Chapter 255
The second day.
According to the arrangements of the Chinese Mathematical Society, it should be the time for lectures by major academicians.
However, everyone who came to participate was focused on Wang Donglai.
Whether it is topological group theory or the proof of Goldbach's conjecture, the value is much greater than that of other academician papers.
The Huaguo Mathematical Society also knew this, so it directly postponed Wang Donglai's academic exchange to the next day.
The opening ceremony was held in the concert hall of Makino Normal University, and the academic exchange was moved to a multi-functional hall that can accommodate more people.
Not only the participants came to attend, but also students from Makino University took advantage of the convenient location.
The scheduled academic exchange is only one and a half hours, from ten o'clock to eleven thirty.
The first hour is to explain, and the second half hour is to answer questions and communicate.
At half past nine, the multi-purpose hall was almost full.
When Wang Donglai came in, he didn't feel surprised when he saw this scene, and walked up to the podium calmly.
Behind him is a huge writing board.
Originally, we wanted to prepare a very large projection screen to make it more convenient for Wang Donglai to use PPT.
But Wang Donglai was not going to use PPT, so he changed to a writing pad.
Looking at the people sitting in the audience, ready to listen to his academic sharing, Wang Donglai nodded gently.
Ten o'clock.
Wang Donglai officially started sharing.
Because proving Goldbach's conjecture was entirely a reflection of his own academic ability, all the proof process was in his mind, and there was no need to worry about other issues at all.
As a result, Wang Donglai neither made PPT nor prepared his speech in advance, but just started speaking directly from the script.
"Actually, for Goldbach's conjecture, Mr. Chen has already achieved 1+2 before. I also found some inspiration from Mr. Chen's proof, so I thought about using a new method to prove it, and I found out The knowledge of group theory is of certain help in solving this problem, and it is inspired by the bold guesses of domestic and foreign experts on the proof of Goldbach's conjecture."
"Combining topology and group theory. to one Since then, this method has been called topological group theory by me.”
“Many of the problems in number theory are infinite and cannot be answered even with the help of computers. If we borrow the knowledge of topology, we can simplify the complex..."
On the podium, Wang Donglai did not describe his proof process, but talked about his own ideas and concepts from beginning to end.
Why is it said that there are schools of thought in mathematics? It is because after a mathematics master appeared, the students he led still achieved great results and inherited the academic philosophy of the master.
Wang Donglai has now shown such signs.
Topological group theory is a very practical and valuable branch of mathematics. If Wang Donglai becomes an academician and has the qualification to teach graduate students and doctoral students, and brings out several students who have achieved academic results, he will eventually become an academician. If you become an academician like him.
For two or three generations, it can be said that a new Tangdu Jiaotong University School has emerged in the domestic mathematics community.
Wang Donglai was the founder of the Jiao University School in Tangdu.
If the professors present can abandon their secular views, ignore the age gap between themselves and Wang Donglai, and are willing to follow Wang Donglai and carry forward topological group theory together, they may not be unable to have a place in the academic world in the future.
Many people know these things!
But, until now, no one has taken the lead.
Because they didn’t dare to bet, and they wanted to see more of Wang Donglai’s academic achievements.
Wang Donglai on the stage didn't care what the people below were thinking, and explained completely according to his own ideas.
He has not activated the [Preaching and Teaching] skill. How much they can understand depends entirely on their own academic level.
In this way, Wang Donglai explained very quickly, passing through many things in passing.
Most of the scholars in the audience had their heads down at this moment and quickly wrote down their notes on paper, for fear of forgetting.
When people are focused, they often don’t notice the passage of time.
One hour may seem like a long time, but it’s actually not that long.
Wang Donglai was very fast, controlling the time within just one hour, and explained his ideas and concepts.
This explanation may be of value, indeed it is, but it is only for those professors and academicians who have profound attainments in the field of mathematics.
If you say it has no value, it can barely be called it.
Because for many professors who are just getting started in the field of mathematics, Wang Donglai explained too quickly and did not explain many places in detail. They simply could not keep up, so they did not gain much.
After the explanation, Wang Donglai looked at the people in the audience and said loudly: "Okay, my explanation is over. Next is the exchange and question session. If you have any questions, you can raise your hands to ask. "
Facing the professors and scholars from major universities in the audience, Wang Donglai did not show any timidity and said calmly and generously.
After Wang Donglai finished speaking, a middle-aged man in his forties sitting in the middle immediately raised his hand.
Seeing this, Wang Donglai signaled the person to ask questions.
“Professor Wang, what you just mentioned is to use graph theory to intuitively express the movement between numbers and the relationship between numbers. On this basis, it is regarded as a closed problem. I have some questions. I don’t understand. Can you explain it in detail?”
Hearing the professor’s question, Wang Donglai did not answer immediately. Instead, he glanced at the people in the audience, pondered for a moment, and then said: "The time is limited, and the question time is only half an hour. I will answer this question in detail, but next I hope you can ask some more valuable questions!"
After saying that, Wang Donglai walked to the writing board, picked up a marker and sketched on it.
"The professor's question just now is actually very simple. Since it is a closed problem, we can set a maximum closed area 2n*y (n∈N*). Here we use the 2n*y area in the plane coordinate system To express, n is the value on the x-axis, y is the height of the area. "
"In number theory, a prime number is an integer that can only be divided by 1 and itself. It is represented graphically on the plane, as shown in the figure."
While talking, Wang Donglai quickly drew a neat coordinate diagram on the writing board.
“We use x·y and x=2n (n>3) to define a plane even number. Since x=2n, then we set x=n+n=2n (1 “The form of plane even number x·y can be transformed into: x·y=n·y+n·y, as shown in the figure.” As soon as he finished saying this, Wang Donglai's men drew another picture. “Now, let’s go back to thinking about x·y=(n＋n)·y=n·y＋n·y.” “Suppose, it is easy to see that in the interval {1, n} At least one plane odd prime number: pr1=n·y-k1·y (k1≥0 and k 1∈n)" "According to the Portland-Chebyshev theorem: there is at least one plane odd prime number in the {n, 2n} interval: pr2=n·y+k2·y (k2≥0 and k2 ∈n)" "..." "That is, the plane even number x·y is equal to pr1 + pr2." In three minutes, Wang Donglai explained this problem in detail and wrote most of the page on the writing board. The professor who asked the question was initially a little suffocated by Wang Donglai's answer, thinking that he was too arrogant. However, when he saw Wang Donglai hand in hand with the letter and explained the questions he didn't understand in depth, his doubts suddenly disappeared, and then A hint of admiration emerged. “Thank you Professor Wang for your advice!” The middle-aged professor bowed seriously to express his gratitude and said thank you. "You're welcome!" Wang Donglai nodded with a smile and glanced at the many scholars and professors below again. When Wang Donglai glanced at them, many people's expressions became a little strange, as if they were teachers teaching students.
It’s just that these professors who have been on the podium for decades have now become students. Hands were raised one after another and various questions were asked. Because Wang Donglai had previously said that everyone should ask valuable questions, many people cherished this opportunity to ask questions, and the questions asked were all very difficult and key points. Wang Donglai was not worried and immediately went to the podium to explain his ideas and concepts in detail. The atmosphere in the hall is harmonious. After listening to these contents, Huang Yun and other leaders of the Mathematical Society and several participating academicians nodded with satisfaction. And at this time. Wang Donglai, who was on the stage, was also preparing to choose one more person to ask questions and end the questioning. In a remote corner, a man suddenly stood up and shouted in a loud voice: "I have a problem!" The sudden sound made everyone present look away. I went over to see who was speaking so loudly and disrupting the order. Wang Donglai recognized this person’s identity immediately. Suddenly it was Professor Su Jianshe whom he had met before. The corner of Wang Donglai's mouth slowly curled up. He didn't think that Professor Su Jianshe suddenly stood up and really asked questions. Four big words came to mind, the person coming is not good! Things were exactly as Wang Donglai had guessed. Su Jianshe did not wait for Wang Donglai's permission to ask questions. After seeing that everyone's attention had been attracted, he immediately said: "Whether it is the Portland-Chebyshev theorem you just mentioned, or the use of Graph theory is used to express the relationship between numbers, and then group theory is used to prove it. I will not comment on these. What I value more is the topological group theory you proposed, but you did not explain it in detail in the explanation just now. It’s hard for me to believe you.” "Of course, I'm not questioning your academic achievements. The answer will not come until your paper comes out and is reviewed by scholars, professors and top journals around the world." "I'm just I want to say that if Professor Wang really wants to share, he should be more generous instead of hiding it. It is easy for people to misunderstand whether there is something shameful about Professor Wang's proof." "I am a straightforward person, I hope Professor Wang doesn't mind!" Su Jianshe said with a smile on his face. With a kind smile, if you only look at his appearance, most people would think that Su Jianshe is an affable professor. However, everyone in the arena at this moment is not a fool. How could they not hear Su Jianshe's little thoughts.
Moral kidnapping and slander out of thin air. As soon as this question is raised, Wang Donglai can’t answer it no matter how he answers it, and it will leave controversy. At the same time, Su Jianshe removed himself from the incident and acted as if he was harmless to humans and animals. At this moment, the multi-functional hall is extremely quiet. Su Jianshe completely ignored the looks everyone was looking at him. After the list was announced yesterday, he became angrier and angrier as he thought about it. If he misses this time, there will be no next time. This time, he paid too much and too much, all the favors he had accumulated over the years were used up, yet he still shamelessly asked the leader of the school to put in a nice word. If he misses this time, he will have no chance next time. It means that it is impossible for him to select academicians. Thinking of this situation, his heart was filled with hatred for Wang Donglai. Although two people have won this award, in Su Jianshe's view, if Wang Donglai had not been there, he and Chen Zhongming would have won this award. As a result, Wang Donglai suddenly appeared and took away the award that originally belonged to him. How can this not make him hate Wang Donglai? Ever since, there is this scene now. Wang Donglai, who was on the podium, did not become furious or look extremely ugly after hearing Su Jianshe's words. Instead, he laughed. "Professor Su, I just refused your wish to read my paper, why are you so angry." In one sentence, Su Jianshe said so much. The effect is offset, and the counter-general Su is given the opportunity to build an army. Su Jianshe was also a smart person. His expression suddenly changed and he wanted to explain. However, Wang Donglai on the podium didn't give him this chance at all. He had a microphone in his hand and his voice was louder, so he directly suppressed Su Jianshe's voice and said: "You happen to be here, everyone is Scholars and professors from major domestic universities, I have something to announce.” "That is in September, I will officially hold an academic exchange meeting on Goldbach's speculation at Tangdu Jiaotong University, where I will conduct detailed academic exchanges." "At the same time, I will also invite domestic and foreign students Many experts in the field of mathematics congratulate the establishment of the journal of Tangdu Jiaotong University!” “As a member of Tangdu Jiaotong University, I will do my best to publish my paper! It is listed on the mathematics journal founded by Tangdu Jiaotong University. At the same time, everyone is welcome to submit contributions. "
"For your submissions, we will invite experts in the field of mathematics at home and abroad to review them. Academician Qiu and Professor Deligne will serve as review editors, so you can rest assured.” Everyone present was shocked when Wang Donglai said this. No one expected that Wang Donglai would actually prove that Gecai would not publish in top international journals, but stay in China, or in a journal just founded by his own school. The scholars present are also industry insiders, so they know very well that Tangdu Jiaotong University has no mathematics journals at all. So, Wang Donglai is using his paper to pave the way for the journal of Tangdu Jiaotong University! For a time, countless people envied Tangdu Jiaotong University. At the same time, many people were murmuring in their hearts. Wang Donglai could obviously publish in top international journals, but he ended up publishing in a journal he just founded. Is there any problem in this? They don’t believe that someone would be so stupid as not to submit to a top international journal and publish it in China instead. When something goes wrong, there must be a monster. There must be something wrong here. Xu Songyao in the audience had a wry smile on his face at the moment. He did not expect that Wang Donglai would talk about this matter on this occasion. Although he had heard Wang Donglai talk about this matter before, he really didn't expect Wang Donglai to be serious. Here, saying it in front of scholars and professors across the country means that Wang Donglai has little chance to go back on his words. "Congratulations, you Tangdu Jiaotong University have really found a treasure!" Huang Yun looked over and said to Xu Songyao with a look of emotion on his face and a tone full of envy. “Indeed!” Naturally, Xu Songyao would not deny it, but admit it. Just when everyone was shocked by what Wang Donglai just said, Wang Donglai spoke again. The content of what he said this time made the expressions of those present even more complicated.
