Chapter 187 He Really Proved
Sandston was in a good mood today. He was walking on the road to the Department of Mathematics at Cambridge University with a faint smile on his face on his way to the classroom to give a lecture. He would respond to students' greetings when he met them on the way.

Yesterday, he publicly spoke out through his own account to question the news that the Goldbach conjecture had been solved.

It has received support from many people and has caused quite a stir.

Ever since his authority in the mathematics community dropped drastically due to the Yau Cheng-Tung conjecture incident, he has hardly ever shown up in the academic world.

Even when faced with invitations to academic exchange activities, he chose to refuse.

Now that I have finally taken this opportunity to re-establish my mathematical authority, I am certainly in a good mood.

In addition, Xu Yuan and the so-called Journal of Mathematics have not made any response to this matter so far, which makes him more convinced of his judgment that the Goldbach conjecture has not been completely solved.

His class today was for undergraduate students in the Department of Mathematics, and when he arrived, the spacious lecture hall was already full of people.

Judging from the appearance, there are at least a hundred people.

The students also have different skin colors, and there are international students from other countries.

I have to say that he is quite popular at Cambridge University.

There are quite a few students who sign up for each lecture.

At this time, he stood on the podium, put the things aside, and then taught at his own pace.

An hour passed in the blink of an eye.

After the main course content was completed, in order to adjust the classroom atmosphere, Sandston gave the initiative to the students.

Let them ask questions freely and he will explain and answer them.

As for the questions, they can be about what we just talked about, or they can be about mathematical difficulties we encounter in daily life.

It immediately aroused everyone's enthusiasm to a great extent.

……

"The questions raised by Meng En are very good. You should try to exercise your thinking in the process of learning mathematics."

"Who else wants to ask questions?"

Sandston stood on the stage and answered questions from several white students. Then he looked at the audience again and asked the students to ask questions on their own initiative as before.

As the words fell, there was a pause of a few seconds, and then a yellow-skinned boy sitting in the back row raised his hand.

"What's the problem with this student?" Sanston looked at the other person and asked.

The boy did not delay at all. He stood up immediately after hearing the words and asked the question in English with a serious face.

"Hello, Professor Thornston."

"I saw your speech on the interactive mathematics community. Do you think the Goldbach conjecture has not been proved?"

Li Ming is an international student studying mathematics at Cambridge. Although he has been abroad for several years, he has always been paying attention to the domestic mathematics community. Especially after witnessing Xu Yuan, the pride of the domestic mathematics community, he directly regarded him as a mathematics idol in his heart.

I hope that one day I can achieve academic results in the field of mathematics like Xu Yuan.

Glory to the country.

Help the domestic mathematics community rise.

Therefore, when he saw the news online and learned that Xu Yuan had actually solved the ultimate problem in number theory and proved the Goldbach conjecture, he naturally felt very proud.

Especially, this paper was published in the domestic journal Acta Mathematica Sinica.

This made him even more emotional.

Whether you are studying in China or abroad, the first choice for publishing papers is naturally overseas mathematics journals.

Although he really hoped that his paper could be published in his own mathematics journal, even the most popular mathematics journal was not ranked internationally in terms of authority.

The mere fact that major universities do not recognize it cuts off the possibility of submitting the paper to domestic journals.

But now Xu Yuan has broken this perception and published a paper of this level, proving the Goldbach conjecture, directly in the Journal of Mathematics.

I thought that the Journal of Mathematics would have the opportunity to increase its international influence and even become a journal recognized by the international mathematics community.

Naturally, I was very excited.

Maybe there will be a chance in the future to submit my paper to the Journal of Mathematics with dignity.

But even in this happy situation, I suddenly saw Professor Sandston publicly questioning the proof process of Goldbach's conjecture on the interactive community frequently used by mathematicians.

It is said that Xu Yuan published his paper in an unknown journal, which showed that he was not confident in his paper.

This shows that the Goldbach conjecture has not been proved.

In addition, there are many mathematicians who blindly follow the trend, which makes him very angry.

Overseas mathematicians and scholars may not understand why a paper of this level should be published in an unknown journal with an impact factor of only a few tenths.

This casts doubt on the authenticity of the news that the Goldbach conjecture was proven.

But he understood very well, knowing that Xu Yuan, as the most talented mathematician in the history of China, had the ideal of making the domestic mathematics community rise.

The most important factor in determining the level of a country's mathematics community is the authority of its mathematical journals.

Now Xu Yuan has used his paper to take the Journal of Mathematics to its first step, which shows his good intentions.

It is no exaggeration to say that this incident made him admire Xu Yuan even more.

It even feels like a fanatical fan.

In this situation, how could a fan remain unmoved when seeing someone questioning their idol?

How could he face his idol after graduation? He couldn't get over it. So he specially signed up for Sandston's class today and raised his hand during the free question session.

On the podium, Sandston frowned slightly, looking at the tall boy with short hair below the stage, with a hint of displeasure on his face.

However, the students in the classroom are all mathematics students, so naturally they often ask or answer questions in the interactive community.

The proof of the solution to the Goldbach conjecture is a question that the entire mathematics community is discussing, and everyone is certainly paying close attention to the follow-up.

And that is exactly what is happening.

Almost as soon as Li Ming finished speaking, he instantly attracted the attention of everyone present.

They all cast curious glances at him.

He also looked at Sandston on the stage from time to time, obviously looking forward to Sandston's answer.

Faced with this situation, Sanston had to suppress his emotions and then expressed his views to Li Ming again.

"There has been no new progress in the Goldbach conjecture for more than half a century since Chen Jingrun proved 1+2."

"Although Xu Yuan is very talented in mathematics, it is impossible for him to completely solve this conjecture in such a short time, so I think there is a problem with the news that the Goldbach conjecture has been proved."

“Perhaps Xu, as a Gauss Prize winner, could not accept his failure on the Goldbach conjecture, so he chose to publish an incomplete proof paper in an unknown journal.”

"Of course this is just my personal opinion. The exact situation still needs to be determined by the International Mathematical Union."

He spoke out the language he had organized in his mind, and did not forget to add a special sentence at the end.

When other students in the classroom heard this, some of them couldn't help but nod in agreement.

I also feel that it is impossible to prove the Goldbach conjecture in just one year.

Li Ming was still standing in his seat, and there was a laptop in use on the step desk.

After listening to everything that Sandston said, he did not show any anger or outrage.

His face remained calm the entire time.

The next second he continued to ask in English: "I want to know who is better in number theory, Professor Sandston or Viscount Deligne?"

Sandston frowned even more tightly: "Of course it is Viscount Deligne."

"Then why did Viscount Deligne publish an article saying that Professor Xu Yuan successfully solved the Goldbach conjecture?"

"And Viscount Deligne has publicly stated that Professor Xu Yuan's achievements in number theory have surpassed his." Li Ming took over the conversation and said decisively.

While Sandston was lecturing just now, he was checking the news on the Internet on his laptop.

I just happened to see Viscount Deligne publicly announced that he had completed the proof of the Goldbach conjecture and verified that the conclusion was valid.

Not long after the news was released, it has attracted a lot of media follow-up reports.

When Sandston heard this, his expression suddenly changed. Obviously, he didn't expect Deligne to be eliminated so soon.

The key is to stand up for Xu Yuan.

He even took the initiative to admit that he was not as good as Xu Yuan in the field of number theory.

In the past, Deligne actively verified Xu Yuan's papers, which he believed should have something to do with the publication in the Annals of Mathematics.

This time Xu Yuan gave up the Annals of Mathematics, so logically Deligne shouldn't take it too seriously.

But when faced with this news, he was severely slapped in the face. It turned out that Deligne had been paying attention to Xu Yuan's thesis from the beginning to the end.

It has nothing to do with whether it is published in a journal or the journal in which it is published.

"When did this happen?"

Li Ming looked at the change in Sangston's expression and replied calmly, "Just over ten minutes ago."

At this time, the students in the classroom immediately caused a commotion when they heard the news.

They were no strangers to Viscount Deligne. As a professor at the Institute for Advanced Study at Princeton and a grand slam winner of prestigious awards in mathematics, he had a high authority in number theory.

Now it has been publicly stated that the Goldbach conjecture has really been solved, which has caused everyone to discuss it in a low voice.

"Could it be that Xu Yuan, the genius mathematician from China, has really completely solved the Goldbach conjecture?"

"With Viscount Deligne's confirmation, it should be true."

"It's incredible that someone in the world could prove the Goldbach conjecture in such a short time."

"Why don't we have young math geniuses like this?"

"I didn't expect that Professor Sandston would once again make a very wrong judgment in mathematics."

……

As Sandston listened to the ongoing discussions in the classroom, his face darkened completely.

I still couldn't accept it in my heart that Xu Yuan could actually prove the Goldbach conjecture so quickly.

And it happened that at this time, Li Ming also took out his trump card and once again announced a piece of news that surprised the mathematics community.

"I forgot to tell you, Professor Sandston. The Clay Mathematics Institute just issued an official announcement congratulating Xu Yuan for proving the Goldbach conjecture."

Before he could even finish his speech, Thornston on the stage began to lose his focus.
