Chapter 212 Someone is causing trouble?
11:40 p.m.
Although Xu Qingzhou was a little unfinished, he had to stop, but he also added the contact information of more than a dozen professors, including Mr. Wang Yiyuan, who had benefited him a lot.
After lunch, I returned to the hotel, sent a message to the school beauty Song, and reported my situation. Then I sorted out the knowledge points for the morning, rested for half an hour, and then walked slowly to the venue.
The afternoon report will be from Professor Luo Yuanming of Sun Yat-sen University, analyzing the content of 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, which made it impossible to communicate well like other discussion groups.
He simply followed the example of other discussion groups and wrote down the topics: Kramer's theorem and prime number gap discussion.
On the 22nd, I will give a report on the twin prime conjecture, so I can put this aside for now.
In the afternoon, Mr. Wang Yiyuan was still there.
Xu Qingzhou focused on explaining the details of the construction of his mathematical model, and while taking a break to drink tea, he chatted with Mr. Wang again.
"I have also been thinking about whether the powerful computing power of modern computers can be introduced into the study of prime number intervals, and through large-scale data simulation and algorithm optimization, we can discover the potential patterns of prime number intervals."
Looking at Xu Qingzhou, Mr. Wang nodded approvingly and said in a casual tone: "After all, data is an important cornerstone of mathematical research, and modern computer technology is our weapon for mining data treasures."
Xu Qingzhou said modestly: "I only solved the problem by standing on the shoulders of my predecessors."
Mr. Wang asked: "Now that the twin prime conjecture has been proved, are you ready to conquer the Polignac conjecture?"
"I have this idea." Xu Qingzhou nodded.
"It's a good thing to be motivated. Our Xia Kingdom needs more young people like you."
As he said this, Mr. Wang was helpless: "Unfortunately, I am only interested in the field of prime numbers and my research time is relatively short. I cannot provide you with much help in this regard."
"You have given me a lot of inspiration." Xu Qingzhou shook his head, not as a compliment. The three places pointed out by the old gentleman can all be modified accordingly.
Mr. Wang smiled and said: "However, in other matters, my old bones can still use some residual heat."
"Other places?"
Xu Qingzhou was confused and didn't understand what it meant.
Mr. Wang smiled without saying a word and stood up with the cup in hand, "Okay, as we get older, we will get tired after spending a little energy."
"I'll see you off." Xu Qingzhou stood up and walked the old gentleman to the door.
"No, you go back to work."
The old gentleman slowly disappeared at the top of the stairs.
Xu Qingzhou shook his head helplessly. Fortunately, he was not a person who easily got entangled. Although he was curious about what the old man said could help him, he quickly fell into discussions with other people after failing to think through it.
Two days passed in a blink of an eye.
Xu Qingzhou had a very fulfilling life and attended two seminars on analytic number theory. One was about the properties and applications of the average value of arithmetic functions, the divisor function σ_k(n) (representing the sum of all positive divisors of n raised to the kth power), Analyze its average behavior over different intervals.
Another session uses Peron's formula to convert the estimation problem of the summation function into the zero point problem of the complex variable function.
In addition to this, I also completed the data analysis of quantum optical frequency comb during this period and completed another paper.
April 22nd.
At 8:20 in the morning, Xu Qingzhou adjusted his clothes in front of the mirror. Perhaps because of the addition of a thirty-year-old soul in his body, the childishness on his face was gone, and he was more mature than his peers.
"Handsome." Xu Qingzhou gave himself a fair comment and went out with his computer.
His report will be scheduled for 9 am.
However, in addition to the Xia people, many international friends came this time. Small seminars can be communicated in English, but large reports are not suitable.
Therefore, the organizing committee specially arranged a question and answer session in Classroom 209. After all, even if foreigners come to the lecture hall, they can probably understand a formula, and the rest of the time they are basically listening to scriptures.
After breakfast, Xu Qingzhou was a little surprised when he arrived at the lecture hall and saw that it was already full. It was much more crowded than the previous lectures.
Apparently everyone is very interested in the twin prime conjecture.
Professor Feng and the others were also there. Xu Qingzhou nodded as a greeting. Then with the help of the staff, he connected the computer and played the ppt used in the report.
Looking at the young man on the stage, Professor Feng couldn't help but smile. In the morning, Lao Gu called and asked about Xu Qingzhou's situation.
Lao Gu is overly worried, this little guy is very skilled.
I heard from Lao Gu that Xu Qingzhou was still doing physics stuff.
What a waste of talent. With this talent, if you delve deeply into the field of mathematics, your future achievements will definitely not be small.
On the stage, preparations were over, and the staff prompted that it was time to start. Xu Qingzhou pressed the play button, and the PPT popped up on the first page. He first gave a general overview of the research content.
"When solving the twin prime conjecture problem, I repeatedly studied the achievements of my predecessors in this field, the methods of Mr. Chen Jingrun, Mr. Zhang Yitang, etc."
Xu Qingzhou spent 3 minutes sorting out the content, and then quickly entered the key content and selection of screening methods.
Tell about how you improved the sieve method, your knowledge about Siegel's zero-point estimate, L function, automorphic form, etc., and how to change the Selberg parameter into a more flexible polynomial function.
"This is a key point, π(x)~L(s,\chi)=\sum_{n=1}^{\infty"
"Of course, at the beginning, we cannot know the growth rate of π2(x) from this asymptotic formula. Therefore, we must first adjust the product on the right side to turn this side into a convergent quantity.
"That is, find a product of a known asymptotic expansion."
“Next, quadratic forms need to be introduced into the sieve method.”
As he spoke, Xu Qingzhou picked up the marker next to him and wrote down the corresponding formula.
At 10 o'clock, the report ended. When it came to the question and answer session, the first person to raise his hand was a professor in his 40s.
"Page 45, Section 3, I noticed that you directly calculated the main items of the sieve method here, but did not explain it. Can you please explain it in detail?"
“According to the original formula, it is impossible to directly obtain the asymptotic formulas of the principal terms M and M, but through some technical scaling we found that we can connect it with the principal terms M and M of the original Selberg sieve method, and thus use the inequality Combine the two.”
"The formula is"
Questions, answers, questions, answers, everything went smoothly. Someone asked a more sharp question, but it was within the normal range. After Xu Qingzhou finished speaking, the other party slowly sat down.
Until the end, Xu Qingzhou announced the end, bowed slightly to the audience, and began to pack his things amidst strong applause.
"Classmate Xu Qingzhou, something serious has happened!"
Ren Chujun came in against the crowd, looking anxious, and quickly arrived in front of Xu Qingzhou.
"What's wrong?" Xu Qingzhou asked.
Ren Chujun looked very nervous: "There are people outside who are preparing to falsify your twin prime number conjecture!"
Oops, someone started causing trouble?
