In an activity room of the Princeton University Library.

Push open the door and rush in. Vera pours on the table with a happy face. She purrs for a long time with her mouth open, and finally says a complete sentence.

"He is studying the Riemann conjecture!"

Sitting at her desk, Molina did not look up at all, because even if she did not look up, she could imagine what a "narcissistic" expression was on this guy's face at the moment.

"The paper on arXiv? I already know. What's so fussy about... "

It's better to say that because of this, the sense of urgency in Molina's heart has become more and more intense.

The problem that was stared at by that man has never been missed. Even the problem of NS equation and young mills equation, which are the same level of Millennium problem, fell in front of him.

Even because he became the academic leader, he has rarely appeared in the mathematics field in recent years, and has never participated in any academic conferences, big or small, but the mathematics field has never forgotten the legend about him.

Even today, there are still myths about him on Princeton campus.

There is no doubt that land boat is a strong opponent.

She has been fighting for this conjecture for several years. If she gets the first prize in the end, she is not sure whether she will collapse

"Molina..."

Looking at Willa strangely, Molina blinked in a little indeterminate way, "what's the matter?"

Vera smiled shyly and asked, "what do you think he has studied?"

Looking at the two red clouds floating on the white cheek, Molina said with a headache, "how can I know? Why don't you just ask him? I remember you had his mailbox. "

"I......" Some coyly played with her index finger. Vera, blushing, dodged Molina's eyes and looked at the Ivy hanging on the edge of the window I don't deserve him now. "

No way!

Ah ah, I can't stand it!

With her hands on the table, Molina stood up, put her hands around Vera's shoulders, stared at her dodging eyes and said earnestly.

"Listen, my dear miss puyoi. Although I know that he is your idol or even your ideal lover, you must know that he is our opponent now! It's our enemy! You can't do it -- "

maurina said half of it, and Vera didn't hesitate to interrupt.

"I will not be his enemy!"

In the eyes of the elk, the rare one was firmly dispelled.

“…… Well, I'll put it another way, "with her palm on her forehead, Molina pondered for a long time, and finally her eyes brightened and she snapped her fingers and said," didn't you have an agreement with him about the fields prize? "

“!”

On hearing this, Vera's expression immediately became tense.

Sharp capture of this moment, Molina's mouth raised a smile, patted the little girl's shoulder and continued.

"Come on, if we solve Riemann's conjecture, let alone the fields prize, we'll have more than enough to win fields's medal 10 times."

Holding her breath, Vera clenched her fist and murmured to herself.

"If I solve the Riemann conjecture He will notice me. "

Giving the little girl a look of encouragement, Molina said in a positive tone: "yes, it's not just him, the whole world will notice you."

Vera's face was even redder. She looked down at her toes and smiled shyly.

"The whole world, even the whole world..."

"He alone is enough."

……

For the mathematical world, which is relatively short of gossip, the famous figures such as Lu Zhou began to study Riemann's conjecture, which is not trivial news. From mathover flow to Princeton University campus, the news that Professor Lu is studying Riemann's conjecture has almost become the most popular topic nowadays.

Not only are students keen to talk, but professors are no exception.

Such a big event, of course, could not escape the ears of Professor feverman, the head of the Department of mathematics.

Almost at the same time that Vera was surprised to tell Molina the news, Professor feverman also came to Professor deline's office with the printed version of the paper.

When he arrived at the office, deline was sitting at his desk, calculating something on the rough paper.

Noticing the footsteps at the door, the old man with bright forehead raised his eyelids slightly, looked at the stack of papers in Professor feffman's hand, then took back his eyes and said with no ups and downs.

"I guess you have that preprint that guy's hanging on arXiv in your hand."

"It seems that you have seen it," Professor feverman said with a helpless expression, throwing aside the paper he just printed. "I didn't expect that your news is so well-informed.""Anyway, I will accept some new things, at least the Internet, which I used 20 years ago..." Pushing the glasses on the bridge of his nose, Professor deline moved his eyes away from the scratchpad on the desk. "That's why you came to me?"

"What is it?" Professor feverman made an incredible expression and joked in a funny way, "haven't you heard of that legend? If anyone proves Riemann's conjecture, he will be immortal not only in the abstract sense, but also in the practical sense. "

The legend comes from a long time ago. At the end of the 19th century, Hadamard, a French mathematician, and Poussin, a Belgian mathematician, made the first substantial progress since the Riemann conjecture was put forward more than 30 years ago. Then they lived to 98 and 96 years old respectively.

It's amazing that we can live to be nearly 100 years old in that era when medical conditions are not rich. So there is also a saying that has been around for a long time, that is, who can prove Riemann's conjecture, who can be immortal in the physical sense.

Of course, it's just a joke, and it's been teased for nearly a century.

Hearing the old joke, deline snorted twice, glanced at the corner of his mouth and said.

“…… This is the old man hundreds of years ago, and it is still believed. Bohr and Landa, who have proved Bohr Landau theorem, contribute much more than Hadamard. If I remember correctly, two people died in their sixties. "

"Well, it seems that God doesn't care for everyone," continued professor feverman, with a gentle smile and a shrug of his shoulder. "Don't you think his paper is very interesting without these strange legends?"

Professor deline: "I refuse to comment until the formal proof paper comes out."

Professor feffman smiled and said, "I don't want to ask you if you like him. I'm just curious about the point he mentioned in his paper that we should start with π (x) function to solve Riemannian zeta function. I tried to follow his thinking, but I didn't find any interesting clues I'm curious. How do you think he will solve this problem? "

Professor feverman: "what do you think he will do?"

Professor deline glanced at him. "You and he have worked together on the NS equation. Don't you know him yet?"

Professor feverman made a helpless expression: "in fact, I know little about him. He is used to being alone in life and work."

After hearing this, Professor deline pondered for a moment.

Maybe he was lost in memories. After five minutes, he said slowly.

"Riemann conjecture is not the kind of problem that can be solved by finding the direction. In fact, I can say at least ten research ideas that may solve this problem, but so far, no one research idea really gives me hope. π (x) function is a relatively new idea, but it can only be said to be 90% new. You know, no one has tried it before. "

Professor feverman nodded.

It's not the first time he's heard someone try this direction, even in the coffee shop downstairs, and he's shared similar ideas.

"He is a scholar who is good at using tools, but also a scholar who is good at creating tools. Whether he can get something out of π (x) function or not, I am sure he can find a suitable tool for us to solve this problem. "

Professor feffman: "group construction method?"

"Not necessarily," said Professor deline, with a rare smile on his face, "it's a puzzle that has puzzled the mathematical world for a century and a half. Maybe he will tailor a new method for it, which will help us better understand and use Riemannian zeta function."

After a pause, he continued.

"Next year's International Congress of mathematicians looks forward to it."

Professor feverman shrugged and said, "he doesn't have to come."

Deline shook his head.

"Believe me, he will come."
