Regarding the Zone conjecture,

Xu Mang already had a general idea last night, but because he was holding Xiao Man at that time... didn't put his ideas into action, and now with Xiaoman's support, Xu Mang felt that he could give it a try, besides... A Ferrari can also be awarded.

"Oops!"

"Your expression is a bit excessive!" Yang Xiaoman looked at Xu Mang's tormented look, and instantly became annoyed, and said angrily: "I'm your wife... Don't you know what your habits are? also put on the appearance that he was at a loss. ”

"Hey, hey..."

"My dear good wife!" Xu Mang smiled and hugged Xiao Man in his arms, and said gently: "You are so beautiful!"

"Cut!"

"Isn't this nonsense?" Yang Xiaoman glanced at him, didn't care about the eyes of other tourists, shrunk into Xu Mang's arms, and said greasy and crookedly: "Of course I'm beautiful, otherwise how could I be arched by your big pig's trotters." ”

meanwhile

Many tourists noticed Xu Mang and Yang Xiaoman, and at the same time, everyone's face was full of shock, the world is getting crazier and crazier, the girl looks like she is seventeen or eighteen years old, and the boy is... Unexpectedly.... What the hell did he think?

The day's play ended quickly, Xu Mang and Xiao Man dined in the hotel's restaurant, all of which were just some home-cooked dishes, but Xiao Man had a poor appetite because she saw some people's comments during the day, and she was still scrolling through Weibo at the moment.

"Husband?"

"How do you refute them?" Yang Xiaoman asked seriously: "I'm really angry... I'm very puzzled, I checked the background of these well-known big Vs, good guys... Almost all of us are Chinese, all of them are foreign nationals, and as a result, we make Chinese money here, and we have to scold Chinese people, what does it mean?"

"Oops..."

"It's normal. Xu Mang ate the black pepper beef tenderloin, and said indifferently: "What do you do with them?"

“...”

"Husband... You are suddenly so Buddhist!" Yang Xiaoman was stunned for a moment, and said in surprise: "Aren't you angry at all? It's been blown up a long time ago, why don't you blow it up now? Are you really being smoothed out by society?"

Xu Mang shrugged his shoulders and said with a wry smile: "It's just that I've encountered too many and I'm used to it... Now there are still people on the Internet who scold me every day, these people can't see the rise of China, as long as there is any wind and grass, they are very happy. ”

"Humph!"

"I'm very upset!" Yang Xiaoman said angrily, "Don't let me find them, otherwise... Let them go bankrupt!"

soon

The husband and wife finished dinner, and then went to their room, Xu Mang used the hotel's paper and pen, sitting at the table in a daze, while Xiao Man was still the same as usual, sitting on the bed and desperately swiping his mobile phone, basically watching Douyin, laughing like a female blind stream.

suddenly

Xu Mang's mobile phone rang, and there was a pleasant ringtone.

"In that distant time and space, it is the mysterious ancient legend, after a long time, it still remains in my heart!"

Yang Xiaoman: ???

Belch?

This... Isn't this a cartoon from my childhood?

"Hello?"

"Huh?" Xu Mang said with a confused expression: "My child was kidnapped by you?"

Words fall,

Xu Mang glanced back at Xiao Man, showed a confused expression for a while, and asked cautiously, "Wife... Our child has been kidnapped, what should we do now? The other party asks for a ransom of 1 million, or... Call the police!"

Yang Xiaoman: (* ̄〈 ̄)

This idiot,

Received a liar's words, and look at him.

It didn't take long for

The other party called Xu Mang's Alipay for two hundred yuan, and then Xu Mang hung up the phone, and the whole process shocked Xiao Man, this... What the hell is going on? With such an IQ coming out to be a liar? In a few words, the other party is fooled and lame.

Also

This big pig's trotter is not a good person!

Yang Xiaoman remembered the past, especially in high school... Although her husband has now changed his ways, he still has the word 'bad guy' engraved in his bones.

In a few seconds,

Xu Mang received a text message from a scammer, and the content was very simple... It says, you're a liar!

"Husband?"

"Is this ringtone of yours the theme song of "Legend of the Fengshen List"?" Yang Xiaoman asked curiously: "Don't say it... I've watched a few episodes... I don't know why I watched it, maybe I was attracted to the theme song. ”

"Hmm..."Xu Mang nodded and said indifferently: "I think... Technical conditions are never the key factor that restricts domestic animation, take our childhood as an example, the production conditions of this animation are very simple, but it still makes people's blood boil after watching. ”

Words fall,

Xu Mang smiled: "When I was a child, because of this cartoon, I fought with others every day. ”

“...”

"Big idiot!" Yang Xiaoman couldn't understand the behavior of fighting every day because he watched the animation and then imitated the picture inside... I didn't expect my husband to be a member of this group.

As night falls,

Xu Mang finally put away his heart and began to break this level seriously, in fact, this problem seems very simple, but in fact, it will be difficult when you start, first you need to use discrete geometry, then there must be no problem.

Discrete geometry, on the other hand, focuses on the combined properties of points, lines, circles, polygons, and other geometric objects, such as how many balls of the same size can be placed around a sphere, or how to arrange circles of the same size in the most dense way on a plane.

Or how to place the maximum number of balls in space...

Xu found that the zone problem of the Zone conjecture was closely related to some other problems in discrete geometry, one of which was the so-called plank problem, which involved covering the disk with bands of parallel lines.

At this point,

I suddenly realized that in fact, this zone conjecture is a nesting doll-style problem, which needs to be constantly pushed back... And so on to find that original question.

"Husband?"

Yang Xiaoman wore pajamas, walked to the side with a twist, found a chair and sat down, and said with a smile: "Can you let me participate in it? Don't you forget... Lady, I am the first place in the International Mathematics Competition!"

Not to mention,

Xu Mang's heart was moved... Because there are too many layers of nesting dolls in this problem, I have to solve them one by one, which is really a bit too busy, if there is one more helper, it is almost twice the result with half the effort, and Xiaoman is the best candidate.

"I'm a little tired..."Xu Mang frowned, and said seriously: "You go and rest, don't exhaust yourself." ”

"No way!"

"I must participate!" Yang Xiaoman said seriously: "Anyway, the old lady will stay here and not leave." ”

“...”

"Well... You can help me solve the plank problem. "It is better to prove in a concise way that the width of the strip used to cover the surface of the circle is at least equal to the diameter of the circle, that is to say, there is no better way to cover the disc than with a plank with a width equal to the diameter of the circle." ”

Yang Xiaoman: (# ̄~ ̄#)

Bastard!

How can I solve such a professional math problem!

"Goodbye!"

Words fall,

Xiao Man returned to his big bed.

"Huh?"

"This is leaving?" Xu Mang looked back at his wife and asked with a blank expression, "Aren't you helping me?"

"Get out!"

...

Princeton

Professor Smith was going about his day-to-day business as usual, and as an expert in astrophysics, he had no interest in the current Zone conjecture competitions at various universities around the world.

Bang bang bang,

There was a knock at the door, and it was an old man about the same as Professor Smith.

"John King?"

"Why are you here?" Smith asked curiously, seeing his old colleague, "I think... You must be guessing for Zone, right?"

"Hmm!"

"Smith... We may be in trouble. John King smiled wryly, "This damn Frenchman... The Zone conjecture solved is very difficult, and I heard that the process will be announced to the world in two months... Damn it... Our mathematics department at Princeton may be disgraced. ”

“...”

"And what are you going to do?" Smith asked.

"I want to ask you to help contact Xu Mang, maybe if he makes a move... to save our Princeton math department. John King said, "I remember... He is an emeritus professor in the Department of Physics and is part of Princeton. ”

"Looking for him?"

"I'm afraid it's not a small price!" Smith said seriously, "and it could cost the math department a lot." ”

Price?

Even if the price is great, it can only be considered!

John King smiled bitterly: "It doesn't matter..."

Smith was silent for a long time, then raised his head and said, "John King... Xu Mang has been on vacation recently, and he has to take a year off for about a year... Coupled with the fact that the Nobel Prize is about to be announced, how can his mind be on the Zone conjecture. ”

"Ugh..."

"yes!"

"Even if it is Xu Mang, it is impossible to solve the problem in two months. John King sighed: "It's better to solve it on your own." ”

Words fall,

Straight out of the office.

For now,

The world has been stumped by the Zone conjecture, but there are a few universities that are more objective in their progress, and despite Princeton's claims of difficulty, they are actually the fastest, followed by New York University, Stanford University, Oxford University and MIT.

The duel between the geniuses of all walks of life has attracted the attention of many people, and there is competition between them, but they have the same goal, that is, to defeat France.

But

Many media found that one-third of the geniuses of the mathematics departments of these five top universities are of Chinese descent, and most of them have settled abroad directly after studying abroad, and at the same time have obtained foreign residence status.

Followed by

These foreign media began to operate routinely, exaggerating foreign excellent theories in various ways, and some well-known domestic Vs also responded to the call and created a lot of negative emotions.

And all this,

Xu Mang saw it in his eyes, and he quietly observed in secret.
