Chapter 833 The Poincare Conjecture Has Been Proven

Chapter 833 Poincaré Conjecture...has been proved

It is easy to say that it is completely open, but it also requires methods and ways.

Although Chang Haonan and Perelman's proof of the Poincaré conjecture is simple and easy to understand compared to the method proposed by the latter in the previous life, it still requires a certain amount of topological knowledge to understand.

At least 99.99% of the people on the earth are definitely not expected.

Moreover, the length of the compiled text is at least dozens of pages.

Considering that Chang Haonan also used some numerical calculation methods in the final solution process, an appendix should be added to supplement and explain the calculation program.

The final complete version must be more than 100 pages.

Therefore, traditional media such as radio, television, newspapers, etc., are definitely not expected.

Can you imagine the scene of a female news anchor reading a mathematical paper from beginning to end with a smile on her face?

Haonan can't do it.

So we still have to rely on the Internet.

And if we mention completely open academic websites...

There is no doubt.

arXiv.

Although this was originally a website for researchers in the computer field, by 2000, its content had gradually included other disciplines such as physics, mathematics, and biology, and it had also gained considerable recognition in the academic community.

Of course, in addition to arXiv, the same document will be uploaded to the official websites of Beijing University of Aeronautics and Astronautics and the Steklov Institute of Mathematics at a later time.

When Chang Haonan sent this proposal to Perelman by email, he soon received a reply from the other party.

Different from the usual conciseness.

This time, perhaps because he finally realized his long-cherished wish, or perhaps because of the joy of meeting a soulmate, in short, Perelman's reply this time was not only long, but also rarely carried a bit of excitement between the lines.

[In fact, it is also my wish to publish the results through arXiv instead of a mathematical journal directly, but considering that this historic result was completed by the two of us, I decided to fully respect your opinion...]

[I am very happy to see that you made the same decision as me, which shows that we are similar not only in academic level but also in academic pursuit. For me, this joy is no less than solving the Poincare theorem itself...]

This email once again confirmed Chang Haonan's previous thoughts-

Perelman is not a loner, but he rarely meets people who can communicate with him on an equal footing in terms of ideas.

"Then... prepare to submit..."

Chang Haonan closed the email page and began to organize the contents on the draft paper into the computer bit by bit...

Three days.

Another three days.

Chang Haonan finally completed the last check and uploaded the .pdf format document to the website.

Compared with many magazine submission websites that require copying and pasting content to the web page, arXiv can directly upload files, which is quite friendly.

Then...

Click Submit!

arXiv does not have a peer review process, so the uploaded documents will be seen by researchers who are interested in related fields at the first time.

"Ha——"

After doing all this, Chang Haonan yawned.

Fortunately, when the computing center was built before, a temporary dormitory was specially set up on the same floor as the computer room.

Otherwise, I might have to sleep on the floor during this period.

But even so, I couldn't sleep well when I was worried.

In this case, I worked non-stop for more than half a month.

Even he felt the fatigue like a tide when he relaxed.

Before leaving the computer room, Chang Haonan refreshed the webpage for the last time.

It was found that the number of readings had exceeded 100 in less than a minute.

Obviously, although the corresponding European and American time is either morning or midnight, such a heavy paper will obviously not lack attention...

...

Chang Haonan, who came out of the computer room, was originally going to contact Zhu Yadan directly and ask the latter to take him home.

As a result, he met Tang Lintian, who came to his door for the countless times, in the corridor.

"Chang... Professor Chang?"

Liu Chenchen was repeating to Tang Lintian what Chang Haonan had said before his "retreat", that no one should disturb him.

He was only halfway through his words when he saw Chang Haonan coming out of the work area on the other side.

"Professor Chang what..."

Tang Lintian, who was standing opposite him, actually just came over after lunch and didn't have much hope.

For a moment, he didn't even react to what Liu Chenchen was saying.

But he soon noticed that the other person's eyes were focused on behind him.

So he turned his head sharply.

Then his pupils shrank:

"Professor Chang, I finally saw you..."

Tang Lintian strode forward and walked in front of Chang Haonan:

"You have been out of touch for more than half a month. What if something urgent happens..."

Before he finished speaking, Chang Haonan waved his hand tiredly:

"If someone calls the red phone in my office, Teacher Liu will notify me."

"Since the phone didn't ring, it means the sky won't fall..."

After speaking, Chang Haonan turned his head and looked at Tang Lintian next to him:

"Principal Tang came to see me this time..."

"Oh..."

Tang Lintian was stunned for a moment, then replied with a smile:

"It was last week that I saw in the newspaper that some mathematical institute in the United States was offering a reward of US$1 million for seven unsolvable mathematical problems. I wanted to come over and ask you, you and Perelman The professor was trying to solve the Poincaré conjecture whether it might be inside, but he didn't see you several times in a row."

"Later on, I almost developed a habit of taking time to come over every day to see if you come out... but I even forgot to take the newspaper..."

There is a legend that if you do something for 21 consecutive days, you can form a habit.

Then Tang Lintian is indeed getting closer now...

At this time, Liu Chenchen also intervened:

"I still have that newspaper, if necessary..."

"Need not."

Chang Haonan shook his head gently:

"The computer room also has computers that can connect to the Internet. I'm just in seclusion, not cutting off contact with the outside world."

"I know the seven major mathematical problems of the millennium."

In fact, apart from contacting Perelman during this period, he was basically in a closed state.

It was only when Tang Lintian mentioned it that he remembered such a thing.

But it’s too troublesome to explain, so I’ll just say I saw it online.

"Then Poincaré's conjecture..."

"If nothing else, it should be inside."

Chang Haonan's tone was quite determined.

Tang Lintian, on the other hand, was immediately dazzled——

The Millennium Mathematical Puzzle, with its $1 million reward, has indeed had a considerable impact.

One day's news broadcast even reported the matter in three sentences in a briefing session.

If before the heat completely subsides, a professor from Beijing Hang University solves one of the problems...

Thinking of this, he immediately asked:

"Then... after you solve this problem, will it be... the first one..."

Tang Lintian pointed at Chang Haonan and then outside, his words already a bit incoherent.

Just thinking about that scene made the corners of his mouth curl up involuntarily.

If there weren't two people in front of me, I would probably have to perform a dance.

However, what Tang Lintian never expected was...

"No need to wait any longer..."

Chang Haonan covered his mouth and yawned:

"We have solved it..."

His tone was so flat, as if he was saying, "I ate two fried dough sticks and drank a bowl of soy milk this morning."

So much so that Tang Lintian didn't even react at the first moment.

"ah?"

"Solved... what?"

But in an instant, he realized the answer to his question.

"etc……"

Tang Lintian was shocked:

"You mean... Poincaré..."

He had been working very hard to restrain himself just now.

Now that Chang Haonan was so frightened, his hands and feet didn't obey his orders at all.

"Yes... the paper has been posted to arXiv without going through any journal, so it can be read now."

Chang Haonan glanced at Tang Lintian who was startled and trembling all over with sleepy eyes:

"Let me rest for two days, then I will send you the manuscript of the paper and put it on our college's website..."

After saying that, regardless of Tang Lintian, who was speechless and unable to make any movements, he staggered towards the door...

After a long time, Tang Lin finally came back to his senses.

"Secretary Liu, do you still remember that Millennium Mathematics Conference...when is it?"

"May 24th."

Liu Chenchen replied almost without thinking.

She had known before that her boss was solving a mathematical problem. Although as a liberal arts student she didn't know what it was, she still paid close attention to the relevant news.

"So...what's the date today?"

After asking this question, both of them turned their heads and looked at the electronic perpetual calendar hanging at the end of the corridor.

May 24, 2000…
