Chapter 183: Met an acquaintance?
Xu Qingzhou and Kathleen didn't stay in the cafe for long and left separately. He went back to the hotel to eat, while Kathleen went back to write a paper.
The cafeteria is crowded.
As soon as Xu Qingzhou entered, a scholar came up to talk to him: "Mr. Xu, I am from Columbia University. I am currently engaged in research on the Riemann Hypothesis. Is Mr. Xu interested in cooperating?"
"Sorry, I don't have much idea about the Riemann Hypothesis."
Xu Qingzhou declined politely.
The other party was unwilling to give in: "Mr. Xu, we have made considerable progress. If you are willing to join, we can work together after the results are available."
Xu Qingzhou shook his head, said sorry, and left.
Later, during the 20 minutes of eating, Xu Qingzhou received 5 invitations, all asking if he wanted to join their research project.
The cakes drawn by these people were too round for him to catch. Any progress that has been made is all false. The 99% possibility is that he wants to drag him, who has the title of "prover of Kramer's theorem", over to ask for funding from the superiors.
Once you get the money, you can get whatever results you want. Whether it's right or not is another matter later. To take a step back, even if we can't get results, we can finally say, can what we mathematicians do be called cheating? It’s just that the results were unsatisfactory.
He finished the meal in several bites and hid in his room.
In front of the desk.
Xu Qingzhou took out all the manuscript papers. From the time he came into contact with the twin prime number conjecture to now, there are more than a hundred manuscripts alone. After exhaling, he calmed down again and planned to go through all the ideas one by one.
Yes, he has figured it out. Now that he has come to this point, there is no reason to overturn the existing results and go back and follow Zhang Yitang's method again.
Zhang Yitang's method was to optimize the GPY sieve method and proved that there are infinite pairs of adjacent prime numbers with a distance of less than 70 million. After that, although mathematicians followed his ideas and upgraded the sieve method, even Terence Tao They say the chances of being able to prove it are slim.
He used the Selberg sieve method and made corresponding improvements and optimizations.
For example, on the basis of requiring λ to be zero when d>R, it is also required that λ should be zero when d has a large prime factor. At the same time, the Selberg parameter is changed to a more flexible polynomial function.
London time 23:50.
Xu Qingzhou looked at a pile of manuscripts and still had no clue, so he simply packed them up and went to bed.
In Room 802, Academician Xu Shihui was still reading materials and memorizing data from time to time. Suddenly, a cell phone ringtone rang in the silent room.
Academician Xu glanced at the number, answered the call, took off his reading glasses, and greeted with a smile: "Lao Gu."
Professor Gu Zhizhong's voice came: "Old Xu, how have you been these past few days? I've gained a lot?"
Academician Xu smiled: "Well, many problems have been solved, so I didn't run away in vain. However, you, an old guy, didn't call me just to care about me."
"We have been friends for decades, why can't we still care about you?"
"Humph, I don't know about you yet?" Academician Xu chuckled twice, "Let's get down to business, your precious student stole the show today."
"Oh? Will his report be given in a few days?" Professor Gu was a little surprised on the other end of the phone.
Academician Xu told what Xu Qingzhou had discussed with Professor Maynard on the stage today. He paused and then wondered: "Why would you let such a good young man engage in physics?"
He and Professor Maynard had the same idea. A person's energy is limited. If he goes to the Institute of Physics, he will naturally not be able to devote 100% to the research of mathematics.
"It's his choice."
Professor Gu's helpless voice came over the phone, and he added: "When the experiments at the Institute of Physics come to an end, I will ask him which direction he plans to take in mathematics."
Academician Xu smiled: "I heard that he is currently studying the twin prime conjecture."
Professor Gu was obviously stunned for a moment, and said with a smile: "I used to worry that he would be under a lot of pressure from studying physics and mathematics, but I didn't expect that this kid would put a huge mountain on his shoulders." Academician Xu also sighed with emotion: "Yes. Ah, Lao Gu, the twin prime number conjecture, do you think he can come up with any new results? "
Professor Gu thought for a while and said: "Although this kid's talent is really terrifying, I can only say that it is very difficult. The twin prime conjecture is much more complicated than Kramer's theorem. There are so many mathematicians in the world studying it, but it is not possible. Just get that stuff out.”
Academician Xu sighed and said with some emotion: "It's good for young people to be aggressive."
"Yeah, let him try."
It's good to have results, but not having results can also let young people know that they shouldn't be anxious about anything, especially when it comes to research, and they should take their time, be calm, and sit on the bench.
Professor Gu said: "Okay, Lao Xu, it should be 12 o'clock over there now. You have to go to bed early. Even though you are old, you still stay up late like the young ones."
"Read the information for a while and then go to bed." Academician Xu nodded.
"When you come back, I'll treat you to tea."
"I'm just waiting for your words. I'll drink the tea from the small jar in your cabinet first."
"Okay, Lao Xu, you old guy has been thinking about it for a long time, right?"
In the next few days, Xu Qingzhou was immersed in the enthusiastic atmosphere of mathematical research.
During this period, I received an invitation from Professor Maynard to attend an exchange meeting on prime numbers, and gained a lot.
These are the top scholars in the field of prime numbers in mathematics. They have comprehensive knowledge and extensive knowledge. Xu Qingzhou gained a lot of knowledge during the conversation.
For example, mathematicians from Sweden plan to try to calculate the largest twin prime number by using hardware resources such as high-performance computer clusters and large-capacity storage devices.
Professor Maynard and several mathematicians improved Zhang Yitang's method to optimize the upper bound of the prime number interval to describe the distribution of prime numbers.
But it is extremely regrettable that there is not much that Xu Qingzhou can learn from.
Of course, he also saw a lot of interesting things during this period. In addition to the previous Goldbach's conjecture, someone also announced that he had proved the twin prime conjecture.
This person used Euclid's method of proving that there are infinitely many prime numbers to prove that there are infinitely many twin prime numbers.
Xu Qingzhou saw counterexamples at a glance.
In addition to attending lectures and communicating with participating scholars, he basically stayed in the hotel to calculate the twin prime number conjecture, and declined the invitation of senior brother Zhao Zhenglai and Kathleen to go to the bar.
Three days flew by and it was April 2nd.
At 9 o'clock in the morning, Xu Qingzhou finished breakfast, picked up the prepared report and walked towards the report hall.
Today, the sun is very bright, and the orange light shines on the ancient city. Pedestrians walk leisurely on the road, and occasionally there is the sound of cars passing by in the distance, and then it returns to silence.
Xu Qingzhou was lowering his head and meditating. Over the past few days, the feeling that he was about to grasp the truth became clearer and clearer.
"handsome guy!"
A shout rang out.
Xu Qingzhou looked up and took his mind off his calculations, and saw two people standing at the corner in front of him. The girl looked surprised, and the boy looked at him gloomily, seeming a little unhappy.
Oh, it's those two people on the plane.
