Chapter 787 Make big news
In fact, the official release of the sixth issue of the Annual Journal of Mathematics in 1999 was slightly earlier than Chang Haonan expected at the end of November.
Just after the middle of the month, he received an email stating that his paper had been published and had been selected to be included on the back cover of this issue of the journal.
Along with the email, there was an invitation letter from Mikael Lagerstedt with basically the same theme as last time.
However, the content is much richer.
The other party said that the annual mathematics conference at the end of next month, because it happens to be at the junction of the millennium, is regarded as "a summary of the previous millennium and an outlook for the next millennium", so it will bring together many people from the previous era. and famous mathematicians of the era.
Naturally, they also include Richard Hamilton, Isadore Singer, Michael Atiyah, Yau Shing-Tung and other tycoons in the field of differential geometry.
Moreover, Lagerstedt also said that the annual meeting will not involve topics such as award selection and project sponsorship, but will only involve pure academic exchanges, as well as eating and drinking.
This basically implies that although the annual meeting is hosted by Princeton, it will not involve disputes over the interests of different schools of thought——
Foreign academic circles also have their own problems.
And because of their high academic level and longer history, the relationship between mountains is even more complicated than in China.
Many of the love and hatred of catching a horse can even write a book alone.
It's just that people who are below a certain level cannot even enter other people's circles, and of course they can't feel it from the outside.
Of course, in the final analysis, any mountain top is for fame and money.
Therefore, no awards or sponsorships are involved, which saves a lot of trouble.
Looking at this lengthy invitation, Chang Haonan smiled helplessly.
The other party probably thought of him as an aloof and strange person like Perelman.
I thought the reason I didn’t reply to the email last time was because I didn’t want to get involved in complicated school struggles.
It should be said that as a senior editor, my level is still high.
It's a pity that I guessed in the wrong direction completely.
He didn't go to the meeting simply because it was inconvenient for him to go abroad due to his current status, and it had nothing to do with being indifferent to fame and fortune.
If the annual meeting were held in China, he would definitely go there more actively than anyone else...
While thinking this, Chang Haonan copied the link attached to the email into the address bar of the browser——
In this era, the technology to directly identify links in text format still does not exist.
Not surprisingly, it is the reading page of the current issue of the journal.
In the first few years when the digital version of the Annual Journal of Mathematics was released, it provided free reading and downloading. Later, it was discovered that no one would buy the physical version, so it became a paid subscription.
It has to be said that as the most influential journal in the field of theoretical mathematics, it is probably not the only one. In addition to Princeton University's reputation in the field of mathematics itself, the publishing house is also really good at typesetting and proofreading.
Even the author Chang Haonan looks much more comfortable than the original manuscript he wrote in Word.
By the way, he also took a look at other articles published at the same time as himself.
"A complete set of a pair of orthogonal incomplete Latin squares..."
"The unique continuation of the wave equation on the hyperplane..."
"Mathematical study of multiphase flow under shear through order parameter formulas and asymptotic analysis..."
"..."
It must be admitted that China does still have a long way to go in terms of theoretical science.
Apart from Chang Haonan, there is no other author from China.
Even if there are some Chinese names among them, if you look at the institutions, they are from the United States or Europe.
However, as far as the content of this issue of the journal is concerned, there are not many highlights except Chang Haonan's article.
On the one hand, it is impossible to have so many earth-shattering results. Even in the world's top journals, many articles in them are inevitably suspected of being filled with water.
On the other hand, as the last issue in 1999, almost half of the space was reserved for review-type articles signed by various big names.
It can be regarded as fitting the slogan of the banquet next month, "Looking to the Next Millennium."
One of them even mentions his results.
The author is none other than Richard Hamilton…
Considering that the two were actually published at the same time, it is obvious that the other party is also one of the reviewers...
Chang Haonan shook his head, closed the web page, and then looked at the newspaper he had kept next to him these days.
Nancheng Daily.
The reason why he told Tang Lintian to stand still before was because he was waiting for this opportunity.
Now, the time has clearly come.
At this moment, a notification tone suddenly sounded on his email interface.
A new email.
Judging from the website address, it should be from Yenching University.
"Tazuna?"
Chang Haonan was stunned for a moment, and then remembered that he and the other party had met once at the dinner after the National Day.
It is a one-sided relationship in the physical sense.
They only exchanged a few words in total, and they were not even considered acquaintances.
In the text, Tian Gang first congratulated Chang Haonan for his article being published in the Annual Journal of Mathematics, and said that his "Chang's Lemma", or "Millennium Lemma" can be ranked as the most popular in the field of differential geometry in the past five years. An important achievement, and if you look at the domestic perspective, it can be regarded as the most important achievement in the entire field of mathematics since the 5s...
A rainbow fart wrote two long paragraphs, and then got to the point. He said that Yenching University has plans to establish a mathematics research center, and is currently inviting world-renowned scholars in the field of mathematics to give lectures. He hopes that Chang Haonan can accept the invitation and go. Give a lecture on the field of differential geometry.
Chang Haonan was not surprised by this kind of invitation.
In particular, the other party mentioned "Chang's Lemma" in the email, which shows that this title has gained certain recognition at least within the international mathematics community.
It has been a long time since such representative results appeared in China's local mathematics community.
Considering that the author is not from mathematics or even science, this article is undoubtedly equivalent to a bombshell.
However, just a few hours after the paper was published, I could finish reading the article, write such a long email, and send it to him on the same day...
The possibility is really slim.
Therefore, Chang Haonan guessed that Tian Gang was probably one of the reviewers, and these things had been prepared long ago.
Just waiting for this day.
This can also explain why the other party wanted to talk to him rather bluntly during the National Day dinner.
However, Chang Haonan was still prepared to decline the invitation in the email.
If the Mathematics Center of Yenching University continues to develop according to the original timeline, it will involve a series of useless gossip.
No need to get involved.
After thinking for a moment, he also responded to an email.
First, he praised the other party according to the terms published by Google, and then said that he was not a professional mathematician and had projects to do. The paper was just some "accidental discoveries" during the research process, so there was really nothing to do in a short time. I have my energy to take care of other things, but I promise that I will take the stage to introduce my research results at the "appropriate time"...
Then, click Send.
……
At the same time, the office of the president of Beijing Hang University.
Tang Lintian answered a call from the Chinese Academy of Sciences.
"Principal Tang, congratulations, you have a great talent!"
Yuan Xiangya's voice rang on the other side of the phone:
"It took less than half a year to produce such a big result without any fanfare. It makes those of us who specialize in mathematics a little embarrassed."
It was a round of flattery that immediately confused Tang Lintian.
He raised his head slightly and spent a few seconds recalling it. He was very sure that he had not heard of any earth-shattering achievements in the school recently.
"Professor Yuan, what are you talking about?"
Tang Lintian asked somewhat puzzledly.
The two are obviously not on the same channel.
"Principal Tang, you don't have to hide me from me, right?"
Yuan Xiangya said in a half-joking tone:
"During his doctoral defense, wasn't I still a member of the review committee?"
"Is it...Chang Haonan, Professor Chang?"
he asked tentatively.
Until then, Tang Lincai vaguely guessed that the other party should be talking about Chang Haonan.
After all, the latter promised him just last week that there would be big results in the near future.
However, I didn't expect that this "recent" would be so close.
"Who else could it be?"
At this point, Yuan Xiangya probably realized that Tang Lintian seemed to really not know the situation, so he explained:
"A paper by Professor Chang was published in the just-released December 1999 Annual Journal of Mathematics, and in a review in the same issue, the leader of differential geometry, Professor Richard Hamilton, also directly used "Chang's lemma" was used to name the two conjectures he proved."
"Old Tang, although you are not a person in the field of mathematics, you should be able to think of the significance of a result named directly after him..."
After hearing this, Tang Lintian's hand holding the receiver trembled slightly and he opened his mouth, but no words came out for a long time.
Chang's Lemma...
You know, Yuan Xiangya also has "Yuan's Lemma" named after him.
The latter was able to become a "half-step academician", that is, a second-level professor, at the age of 39, precisely because of this achievement.
Chang Haonan's first step into the world of mathematics actually reached this level...
