Chapter 149 Two Friends
"Dean Li, wait a minute." Seeing that Li Mingzhi was about to leave after finishing speaking, Zhou Ming hurriedly shouted.

Li Zhiming, who had already turned around, saw Zhou Ming calling him to stop him, stopped curiously, turned his head to look at Zhou Ming, and asked him, "What's the matter? Is there anything else?"

"I don't know who the friends Dean Li mentioned who specialize in number theory are? Teacher Wang and Teacher Pan?" Zhou Ming was a little curious about the friends Li Mingzhi mentioned.

Because Zhou Ming knew that although Li Mingzhi said that he did not specialize in the field of number theory, his strength in number theory, especially in the area of ​​analytic number theory, was not bad at all.

After all, Li Mingzhi could understand Zhou Ming's previous proof of the twin prime number conjecture.

"Hey, keep it secret, you'll know when the time comes." Hearing Zhou Ming's question, Li Mingzhi just smiled. It is estimated that Zhou Ming used to play tricks on him before, but now he is also playing tricks on Zhou Ming.

But when Li Mingzhi finished speaking, the smile on his face became more obvious, as if he had thought of something interesting.

"I can still imagine the surprise on their faces when they heard me that someone had proved Goldbach's conjecture, and knowing that the person who proved Goldbach's conjecture was just a young man in his 20s, and this After the young people only took three days to prove it, the look of disbelief on their faces. Haha, it’s interesting to think about it.”

At the end of Li Zhizhi's speech, he simply burst out laughing, and when he said these words, he had already walked to the gate.

"I'm leaving first, and I will notify you in advance when they come over, so I don't need you to send them." Opening the door, Li Mingzhi turned around and said something to Zhou Ming, and he walked out of the room after saying this .

But when Zhou Ming wanted to go out to see Li Zhizhi off, the door had already been closed by him.

After Li Zhizhi left, Zhou Ming walked back to the room, thinking about who the friend Li Zhizhi mentioned was, he felt that his guess just now must be correct, otherwise he really couldn't figure out the theory of logarithms, especially Goldbach's conjecture. In the field of research, besides those two, how many other people in China can be called friends by Li Mingzhi.

However, Zhou Ming was still a little puzzled, because those two were almost ten years older than Li Zhiming, and it seemed inappropriate to call them friends.

Zhou Ming didn't put too much thought into this matter. After all, they were coming over in a few days anyway, so it was pointless for Zhou Ming to make wild guesses without any basis.

After figuring this out, Zhou Ming picked up his cell phone and prepared to call Shen Qingqiu. He would call Shen Qingqiu at night when he was not busy.

And when Zhou Mingzheng called Shen Qingqiu, Li Mingzhi had already gone downstairs. At this time, he was looking through the contacts with a smart phone. After quickly finding a person's name, he gave This guy made a phone call.

"Beep... beep... beep... Hey, Xiao Li, why are you free to call me today?" There were a few beeps on the other end of the phone, and the call was connected not long after.

There was an old voice on the other end of the phone, which was very loud.

Talking loudly on the phone seems to be something that every old person does. This is because the old people are older and the various organs of the body are not as sensitive as young people.

The old people's ears are not working very well. When they talk on the phone, they always feel that the voice of the person on the other side is soft. This makes them think that others can hear them and their voice is also soft. That's why they talk so loudly on the phone for fear that others can't hear clearly. own voice.

"Mr. Wang, let me tell you a piece of good news, a piece of great news. Someone on my side wrote the complete proof process of Goldbach's conjecture." To the old man on the phone who was older than himself, Li Zhizhi didn't beat around the bush, and directly said the most important thing he wanted to say on this call.

The teacher Wang who was communicating with Li Mingzhi at this time is an academician of the Huaguo Academy of Sciences, the former director and director of the Institute of Mathematics of the Huaguo Academy of Sciences, a researcher and doctoral supervisor of the Institute of Mathematics and System Science of the Huaguo Academy of Sciences, Hua Guo Wang Yuan, the first prize winner of the Natural Science Award.

Mr. Wang Yuan was born in 1930. He studied under Mr. Hua Luogeng and is Chen Jingrun's senior brother.

In 1952, Wang Yuan graduated from Zhejiang University. Because of his top grades, he was recommended by Chen Jiangong and Su Buqing to the Institute of Mathematics of the Chinese Academy of Sciences, and was assigned to the number theory group of the same institute a year later.

1956年，他证明了哥德巴赫猜想的“3+4”，之后又先后证明了哥德巴赫猜想的“3+3”和“2+3”。

Then in 1962, he proved the "1+4" of Goldbach's conjecture.

When Chen Jingrun claimed to prove the "1965+1" ​​of Goldbach's conjecture in 2, it was also published in the Science Bulletin in 1966 by his brother Wang Yuan after review.

As for the complete demonstration process of Goldbach’s conjecture written by Zhou Ming, let old Mr. Wang Yuan see that there is really no problem. If he can’t understand it, then I’m afraid there won’t be a few people in China who can understand it. .

The reason why Li Zhizhi told Zhou Ming earlier that he called some friends was because although Li Zhizhi and Wang Yuan didn't communicate much, they usually met and chatted in some meetings.

Wang Yuan seemed very approachable when chatting with Li Zhizhi. Although the age difference between the two was almost twenty, they had a very happy conversation every time they talked.

Wang Yuan and Li Zhizhi are usually referred to as friends, but now Li Zhizhi has something to ask Wang Yuan for help, and he is indeed far inferior to Wang Yuan in number theory, so naturally he called him teacher on the phone.

"What? Goldbach's conjecture proved? Who on your side proved Goldbach's conjecture?"

When Mr. Wang Yuan heard that Li Zhizhi said that someone on his side had already written the complete demonstration process of Goldbach's conjecture, he was as shocked as Li Zhizhi heard the news from Zhou Ming before, but his reaction Not as big as Li Mingzhi.

After all, the two knew different information when they heard Zhou Ming prove his brother Debach's conjecture. Li Mingzhi knew how long it took Zhou Ming to prove Goldbach's conjecture when he heard Zhou Ming call him to tell him about it.

But Wang Yuan only knew that someone had proved Goldbach's conjecture, but he still didn't know anything else. Naturally, he was not as surprised as Li Mingzhi was at that time.

"That's right, it's the young man who I applied for an exceptional employment last summer." Li Mingzhi explained to the old man.

Hearing what Li Mingzhi said, Teacher Wang finally remembered who he was talking about. In a meeting before, Li Zhizhi had talked to them about this young man.

"Oh, so it's him. His name seems to be Zhou Ming, right? Why is he so fast? Last month or last month, the one who proved the twin prime number conjecture was also this young man, right?

It took less than a month or two to solve another conjecture that has plagued the mathematics community for so many years, and it is also Goldbach's conjecture. Solving Goldbach's conjecture is much more difficult than solving the twin prime number conjecture.

Am I really getting old?Are today's young people so powerful? "

Although Mr. Wang knew who Li Zhizhi said was the person who proved Goldbach's conjecture, the doubts in his heart not only did not decrease, but increased.

"Yes, he was the one who proved the twin prime conjecture last time. At that time, I wanted to apply to the superiors for an exception to promote him to a second-level professor. However, I guess there must be people who disagree, so I suggested that he apply for a third-level professor first." Li Mingzhi explained that his words continued to deepen Mr. Wang Yuan's impression of Zhou Ming.

"So it's really him? How old is he this year? He's only in his 20s, right? He has proved two conjectures at such a young age. It's really scary." Li Mingzhi confirmed what he just said to prove Goldbach's conjecture. That young man was indeed called Empress Zhou Ming, and Wang Yuan was also proud of Hua Guo for having such an outstanding young man.

"When did he prove it? Why didn't I hear any rumors before? By the way, what method did he use to prove it? Is it the sieve method? Can the weighted sieve method work?" Soon, Wang Yuan asked Li Mingzhi several questions in succession. In fact, he was most concerned about what method Zhou Ming used to prove Goldbach's conjecture.

When asked by Teacher Wang, Li Mingzhi didn't know what to say.

Li Mingzhi struggled for a while, and finally said truthfully: "This is the reason why I called you this time. In fact, I only received a call from Zhou Ming tonight, and I found out that he completed Goldbach's conjecture. Full argument, at least that's what he told me.

After receiving a call from Zhou Ming and learning that he had proved Goldbach's conjecture, I hurried over there, and when I got to him, I took a look at his manuscript..."

When he said this, Li Mingzhi suddenly stopped. He began to recall the content of the first and second pages he had just read from Zhou Ming's dozens of pages of proof of Goldbach's conjecture, thinking about how to use mathematics The language explained to Wang Yuan what he saw.

And Wang Yuan did not urge Li Mingzhi, he knew that Li Mingzhi must be sorting out the proof process he saw earlier in his mind.

Soon, Li Mingzhi continued: "The original manuscript of his proof process of Goldbach's conjecture was written on sheets of typed paper that were not too large, and the entire proof process had a total of about fifty pages of typed paper. Bar.

When I first started watching it, it felt quite familiar, but after only a few lines, it didn't work.

As for what method he used, I can only see a little shadow of the Brown sieve method from the first few lines of formulas and proofs, but the subsequent proof process is difficult for me to understand. The second page eventually gave up, and even that one or two pages I had a hard time reading.

So, I called you just to ask you to see if there is anything wrong with his proof process, whether it was really proved, or just another wrong proof. "

"You also seem to find it difficult to understand? I remember that you also have some research on number theory?

When Chen Jingrun proved '1+2', you young people rushed to Goldbach's conjecture one after another. Maybe it's because you haven't studied this problem much now, and you have forgotten all the previous knowledge. ? "

Wang Yuan asked a little strangely. In his opinion, although Li Zhizhi's main research field is not Goldbach's conjecture, Li Zhizhi's knowledge in number theory is very rich. Two pages will also feel obscure?

"No, of course I can understand the general proof process. Didn't I understand the proof process of his last article on the twin prime number conjecture?
The main reason is that the methods he used this time are all improved methods, and he omitted many steps in each line. I had to calculate the proof process of each line myself to know whether it was correct. "Li Mingzhi explained.

In fact, Zhou Ming used some improved proof methods in the proof process in his last paper proving the twin prime number conjecture, but the improved proof methods he used that time were not many, and his steps were written It is also clearer than what proved Goldbach's conjecture this time, and it can be understood step by step by a mathematics professor like Li Mingzhi.

"Oh... so that's the case, I understand. It seems that you still don't know whether Goldbach's conjecture has been proved to be successful. You just heard that Zhou Ming said that he proved it, right?"

After listening to Li Mingzhi's explanation, Wang Yuan nodded involuntarily, and he continued: "That's fine, then hurry there as soon as possible. I'll buy the ticket now, and I'll go to your place tomorrow."

"Okay, let me know in advance before you arrive, and I will pick you up." Li Zhiming said.

Just when both of them were about to hang up the phone, Wang Yuan suddenly asked again: "By the way, you can't just invite me alone, right?
I am quite old now, you want me to read through his proof process alone and find out if there are any loopholes, it will not take several months?Who else did you invite? "

"Of course I can't just let you come for the trial alone. I'm going to invite Professor Pan. I'm also planning to invite Professor Pan." Li Zhiming said.

"Him? Although his research in number theory is not as good as his brother's, he is indeed pretty good in the proof of Goldbach's conjecture. Are you planning to invite anyone else?" Wang Yuan asked again.

"I haven't thought about it yet." Li Mingzhi replied.

"According to what you just said, it may not be very easy for us two old fellows to finish Zhou Ming's proof of Goldbach's conjecture in a short period of time." Speaking of other people who haven't figured out yet, doesn't that mean that there are only him and Lao Pan?
One of them is 78 this year, the other is 86, one is old and the other is about to be old. It really depends on the two of them to prove whether Zhou Ming's proof process is right or wrong. It is indeed not something that can be done in a short time.

"It's okay, let it take longer. Besides, I have asked him to write the proof process as a paper and post it on the Internet, and mathematicians all over the world will soon be able to prove right or wrong. In fact, I still feel Zhou Ming's There is nothing wrong with the proof process." Li Mingzhi defended himself.

"Okay, okay, I think I'll rush over and have a look tomorrow." Wang Yuan was itching to be told by Li Mingzhi at this time, and wanted to rush to Luzhou early to take a look at Zhou Ming's proof of Goldbach's conjecture.
