Campus of Princeton University, New Jersey, East Coast, USA.

Braving the snow, Fan Yin wrapped his coat as tightly as possible to prevent the cold wind from getting in.

As a professor of mathematics, he also held other capacities, such as chair of the mathematics department at Princeton University, president of the faculty council, chair of the science department, acting president, editor-in-chief of the Annals of Mathematics, president of the American Mathematical Society, and a spokesman for the Princeton School.

In a nutshell, Fan Yin is the boss of the American mathematics community, and without him, Princeton and American mathematics would not be able to play.

But at this time, he also had a problem, no matter how hard they tried, their mathematical ability still could not catch up with the Europeans, especially in the face of the Göttingen school of mathematics, even more so in the dust.

Crossing the path, he came to a building with a nameplate in the editorial office of the Annals of Mathematics, pushed the door open, took off his hat and scarf and put it on a hanger, and began to shout: "Hey, boy, I heard that there is a good manuscript this time, I hope you don't let me down." ”

Wiblen, who is also a professor in the Department of Mathematics and is good at differential geometry and projective geometry, was full of excitement: "Dean, Kroneck's youthful dream has been solved, and it has been determined that the modular equation of elliptic functions with complex multiplication is similar to the Abelian expansion of imaginary quadratic fields!" ”

"Oh, God, Wiblen, do you know what you're talking about?" Fan Yin's face was full of incredulity, and he waved his hands: "Is it the conjecture that my teacher Kronek put forward?" ”

"Yes!"

Fan Yin still couldn't believe it, and while he was busy running over, he asked again: "Is it the twelfth of Hilbert's famous twenty-three questions, is Kroneck's theorem on the Abel field generalized to any algebraic rational field?" ”

"Yes, that's it!"

At this moment, Fan Yin no longer cared about the image, and directly rushed over and snatched the manuscript paper, and read it with trembling hands.

The reason why he is so excited is that, on the one hand, after receiving his Ph.D. in mathematics in Germany, Fan Yin studied with Kronecker for a long time, and the two formed a deep friendship here. It has always been a pity that Kronecke did not prove this conjecture until his death. In order to help the teacher fulfill this ideal, Fan Yin has been trying to prove it for many years, but it seems that his talent is in mathematics education, and so far he has not made any progress. Now it is possible to prove that the teacher's last wish seems to be imminent.

On the other hand, Hilbert's twenty-three questions at the beginning of the century have attracted the attention of mathematicians all over the world, and solving any of them can cause a sensation in the academic world.

What he didn't know, of course, was that the twelfth question remained unresolved in the 21st century.

In addition, Fan Yin had a more subtle personal reason, and he provided huge publicity to the magazine with this paper, which was enough to cause a sensation in the mathematical community.

In order to prevent mistakes, Fan Yin put his finger under the letter and began to read word by word: "Let k be an imaginary quadratic field, and the Hilbert class field of k can be constructed from the complex multiplication theory." The arbitrary fraction ideal a of k is the lattice of the complex region C, thus determining ......"

In order to prevent mistakes, I deliberately took out a pencil and manuscript paper, and solved the problem step by step according to the idea of the paper, but after all, I was getting older, and the sweat on my face became more and more, and finally dripped directly onto the manuscript paper.

"Wiblen, why are you burning the fireplace so hot, open the window to let in some air."

"Dean, this fireplace...... Okay, I'm going to go and open the window. "Wiblen originally wanted to say that it was your own anxious sweat, and it had nothing to do with the fireplace, but when I thought that the boss in front of me was the boss, it was better to talk a little less.

In fact, before Fan Yin came, Wiblen had already argued with other editors many times, but he didn't find any problems, and only after making sure that the conjecture was solved did he dare to show it to the boss and let him make the final decision.

As the paper was read faster and faster, Fan Yin used more and more straw paper, and finally he was directly submerged in the straw paper.

After a long time, he finally got up from the pile of straw paper with a red face, put down the pen and breathed a long sigh of relief.

Veblen hurriedly handed over a cup of coffee and asked, "Boss, what is the result, has it been proven?" ”

Fan Yin suddenly stood up suddenly, startling Veblen, who was hugged and jumped and jumped: "Verblen, Kroneck's dream of youth has been proven, do you know what it means, it means that our American mathematics is about to rise!" ”

In fact, the first job Fan Yin found after graduating from college was not mathematics, but physics. Later, he became interested in mathematics, and was introduced to Germany, the center of mathematics at that time, to study under Clay, the leader of the Göttingen School, and obtained a doctorate in mathematics in just one year.

Later, he saw the backwardness of mathematics in the United States, and was determined to build the United States into the world's mathematical center and Princeton into the cradle of the world's mathematicians.

In other words, the Western Fan is to the Princeton University Department of Mathematics, just as the Eastern Cai Yuanpei is to the Liberal Arts Department of Peking University.

"Now we can finally give those hateful Germanic people a good look." Wiblen also felt that even though Germany was in the quagmire of World War I, the goddess of mathematics seemed to be still watching over them, which was infuriating.

Fan Yin put the desk in order and said solemnly: "This paper is related to the future of our journal and American mathematics, I will give you one week, no, three days, and immediately publish it in our "Mathematical Yearbook" and publish it as soon as possible." ”

Wiblen looked embarrassed: "But we have already published one issue this month, and according to the convention, the next issue will be a month apart, so will it seem that we are not professional enough." ”

Fan Yin patted his head and said helplessly: "My dear professor of differential geometry, won't you issue a supplement?" You don't even need to bring another paper, just publish it. ”

Deliberately turned to the last page of the paper, and then said: "If you take a good look at it, not only do you prove the conjecture, but also the possibility of creating a new discipline called class field theory, don't you know what this means?" ”

Wiblen hesitated for a moment and said, "It means that this author is already ahead of everyone, and our "Mathematical Yearbook" will attract the attention of mathematicians around the world." ”

“Bingo！” Fan Yin snapped his fingers, and the future seemed to be under control: "In addition to publishing supplements, contact the author named Tom Cheng as soon as possible and give him the highest manuscript fee." ”

This Tom Cheng is an English name of Cheng Nuo, which is specially used to publish theoretical academic papers, and another English name is Jerry, which is used to publish applied papers and apply for patents in the future to prevent personal information from being found by interested parties.

"Okay Dean, I'll do it." When Wiblen had listened to the instructions, he prepared to do it.

Unexpectedly, at this time, Fan Yin stopped him again: "Slow, you wait first." ”

But as Vibron paused for further arrangement, all he responded to was the rhythmic snapping of his index knuckles on the table.

After a while, Fan Yin made up his mind and said: "I see that the author and you are both Harvard graduates, you must contact him, and say that in addition to the manuscript fee, I will hire him as a professor of mathematics on behalf of Princeton University!" ”

After Veblen left, Fan Yin, whose enthusiasm had dissipated a little, hurriedly put on his coat, shivered with cold, touched the fireplace, and complained: "Fake, which guy forgot to add firewood to the fireplace!" ”
