Chapter 833 The Poincaré Conjecture...has been proved
Full disclosure is easy to say, but it also requires attention to methods.
Chang Haonan and Perelman’s proof process for the Poincaré conjecture, although it is simpler and easier to understand than the method proposed by the latter alone in the previous life, still requires a certain topology Only by learning knowledge can we understand.
At least 99.99% of the people on earth are definitely hopeless.
Moreover, the compiled length 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 procedure.
The final complete version will definitely exceed a hundred pages.
So, traditional media such as radio, television, newspapers, etc., cannot be counted on.
Can you imagine the scene of a female news anchor reading a mathematics paper from beginning to end with a smile?
Anyway, Haonan can't.
So we still have to rely on the Internet.
And if it comes to completely open academic websites...
There is no doubt about it.
arXiv.
Although this was originally a website designed to satisfy researchers in the computer field, by 2000, its content had gradually included other disciplines such as physics, mathematics, biology, etc., and was also used in the entire academic world. It has gained quite wide recognition.
Of course, in addition to arXiv, the same document will also be uploaded to the official websites of Beihang University and the Steklov Institute of Mathematics at a later time.
When Chang Haonan sent this proposal to Perelman via email, he quickly received a reply from the other party.
Different from the usual concise and to the point.
This time, maybe it’s because he finally realized his long-cherished wish for many years, or maybe it’s because of the joy of meeting a close friend. In short, Perelman’s reply this time is not only long, but also rare in words. There was a bit of excitement.
[Actually, it is also my wish to publish the results directly through arXiv instead of a certain mathematics journal, 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 have made the same decision as me. This shows that we are not only similar in academic level, but also in academic pursuits. For me, this joy is no less than unraveling Poincaré. The theorem itself...]
This email once again confirmed Chang Haonan's previous thoughts -
Perelman is not withdrawn, but it is rare to meet someone who can be ideologically compatible with him. They are just people communicating on a peer-to-peer basis.
"Then... prepare to submit..."
Chang Haonan closed the mailbox 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 inspection and uploaded the document in .pdf format to the website.
Compared with many magazine submission websites that require you to copy and paste content onto a web page, arXiv can upload files directly, which is quite user-friendly.
Then...
Click submit!
arXiv does not have a peer review process, so uploaded documents will be seen by researchers who pay attention to related fields at the first time.
“Ha——”
After doing all this, Chang Haonan let out a long yawn.
Fortunately, when we were building the computing center, 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 can’t sleep well even if I have something on my mind.
In this case, the shaft worked for more than half a month.
Even he felt a surge of exhaustion the moment he relaxed.
Before leaving the computer room, Chang Haonan refreshed the web page one last time.
I found that in less than a minute, the reading count had exceeded 100.
Obviously, although the corresponding time in Europe and the United States is either morning or midnight, such a blockbuster paper will obviously not lack attention...
...
From the computer room Chang Haonan, who came out, was originally going to contact Zhu Yadan directly and ask the latter to take him home.
As a result, in the corridor, I met Tang Lintian, who had come to my door for countless times.
"Professor Chang...Chang?"
Liu Chenchen was repeating to Tang Lintian what Chang Haonan had said before his "retreat", as before, that no one should disturb him.
As a result, I was only halfway through my words when I saw Chang Haonan coming out of the work area on the other side.
"Professor Chang, what are you talking about..."
Tang Lintian opposite was actually just stopping by after lunch, so he didn't have much hope.
For a moment, he didn't even realize what Liu Chenchen was talking about.
But he soon noticed that the other party's eyes were focused behind him.
So he turned around suddenly.
Then his pupils shrank:
“Professor Chang, I have been waiting for you...”
Tang Lintian strode forward and walked up to Chang Haonan:
"You have been out of touch for more than half a month. What if something urgent happens..."
He hasn't waited yet. After saying that, 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, , that means the sky will not collapse..." After saying that, Chang Haonan turned to look 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:
< "Last week, I saw in the newspaper that some mathematical institute in the United States was offering a reward of US$1 million for seven difficult-to-solve mathematical problems. I wanted to come over and ask you, you and Perret. Professor Mann was trying to solve the Poincaré conjecture, maybe it was 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... I even forgot to take the newspaper..."
There is a legend that if you do one thing for 21 days in a row, you will be dead. Can form a habit.
Then Tang Lintian is indeed getting closer now...
At this time, Liu Chenchen also interjected:
"I still have that newspaper here, if you need it …”
"No need."
Chang Haonan shook his head gently:
"The computer room also has computers that can connect to the external network. I am just in seclusion, not cutting off contact with the outside world."
"I know about the seven major mathematical problems of the millennium."
In fact, except for 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.
"The Poincaré conjecture..."
"If nothing else happens, it should be inside."
Chang Haonan's tone was quite determined.
Tang Lintian, on the other hand, just stared blankly——
The Millennium Mathematical Puzzle, with a reward of US$1 million, has indeed had a considerable influence.
Even one day's Xinwen Broadcast reported the matter in three sentences in a briefing session.
What if a professor from Beijing Hang University solved one of the problems before the heat completely passed...
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, the corners of his mouth could not help but curl up.
If there weren't two people in front of me, I might 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 plain. , as if 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.
“Wait a minute...”
Tang Lintian was shocked:
"You mean...Poincaré..."
He was already trying very hard to restrain himself just now.
Now that Chang Haonan is so frightened, his hands and feet won’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 looked at it with sleepy eyes Tang Lintian was shocked and his whole body was shaking:
"Wait for me to rest for two days, and then I will send you the manuscript of the paper and hang it on our college's website..."
After finishing speaking, I didn't care that I was speechless and unable to do anything. Tang Lintian staggered towards the door...
After a long time, Tang Lintian came back to his senses.
"Secretary Liu, do you still remember when the Millennium Mathematics Conference... was held?"
"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……
