Chapter 212: Is someone stirring up trouble?

11:40 AM.

Although Xu Qingzhou was a bit unfulfilled, he had to stop. However, he had added the contact information of more than a dozen professors, including the old gentleman Wang Yiyuan, who had benefited him greatly.

After lunch, he returned to the hotel, sent a message to School Beauty Song to report his situation, then organized the knowledge points from the morning, rested for half an hour, and then went to the venue slowly.

The report meeting in the afternoon was by Professor Luo Yuanming from Sun Yat-sen University, with content on analytic number theory.

After listening to the lecture, Xu Qingzhou went directly to Classroom 209 and wrote down the topic of the group discussion at the door.

After the morning exchange meeting, he also discovered a problem: there were too many people, making it impossible to communicate properly like other discussion groups.

He simply learned from other discussion groups and wrote down the topic: Discussion on Cramer's Theorem and Prime Gaps.

There would be a report on the twin prime conjecture on the 22nd, so this could be put aside for now.

Xu Qingzhou shook his head helplessly. Fortunately, he wasn't someone who easily dwelled on things. Although he was curious about what this old gentleman said he could help him with, after thinking it through, he soon sank into discussions with others.

Read! {

"No need, you go back and get busy."

Until the end, Xu Qingzhou announced the conclusion, bowed slightly to the audience, and began to pack up his things amidst intense applause.

"In other words, find a product with a known asymptotic expansion."

Besides this, he also finished the data analysis of the quantum optical frequency comb during this period and completed another paper.

"Next, it is necessary to introduce quadratic forms into the sieve method..."

Xu Qingzhou was puzzled and didn't understand what it meant.

"You have already given me a lot of inspiration." Xu Qingzhou shook his head; it wasn't flattery. The three places the old gentleman pointed out could all be modified accordingly.

"I do have this idea." Xu Qingzhou nodded.

On stage, preparing to end, the staff prompted that he could start. Xu Qingzhou pressed the play button, the PPT jumped to the first page, and he first gave a rough overview of the research content.

His report meeting was scheduled for 9:00 AM.

As he spoke, Xu Qingzhou picked up the marker next to him and wrote down the corresponding formula.

"Of course, here at the beginning, we cannot know the growth rate of π2(x) from this asymptotic formula. Therefore, first, we must adjust the product on the right side to turn this side into a convergent quantity."

"According to the original formula, it is impossible to directly obtain the asymptotic formula for the main term m, m, but through some skillful scaling, we found that it can be linked to the main term m, m of the original Selberg sieve method, thereby combining the two through inequalities."

Another session was using the Perron formula to transform the estimation problem of the summation function into a problem of the zeros of a complex function.

Heard from Old Gu that Xu Qingzhou was still doing things in physics.

"The formula is..."

After finishing breakfast and arriving at the report hall, seeing that it was already full, Xu Qingzhou couldn't help but be somewhat surprised; the number of people was much higher than the previous few report meetings.

Old Gentleman Wang asked: "Since you have proved the twin prime conjecture, are you preparing to conquer the Polignac conjecture next?"

Xu Qingzhou had a fulfilling time. He attended two seminars on analytic number theory. One was about the properties and applications of the mean value of arithmetic functions, the divisor function o_k(n) (representing the sum of the k-th powers of all positive divisors of n), analyzing its mean value behavior in different intervals.

Xu Qingzhou said modestly: "I also just solved the problem by standing on the shoulders of predecessors."

In the afternoon, Old Gentleman Wang Yiyuan was still there.

!.

Obviously, everyone was very interested in the twin prime conjecture. He recounted how he improved the sieve method, knowledge about Siegel zero estimation, L-functions, automorphic forms, etc., and how to change the Selberg parameters into more flexible polynomial functions. "This is a key point, π(x)~l(s, \chi)=\sum_{n=1}^{\infty..."

Wasting talent. With this talent, if he deeply cultivated the field of mathematics, his future achievements would definitely not be small.

Old Gu was overthinking it; this little guy was very proficient.

"Other places?"

Xu Qingzhou focused on explaining the details of his mathematical model construction. Taking advantage of the break to drink tea, he chatted with Old Gentleman Wang again.

Therefore, the organizing committee specially arranged a Q&A session in Classroom 209. After all, even if foreigners came to the report hall, they could probably only understand a formula; the rest of the time was basically listening to heavenly books.

Xu Qingzhou used 3 minutes to sort out the content, then soon entered the key content: the choice of sieve method.

At 10:00, the report meeting ended. In the Q&A session, the first to raise a hand was a professor around 40 years old.

"Having drive is a good thing. Our Xia Nation needs more young people like you."

However, besides Xia Nation people, many international friends also came this time. Small seminars could use English for communication, but large reports were not suitable.

Old Gentleman Wang smiled and said: "However, in other matters, this old bone of mine can still exert some residual heat."

Professor Feng and the others were also there. Xu Qingzhou nodded, which counted as a greeting, then connected his computer with the help of the staff and played the PPT to be used for the report meeting.

Questions, answers, questions, answers—everything went very smoothly. Someone asked somewhat sharply, but it was all within the normal range. After Xu Qingzhou finished speaking, the other person also sat down slowly.

"I'll see you off." Xu Qingzhou stood up and sent the old gentleman to the door.

Two days passed in a flash.

As he spoke, Old Gentleman Wang was helpless: "It's a pity, I'm only interested in the prime number field, and my research time is relatively short, so I can't provide you with too much help in this regard."

April 22nd.

Old Gentleman Wang smiled without saying a word, stood up with his cup: "Alright, I'm old, and I get tired after consuming a little energy."

"Page 45, Section 3, I noticed that you calculated the main term of the sieve method directly here, but didn't provide an explanation. Can you please explain it in detail?"

The old gentleman disappeared slowly at the stairwell.

Looking at the young man on stage, Professor Feng couldn't help but laugh in his heart. Old Gu had called in the morning to ask about Xu Qingzhou's situation.

Looking at Xu Qingzhou, Old Gentleman Wang nodded approvingly and said in a chatty tone: "After all, data is an important cornerstone of mathematical research, and modern computer technology is the sharp tool for us to dig for data treasures."

"I have also been thinking about whether it is possible to introduce the powerful computing power of modern computers into the study of prime gaps, and discover the potential laws of prime gaps through large-scale data simulation and algorithm optimization."

"When solving the twin prime conjecture problem, I repeatedly studied the achievements of predecessors in this field, the methods of Mr. Chen Jingrun, Mr. Zhang Yitang, and so on..."

At 8:20 AM, Xu Qingzhou tidied his clothes in front of the mirror. Perhaps because of the extra soul in his thirties in his body, the immaturity on his face had faded, and he had a bit more maturity than his peers.

"Handsome." Xu Qingzhou gave himself an objective evaluation, picked up his computer, and went out.

"Student Xu Qingzhou, something terrible has happened!"

Ren Chujun came in against the crowd, her expression anxious, and soon reached Xu Qingzhou.

"What's wrong?" Xu Qingzhou asked.

Ren Chujun's expression was very nervous: "Someone outside is preparing to falsify your twin prime conjecture!"

*Huo*, someone started stirring up trouble?
