you if there's a new discovery."
"Good."
Lu Zhou nodded and took the paper. She then wrote her emails on a piece of paper as well.They then split up.
While walking back to the hotel, Lu Zhou continued to think about the problem.
After thinking, he became hungry.
Lu Zhou looked at the time on his phone. It was a little too early for dinner, so she turned around and walked over to the BBQ restaurant.
He then ordered a set of ribs. He then took out $ 19 USD and put it on the table.Once he paid, he went to find a seat.
People say that America is cheap, but he doesn't think so.
$ 19 USD almost $ 110 yuan.
A skinny waitress brought a large plate of food and placed it on Lu Zhou's desk.
When Lu Zhou saw the things on the plate, his eyes twitched.
My God, he thinks it's the ribs he saw on TV. He didn't expect the whole rib rack! That's enough for three people!
On the plate, there is also a baked potato with sour cream, a bowl of Mexican beans, and a mysterious soup.
I think it's worth the price.
But it's definitely not for one person.
He finally knew why everyone in America was so fat.
"Sir, are you satisfied with the food?"
Lu Zhou suddenly remembered that he had not tipped the maid. He then took two dollars out of his pocket.
However, when he saw the maid, he looked familiar.
Lu Zhou put the tip into his hand and asked, "You work here?"
"Yes," nodded Vera in embarrassment.
"Do you have a scholarship?"
Lu Zhou also worked part-time to pay for his tuition and living expenses, so he didn't think there was anything wrong with that.
What surprised him was that he considered American scholarships easy to obtain, especially for IMO gold medalists. It should be easy for him to get a free ride for the title.
Vera had not expected to meet Lu Zhou here. He smiled awkwardly and said, "There's a scholarship ..."
If Vera worked for travel experience or money, she would definitely tell Lu Zhou.
Lu Zhou saw that he did not expand on the reason why he was working, so he guessed that he definitely needed money for tuition.
"You're Russian?"
Vera shook her head.
When Lu Zhou saw his awkward expression, he felt he should not ask.
Suddenly, a chef in the kitchen shouted his name.
Vera quickly turned around and responded. He then bowed to Lu Zhou before he rushed back to the kitchen.
