"The proof of Goldbach's conjecture is over here. I think I have proved this proposition. From now on, Goldbach's conjecture is Goldbach's theorem!" Liu Yichen wrote the last line of calculation with a faint smile on his face.

Smiling, he declared confidently.

Starting from Goldbach's letter to Euler on June 7, 1742, it spanned the 18th century, the 19th century, the 20th century, and the 21st century. It spanned four centuries and troubled the mathematics community for nearly three centuries. Countless scholars have worked hard to

, added bricks and tiles to the building, and finally he carried out the capping work.

Because of the study of Goldbach's conjecture, many achievements were born, and famous mathematicians were born.

Just when he finished his report, applause started from the first row in the lecture hall, and the applause spread from the first row to the second row... In the blink of an eye, the entire lecture hall burst into warm applause.

During the question-and-answer session, everyone's attention was mainly focused on the sieve method, circle method and group theory. The entire question-and-answer session lasted for half an hour.

"Liu, you performed very well!" Professor Deligne walked up with a smile, patted Liu Yichen on the shoulder, and then stuffed the champagne into his arms: "Take it, this victory champagne belongs to you.

!”

"This is your doctoral thesis defense. I think it will be recorded in the history of Princeton University. Next, there will be a thesis review panel composed of seven professors to independently review your thesis." Professor Deligne smiled.

Said: "But now, it is a Princeton tradition to open champagne after the report meeting. This is Princeton's congratulations to you, or you can also regard it as a kind of pressure."

To be precise, this is the tradition of Oxford and Cambridge. But Princeton is a rare Oxford-style university in the United States, so it naturally inherits this tradition.

It stands to reason that normally, after the jury reviews the paper, the paper writer will give the answer. If the answer cannot be answered, it means giving up, and it also means that the winning champagne needs to be returned.

However, Liu Yichen made an unexpected move. He opened the champagne, poured it into his mouth, and drank the bottle of champagne in one gulp.

It was not the first time for him to drink champagne, but it was the first time that he felt that this champagne was particularly delicious.

Professor Deligne looked at his disciple in astonishment, but then showed admiration, which represented Liu Yichen's absolute confidence in his own strength.

The reporters recorded this classic scene. Today they witnessed history.

"The reviewers of your paper will be Faltings, Helfgott, Ivanets, Wiles, Tao Zhexuan and seven other people. They will conduct an open, fair and independent review. Enjoy the evening banquet, starting tomorrow.

, you are busy." Professor Deligne said with a smile.

Liu Yichen smiled lightly, full of confidence. He would be the same no matter who the reviewer would be.

"Mr. Liu Yichen, I am a reporter from the New York Daily News. Will you apply for a green card in the United States? I believe that based on your achievements, the Immigration Bureau may approve your application in just one day!" Liu Yichen had just left the lecture hall when he was

The reporter focused on him, and a female reporter with blond hair, blue eyes and a super hot figure stopped him and interviewed him.

"I am from China, so I will naturally go back to China, where I have two companies and my career." Liu Yichen said with a smile: "I think if I want to immigrate, any country in the world will welcome me!"

When he first arrived at Prince University, someone from the Immigration Bureau came to him and persuaded him to immigrate, citing various benefits, but Liu Yichen remained unmoved.

"As a young super rich man, don't you think America is a paradise for rich people? As long as you are willing to spend money here, you can get anything." the reporter asked.

"I'm sorry, I think rich people can live comfortably anywhere, but I don't have high pursuit of material things. I prefer research, scratch paper, and pens, and I can live a happy life." Liu Yichen smiled lightly.

road.

"Mr. Liu Yichen, yesterday Angelina Jolie said that she admires you very much and hopes to have dinner with you. What do you think of this?" a reporter from the "Los Angeles Daily" asked.

"Sorry, I don't know much about Hollywood stars. I only know the little rock queen Avril Lavigne. I don't know the others. I'm not interested in having dinner together at all." Liu Yichen frowned, all this was nothing.

The reporter asked one question after another, most of which had nothing to do with academics. After briefly answering a few questions, Liu Yichen left.

After a short rest, at six o'clock in the evening, the banquet at the Princeton Hotel officially started.

Although it was nominally intended to provide an opportunity for scholars who had finally met each other to meet and communicate, now it seems that this banquet has completely turned into a celebration banquet held by the Institute for Advanced Study in Princeton for Liu Yichen.

There is no doubt that the proof of Goldbach's conjecture is the most important academic achievement after Perelman proved the Poincaré conjecture, and this achievement still appears in the field of number theory, which is the most difficult to produce results.

When Liu Yichen appeared in the banquet hall of the Princeton Hotel, he immediately became the focus of the audience.

Everyone knows that with Liu Yichen proving Goldbach's conjecture, there is no doubt that he will win the Fields Medal in 2014. Even if we don't talk about this Goldbach's conjecture, relying solely on Liu Yichen's previous achievements in mathematics

, no one doubts that Liu Yichen will win the Fields Medal.

Without a doubt, one hundred percent certain!

As the protagonist of the banquet, every scholar took the initiative to greet Liu Yichen and praised him. In fact, in the past three years, Liu Yichen has made outstanding achievements. Even Tao Zhexuan was not so dazzling back then.

"Everyone, everyone, please be quiet!" At this time, the music of the banquet suddenly stopped, everyone looked towards the direction of the stage, and saw the figure of Professor Deligne on the stage: "This year's academic report, the paper is

After our research and discussion on Liu Yichen's doctoral thesis, in view of Liu's achievements during his doctoral studies, he has fully proved his academic ability, so we decided to award Liu Yichen a doctorate."

As Professor Deligne finished speaking, applause erupted from the surroundings.

A doctorate in mathematics from Princeton University, definitely the most valuable doctorate in the world.

However, based on Liu Yichen's current achievements, it can be said that he can be called a doctor. There is no problem at all in calling him the strongest doctor in the world.

Liu Yichen was stunned.

He did not expect Professor Deligne to announce this at this time. He thought he would wait until the reviewers finished reviewing the manuscript and confirmed that he had proved Goldbach's conjecture before allowing him to graduate with a PhD.

"Similarly, after discussion and decision at the Institute for Advanced Study in Princeton, in view of your series of major breakthroughs in number theory and algebraic geometry, the Institute for Advanced Study in Princeton solemnly and sincerely extends an invitation to you to serve as a post at the Institute for Advanced Study in Princeton.

Researcher, continue studying mathematics." Professor Deligne said, looking at Liu Yichen with eyes full of admiration.

Everyone can't help but look at Liu Yichen with envy. The Institute for Advanced Study in Princeton is the most famous theoretical research institution in the world. It is where the top scholars in various fields conduct the purest cutting-edge research, and it does not receive any teaching tasks, scientific research funds or sponsorship.

Research organization on business stress.

In the first half of the twentieth century, after scholars such as Albert Einstein, John von Neumann, Kurt Gödel, and Robert Oppenheimer moved to the Institute for Advanced Study in Princeton, it became the world-famous Institute for Advanced Study.

academic mecca.

Let’s put it this way, since the ‘Pope of Mathematics’ Grothendieck left the world of mathematics, the world’s center of mathematics has officially moved from Europe to the Institute for Advanced Study in Princeton.

"It's really enviable. Less than two years after he came to Princeton University, he already obtained a doctorate and became a full professor. This has set a historical record! Although Tao also received a doctorate from Princeton University at the age of 21, he was 24

He was a professor at the University of California, Los Angeles when he was young!”

"It's unbelievable to think that a 21-year-old full professor has a higher IQ than Tao. Tao is the smartest person in the world."

"But for his achievements, he could actually have obtained a doctorate long ago!"

"Mathematics, that is the language of God. He must be listening to the gospel of God."

"The school is really courageous to let a 21-year-old young man serve as a full professor."

"..."

What happened at the banquet spread throughout Princeton University and the town of Princeton in less than half an hour. In such a small place, there are no secrets at all.

Liu Yichen had a good celebration with Feng Lin after the banquet. It can be said that he has graduated early.

"Do you plan to be a professor?" Feng Lin asked.

"Well, when you get your doctorate, we will go back to China together!" Liu Yichen said with a smile.

In the next time, he can study modern algebraic geometry with Professor Deligne, and at the same time study the 'standard conjecture'.

Furthermore, his grand plan has not yet been carried out. It just so happens that he has made great progress in this area and can implement this grand plan more safely.

He doesn't believe that network security measures can really be so safe.

I believe that by the time Feng Lin gets her doctorate, he will have almost completed this grand plan. When the time comes for Feng Lin to leave the United States and return to China, it can be said that no one knows.

Feng Lin was secretly moved. She knew that Liu Yichen had no plans to stay in the United States for a long time. Now that Liu Yichen had obtained a doctorate and could be hired as a professor, the reason why he stayed was to wait for her to obtain a doctorate before returning to China.

What more can a woman ask for when her husband is like this?

Liu Yichen didn't know what Feng Lin was thinking, otherwise he would definitely be secretly happy. Sure enough, speaking is also an art.
Chapter completed!
