"Xiao Ran, what is this doing?" Looking at the young figure who suddenly began to write content on the whiteboard with his back to everyone, a trace of doubt flashed on Kong Jiyuan's face, and he couldn't figure out what medicine Xiao Ran was buying in the gourd.

"It seems to be arguing for the Kratz conjecture." Zhao Licheng said hesitantly, as he spoke, he took out Xiao Ran's paper distributed in the No. 3 lecture hall and read it carefully, knocked on the handrail with his fingers, and said to himself:

"The process of this Kratz approximate conjecture argument is already very rigorous, it stands to reason that he only needs to follow the ideas in the paper, and this academic report is considered very successful, but he suddenly abandons the paper and argues alone, is there any point in doing so?"

"It's not certain that this academic report will end in failure."

Hearing this, Kong Jiyuan's eyes showed a trace of worry, and he forcibly made up for it: "Maybe Xiao Ran should have his reasons for doing this." ”

Zhao Licheng shook his head: "I don't know." He added: "But it's useless for us to speculate here, just look at it with peace of mind." ”

"After all, this is an academic report at the International Mathematical Union, and there are so many bigwigs here, he shouldn't joke with his future."

Several Yan University professors who came with Director Hetian were also a little unable to sit still at the moment.

"He's going to prove Kratz's conjecture in public?" An old professor with gray hair was a little uncertain, and in his personal experience, Xiao Ran's thesis was already well argued, and there should be nothing to add.

Now he put aside his paper and wrote a line of equations on the whiteboard, and he could not think of any other reason than to prove the Kratz conjecture.

"Young people just have momentum, and it's not okay to be old!" Another professor also lamented that this young man was too bold to challenge world-class mathematical conjectures at the lecture meeting.

He didn't think about the consequences, if he failed?

At this time, an old professor next to him was annoyed: "I just said that Xiao Ran is so young, he should have given a few more words of advice before coming, you see, you see!" You can go on and on, but if you have to get these moths, you will be in trouble if you make jokes."

Director Tian, who was sitting in the front row, turned his head and comforted him with a gentle expression: "Old Yang, don't be too nervous. I also understand Xiao Ran, this kid, since he dares to do this, he naturally knows it in his heart and relaxes. ”

"How can I not be nervous, this is not in the country! In foreign countries, in front of so many international scholars, we must always pay attention to some international influences, Xiao Ran is now making an academic report on it, which represents not only him personally, but also the face of our Yanda and the image of the country!

If I had known that he was so nonsense, I wouldn't have agreed to him making this academic report! The old professor named Lao Yang was dissatisfied.

Director Tian's face darkened when he heard this, Lao Yang seemed to be talking about Xiao Ran clearly, but in fact, he was secretly rubbing and accusing him of not knowing anyone, after all, he took the initiative to give up this opportunity to Xiao Ran.

At that time, Lao Yang faintly revealed his dissatisfaction, but this quota was originally Director Tian's own, and no one else could gossip about who he wanted to give it to.

In addition, although Xiao Ran is only a freshman, but his grades are hard, not everyone can publish papers in the "Annals of Mathematics", at least, although this Lao Yang has also published many SCI papers internationally, none of them can compare to the papers in the "Annals of Mathematics".

Therefore, although Director Tian announced that he would let Xiao Ran make an academic report at the International Mathematical Union instead of him, Lao Yang did not dare to publicly call Director Bantian even if he wanted to gossip.

That's it.

Unexpectedly, at this time, he still caught the opportunity to vent.

"Okay, Lao Yang Ling don't say a few words!" The gray-haired old professor couldn't stand it anymore, "You still said that you should pay attention to international influence, look at what you look like now!" The noisy one makes foreigners cough! International friends look at jokes, that's how you pay attention to international influence? ”

"That's it, Lao Yang, you too, your temper is about to change, no matter whether Xiao Ran is confident or arrogant, when you go back and close the door, whether it's praise or criticism, we don't have anything to say, we can't let people see jokes outside!"

The older generation of scholars still have a very strong sense of honor for the collective, and the so-called family ugliness cannot be publicized, not to mention, whether Xiao Ran is really "family ugly" is not certain, Lao Yang jumped out at this time to openly fight, which naturally caused public anger.

Seeing that he had become the target of the public, Lao Yang snorted and gradually fell silent.

The whispers of the people below naturally did not affect Xiao Ran at this moment, and he had completely forgotten where he was when he was completely in the state.

His hands danced swiftly across the board, and mathematical symbols and equations quickly took shape under his pen.

Time seemed to become irrelevant in this moment, he was completely immersed in the world of mathematics, his mind jumping, connecting all kinds of seemingly unrelated concepts and ideas.

[Let any function f:N=1→R be any natural function lim(N→∞)f(N)=+∞.]

【Syrac(Z/3Z)=2^(-a1)+32＾(-a1-a2)++3＾(n-1)2＾(-a1a)mod3＾m】

Soon, a whole whiteboard was filled with dense calculations, and this time, without waiting for Xiao Ran to speak, the staff on the side handed another whiteboard with interest.

Xiao Ran's hand paused slightly, and he continued to write on the new whiteboard.

Professor Walls' sharp gaze stared at the whiteboard, and he suddenly opened his mouth and asked his old friend next to him, "Do you think he can succeed?" ”

Director Tian, who had been staring at the equation on the whiteboard and didn't move his eyes, smiled and said softly, "I have confidence in him." ”

"Huh." Professor Walls smiled and quipped, "Saying this kind of thing is not like the character of you Chinese. ”

Director Tian said happily: "Are you interested in making a bet, just bet on whether Xiao Ran can successfully prove the Kratz conjecture?" ”

Professor Walls raised his eyebrows when he heard this, and finally moved his gaze away from the whiteboard to Xiao Ran, looking at the young back who was struggling to write, he pursed his lips, and finally did not speak.

The first row of guests in Lecture Hall 3 was also discussing this issue.

Professor Richard Cruz of Oxford sits on the right-hand side of the first row, and to his left is Peter Schulz, last year's Fields Medal winner!

Professor Cruz, who was staring at the whiteboard and holding the pen tightly, finished reading Xiao Ran's first whiteboard, turned his head and asked Peter Schultz who used a notebook to verify Xiao Ran's calculations.

"What do you think, Mr. Schultz?"

Peter Schultz stared at the whiteboard he was writing, his eyes didn't move, he just nodded lightly and said: "At present, the first version of the equation has not found any omissions, and it is also an interesting idea to solve the Kratz conjecture with partial differential equations.

However, since the birth of the Kratz conjecture, it is not uncommon for no one to think of using a differential partial equation, but they have all encountered the same problem.

That is, they usually only expect to establish "temporal local" results that control the evolution of time, and the evolution of these temporal n Col(N) is only as large as the small multiple clogN number.

However, to have Col(N) all the way down to f(N) a result that requires more like almost "global time", in which evolution is controlled for a long time, so much so that the orbit almost reaches a bounded state N=O(1)"

"If he can't find a way to solve this problem, then the whole argument process can't be talked about."

Hearing this, Professor Cruz looked at the first whiteboard again, and said thoughtfully, "So do you think he can find this way?" ”

Peter Schultz gave a noncommittal smile: "Who knows? ”

Peter Schultz, as last year's Fields Medal winner, is the top math master of the new generation, and this level of genius is naturally the most authoritative figure when it comes to academic conferences and involves mathematical content.

Peter Schultz's assessment was told to others by those who were nearby.

Soon, the whole venue knew.

Kong Jiyuan and the others naturally knew Peter Schultz's evaluation, and looked at Xiao Ran on the podium with complicated expressions for a while, not knowing what they were thinking.

Minutes and seconds passed.

Soon, there were still a few minutes left in the originally set time for the 45-point academic report, but Xiao Ran still didn't stop, and as a staff member who maintained order and controlled the process, he was ready to routinely come forward to remind him.

However, before he could come forward to remind him, he was stopped by a member of the International Mathematical Joint Committee.

This is a memorable moment for the genius who dared to challenge the world's mathematical conjectures in public in his academic presentations, whether he succeeded in proving the Kratz conjecture or not.

Naturally, the people of the committee did not hesitate to adjust the flow of the meeting for him, genius, and it was normal to be a little lenient.

What's more, they also want to know if this twenty-year-old boy is really confident, or arrogant.

Will it be a big joke or witness a great moment?

They're looking forward to it, too.

On the stage, the fourth whiteboard was already full, and looking at the fifth whiteboard dragged by the staff, Xiao Ran slowly exhaled the turbidity in his chest.

Facing the four whiteboards that had already been written, the corners of his mouth curled.

"The big picture is decided!"

Facing the brand-new whiteboard, he raised his right hand again and slowly but surely wrote down the next line of calculations.

【……】

【……】

[Therefore, starting from any positive integer, after a finite iteration of the function C, the natural number 1 will eventually be obtained]

As the last line of the equation was written, Xiao took two steps back and finally looked at the five whiteboards lined up in front of him.

Then he turned his back to the perfect answer sheet he had handed in, and faced the audience under the podium with bated breath.

He said softly: "Delay everyone a little, my proof is over!" ”

The momentum in the lecture hall was condensed, and the hustle and bustle was gone, leaving only the dead silence that could be heard by falling pins!
