Chapter 215: Not easy for a genius

The gains of Lu Zhou in these days can be said to be quite large.

Not only at the academic level, but also at the level of connections in the academic circle.

Many people who had met him before in newspapers, news, and even textbooks stood in front of him, and it felt strange.

For example, Heim Brezi, a member of the French Academy of Sciences and a foreign member of the United States and Chinese Academy of Sciences. The "Functional Analysis" read by Lu Zhou is his book. Lu Zhou was impressed by the description and explanation of Sobolev space.

The old gentleman from France was very funny and enthusiastic, especially when he heard that Lu Zhou had read his works, he was even more enthusiastic about Lu Zhou. He repeatedly stated that if he had the opportunity to come to France, he could Go to Paris Normal University to find him.

He has a collection of interesting books, including even Euler's manuscripts.

In addition to this enthusiastic and cheerful old Frenchman, Lu Zhou also met Tao Zhexuan, a genius well-known in Chinese mathematics.

Unlike the impression, this math genius who often “points to the mountains and rivers” on blogs is unexpectedly a stingy, laughing person in reality.

In addition, he looks younger than Lu Zhou's imagination, and he can't see it at all. This is actually seventy-five years later, and this year is already forty.

Because he was born in Australia, he does not speak Mandarin. Although he speaks Cantonese, it is uncomfortable that Lu Zhou cannot understand, and the two can only communicate in English with regret.

On the fourth day of the academic conference, after the one-hour lecture, Tao Zhexuan invited Lu Zhou to visit his office.

At first, the two talked about domestic and foreign affairs, and soon they talked about academic issues.

After exchanging a few words, Lu Zhou couldn't help feeling in his heart.

I have to admit that this guy is indeed a genius in the field of mathematics! His research is spread across all areas of mathematics. He doesn't necessarily excel at many things, but you can hardly find things he doesn't.

And just in September of this year, he cracked the 80-year-old Eldish difference problem. This is a classic problem in the field of number theory and discrete analytical mathematics, and outside his field of research.

It is just that it is not as important as Polignac's conjecture, so the limelight was overshadowed by the rising star Lu Zhou.

"Are you studying Goldbach's conjecture?"

Lu Zhou asked unexpectedly: "Yes, have you studied it?"

"I tried it, just at the beginning of this year, but I soon realized that it wasn't something I could solve. I'm still better at researching the partial differential equations and harmonic analysis," Tao Zhexuan smiled embarrassed, generous. Acknowledged his shortcomings and continued, "At the time, I saw your paper in the annual mathematics book, and I was greatly inspired by the topological principles of the sieve theory. I thought if I could improve it, say no "Junner can prove the difficulties of this century on the basis of Chen's theorem ... Unfortunately, the result."

"Is the Sifa method still inaccessible?" Lu Zhou asked with a frown.

The theory of sieve method supplemented by topology is originally one of his alternatives. Tao Zhexuan's statement is undoubtedly bad news for him.

"No way ... or I didn't get through," Tao Zhexuan shook his head, picked up the ball-point pen and wrote a few lines of formula on the paper.

[∑ | s (αm) | 2? ∑ | αn | 2, where αn takes any number]

[S (α) = ∑an, nz, a1 ... an is a set of real numbers with good distribution of module 1 ...]

[……]

Staring at the calculations on the paper, Lu Zhou touched his chin, his brows froze, and lost his thoughts.

Tao Zhexuan stopped his pen and said with a smile: "I'm a bit arrogant. This method is still invented by you."

"No, it is Professor Zellberg who introduced topology theory into the large sieve method. I just did a little work on his basis, and you obviously made a lot of improvements." Lu Zhou smiled. , Continue to look at the expression on the paper, and thoughtfully, "Since am is a good distribution, why not take r ^ (-1) · Σ | s (αm) | 2 as ∫ | s (α ) | 2dα Riemann sum? "

Tao Zhexuan's eyes lightened slightly: "What then?"

"The value r = 1, we can get from the Cauchy-Schwartz inequality ..." It is unclear that Lu Zhou picked up his pen and wrote his thoughts on paper.

【| S (α1) | 2n∑ | an | 2】

Tao Zhexuan's eyebrows frowned slightly and thoughtfully said, "Your idea is very interesting ... We need to find a value of n (δ), and we can find it?"

Lu Zhou nodded, touching his chin, "Yes,? Will not be much larger than n + δ ^ (-1), but the trouble lies in n."

The silence continued for a while, and the two looked up at the same time, smiling at each other.

Smile, a bit bitter by accident.

Sure enough, it still doesn't work!

Throwing the ballpoint pen on the table, Tao Zhexuan sighed and said with emotion.

"Goldbach's conjecture is really too difficult. Maybe it will be another 10 years, or even 20 years. Maybe you can try the round method. To be honest, Da Sifa ’s path may really not work."

Lu Zhou shook his head: "I'll take the time to study it, but I haven't completely given up on Sifting. Maybe it still has potential that we didn't realize."

"Would you like to teach at Berkeley, the environment here is not bad, we can study this subject together ... if you don't think I'm stupid." Tao Zhexuan smiled.

Lu Zhou: "..."

Yes, the 230 iq thinks he is too stupid. What do you do for ordinary people with iq floating around 100?

For the first time, he realized that talking to someone who was too modest was also a headache.

Lu Zhou coughed and said, "My PhD has not graduated yet, and I will probably go to Princeton to study for a Ph.D. early next year."

"You haven't graduated yet," Tao Zhexuan gave a surprised look at Lu Zhou. "Well ... Hua Guo's university is really strict."

Lu Zhou: "I did a master's degree early this year."

"Oh, that's understandable," Tao Zhexuan smiled comprehensibly. "It was also when I was studying for a master's degree. I can graduate in half a year. The instructor has to keep me for one year before letting go."

Then, Tao Zhexuan wrote his mailbox on the previous draft paper, handed it to Lu Zhou, and said with a smile: "Contact me by email in the future. If there are any new findings, I will talk to you again."

"Ok."

Lu Zhou nodded with a smile, put away the draft paper, left his own mailbox on another paper, and then said goodbye to Tao Zhexuan.

When walking towards the hotel, Lu Zhou had been thinking about the problem just now and couldn't understand it.

Thinking about it, my stomach became hungry.

He took out his mobile phone and watched the time. Seeing that there was still a little time before dinner, he turned and walked into a rib restaurant on the street.

After ordering a rib set, Lu Zhou took out the change of 19 dollars and put it on the counter, and found a place to sit down.

Everyone said that American meat was cheap, and he didn't always feel that it was cheap.

A rib is $ 19, which translates to 110 if converted to rmb.

Just as he thought about it, a somewhat thin waiter, holding a plate as wide as a washbasin, put it on his table with a little effort.

Seeing what was on the plate, Lu Zhou's eyebrows twitched fiercely.

Good guy, he thought the ribs here were the kind of ribs he had seen in a Western restaurant, but he never expected that there was a whole rib on the plate! For soup, there are enough cauldrons!

Add a pound of roasted potatoes with butter and sour cream, a bowl of Mexican stewed red beans, and a mysterious thick soup ...

Take a look ~ www.wuxiaspot.com ~ This meat is really cheap.

However, this is obviously not a portion that one can eat ...

He finally knew why there were so many fat people in the United States.

"Sir, are you satisfied with the food?"

When heard of someone asking, Lu Zhou suddenly remembered that he didn't seem to give a tip, so he took out two dollars of change from his bag.

But just then, he suddenly found out that the waiter ...

Seems familiar?

Lu Zhou handed the tip to her, asking in confusion: "Are you working here?"

"Um." Willa nodded embarrassedly.

"Are there no scholarships?"

Lu Zhou used to take a part-time job for tuition and living expenses, so he didn't find it bad.

But to his surprise, he remembers that American scholarships are well applied, not to mention this imo gold medal sender, as long as he is not too hobby, it is not difficult to finish college without spending a penny.

Willa obviously didn't expect to meet Lu Zhou here, she smiled embarrassedly and whispered, "Scholarships are available ..."

If it is to save money for travel, or to work and experience life, you will definitely say it generously.

Seeing that she did not continue to talk, Lu Zhou probably guessed that most of the reasons were similar to her own, so she switched off this heavy topic.

"Are you Russian?"

Willa's expression was a bit subtle and she shook her head.

Seeing her slightly awkward expression, Lu Zhou always felt ...

I seem to have asked a question that should not be asked?

Just then, someone called her name in the kitchen.

When Vera heard her name, she quickly replied, bowed quietly and said sorry to Lu Zhou, and hurried back in a hurry.
