Black Technology Incubation System

"Student is here," Gu Xingyi just walked into the box, and the senior graduate student sitting on the chair greeted him with a smile, and then he looked at Lou Jianyue, "Teacher, we have ordered the dishes, take a look Where can I add a little more."

"Well," Lou Jianyue glanced at the menu, nodded, and pulled Gu Xingyi to sit beside him, "You did a good job."

The always cheerful senior smiled happily, pouring drinks for several people happily, and urging the waiter to serve food.

After a while, the waiter brought the dishes to the table.

The stew pot is a large flat iron pot, densely packed with a bunch of vegetables, there are meat and vegetables, and a bowl of rice is also given.

Gu Xing took a sip and found that the sauce used in this stew pot was very delicious, salty and delicious, and he couldn't help picking up chopsticks after chopsticks.

When Lou Jianyue saw this, he naturally smiled and brought him vegetables, but they were not all his favorites, but a combination of meat and vegetables, which was in line with his usual philosophy of health preservation.

Meanwhile, he didn't eat much himself, but chatted with graduate students about his latest project.

Gu Xingyi listened for a while, and found that what they were discussing was the problem of twin prime numbers.

The problem is this: There are infinitely many prime numbers p such that p+2 is prime.A pair of prime numbers (p, p+2) is called a twin prime.That is to say, 3 is a prime number and 5 is also a prime number. We get a prime number pair (3, 5), and the same prime number pair also includes (5, 7), (11, 13) and so on.The wait is endless.

There are many international studies on this issue.After all, the oldest and most exciting problems in mathematical number theory are related to the simplest and most mysterious addition, such as twin prime numbers, such as Goldbach's conjecture.

In this case, the strong twin prime conjecture and the weak twin prime conjecture appear.The former not only proposes that there are infinitely many pairs of twin prime numbers, but also gives its asymptotic distribution form, while the latter shows that for all natural numbers k, there are infinitely many pairs of prime numbers (p,p+2k). When k is equal to 1, it is the twin prime conjecture, and when k is equal to other natural numbers, it is called the weak twin prime conjecture.

Of course, if it's just proof to this point, it's still unattainable for Brother Lou, a research monk who looks flexible but not smart.So, in fact, his latest assignment is to advance Zhang Yitang's argument.

On the premise of not relying on unproved inferences, Zhang Yitang discovered that there are infinitely many pairs of prime numbers whose difference is less than 7000 million, thus benefiting countless math dogs who are looking for thesis topics to graduate on the road to the important problem of twin prime number conjecture.Numerous math dogs stepped forward to advance this constant step by step to 40, and then to 246, a little bit closer to the final result.

And the new fighter on this road—the research monk senior, began to challenge 46.

Although there has been no progress recently.

Fortunately, Brother Lou had some thoughts on this, after a few words, the senior nodded, ran to the front desk to borrow a pen and paper, and started to write with his head down.

From Gu Xingyi's perspective, all he could see was a big fluffy head.

Probably this is Xueba.Not learning, is on the way to learn.

With emotion in his heart, he turned his head and asked Brother Lou: "Brother Lou, are you guys challenging twin primes recently?"

"I have some ideas," Lou Jianyue nodded, pointing his chopsticks at the research monk who was working hard, "The main reason is that he is more suitable for this proposition."

"Well," Gu Xingyi frowned, thinking about the number theory knowledge base published by Training Space, and said, "Twin prime numbers are not easy to handle. Generally speaking, the most commonly used sieve method has been proven impossible to solve this problem. Proof. The results obtained by using the method over the years are not small, but I think the method seems to be a bit meaningless."

"I, I feel the same way." The other senior graduate student who had been eating in silence finally finished his meal, before he had time to wipe his mouth, he quickly raised his hand and said.He still couldn't change his shy nature, he stuttered when he spoke, and the roots of his ears were completely red, but his tone of speech was very firm.

He continued to add: "I have seen related research over the years, and the round method may only be able to achieve estimated results. If the difference in the middle is infinitely pushed to zero, it will..."

The more he spoke, the more coherent he was, gradually his ears stopped being red, and he even forgot the shyness before, wishing he could cross Lou Jianyue and get closer to Gu Xingyi.

"Well, I also have some ideas." Lou Jianyue pushed the student back on the chair, turned to Gu Xingyi and said, "You said that if we use the weft circle method like this..."

"I think it's feasible." Gu Xingyi had a flash of inspiration, and suddenly took a piece of paper from the senior who was writing a thesis beside him, and scratched the mark with the key to explain it to them.

When the hard-working research monk looked up and was about to proudly declare that he could solve a big problem, what he saw was a pot of cold dishes, a table with scattered waste paper, and three plush men who gathered together to discuss fleece head.

what are you guys saying?Why can't I understand.

Sure enough, Xueshen was either pretending to be coercive, or on the way to being coercive.

Before he had time to sigh, another female voice sounded beside him: "Hi, guest, can you pay the bill? You have stayed in the box for four hours, and the store is about to close."

The waitress still had a standard eight-toothed smile, but the poor research monk still felt a murderous aura.

With a dry laugh, he took out his mobile phone to pay the bill, and then sent the waitress away.After that, he approached the three people who were discussing like no one else, and coughed: "Mentor, students, we have to leave, it's already eleven o'clock."

The word eleven o'clock successfully brought back Gu Xingyi's thoughts, he stopped writing, and said, "Our access control is at 10:30, we can't go back now."

"It's okay." Lou Jianyue was stunned, he also forgot about this important matter, but he soon found a solution, "Go to my place tonight and stay overnight, I'll help you ask for leave."

"Okay, by the way, this question can be improved. I think it can be named the Great Circle Method." Gu Xing began to pack up stacks of draft paper.

Lou Jianyue took the draft and taught, "That's for tomorrow, you have to develop a good routine."

"Wait, what is the Great Circle Method?" The elated researcher who had just solved another problem in a thesis caught a key word. For some reason, his scalp tightened, "A new method to solve number theory?"

"To be precise, it is to solve the twin prime number problem, senior." The shy little research monk added weakly.

The big research monk petrified there: "No, you mean..."

Lou Jianyue took off his glasses, wiped off the mist on them, put them on again, and showed a gentle and sincere smile: "Dawei, your paper should be finished and sent out earlier, if it is later, after the twin prime number conjecture is proved We will have to re-select the topic."

"Why don't the seniors choose the topic again," said the little research monk who was out of the academic state, his words were still as thin as a mosquito, and his face was stained red, "I... I think I will follow the seniors to solve the questions and wait until next year. gone."

Lou Jianyue nodded helplessly.

No, are you so honest?

The great research monk who has entered the state of out-of-body state wants to cry but has no tears.

"I'm very happy to think that there are still many people like you, senior," Gu Xingyi comforted, "Which classic problem's proof didn't ruin the papers of countless people?"

"I know," the senior floated out of the hotel without touching the ground, "but it's still so sad, scientific research competition is really cruel."

"Isn't this the small building of Q University? I haven't seen you for a few months, and I feel refreshed again." A loud voice appeared behind several people. Everyone turned their heads and saw a fat man with a big belly and full of anger rolling over.

"Professor Kang," Lou Jianyue stopped, stood in front of the three of them and greeted the visitors, "It's been a long time, and you're also full of air."

"Hey, people are in good spirits on happy occasions." Professor Kang waved his hand, his face was genuinely happy, "Our University B recruited a team to sign up for this year's mathematics competition, and then I found a good seed."

He turned sideways, exposing the tall and thin young man beside him: "Xiao Xiao, say hello to them."

"Hello, Professor Lou, I have read several of your books in the field of additive number theory, and they are very well written."

Lou Jianyue smiled, although B and Q are competitive, but it does not affect their seniors' appreciation for outstanding juniors: "Have you been studying the direction of number theory recently?"

"Yes," the young man nodded, "I'm a sophomore now, and I've just learned some knowledge of advanced number theory, and I'm watching Kadoya's conjecture recently."

"It's very savvy." Lou Jianyue nodded, and politely praised, while pulling Gu Xing, who was staggering and didn't know what he was thinking, to his side.

"That's right, there are quite a few good candidates in our B major. Last year's Wei Leping was too lazy to participate in this year's competition after winning the eagle competition. We were still in a hurry, and finally found a suitable candidate." Professor Kang snorted He said, "Your Q University is very good, but the number of students these years has been declining year by year. Alas, I still say the same thing, Xiaolou, you are a young talent, why do you want to stay at Q University? Our salary is better here, and the source of students is also good.”

"The Q major is very good, and the country has always believed that the Q major and the B major are top 2, no distinction between equals." Lou Jianyue smiled, and the smile was a little colder now, "Also, our participating students this year are not bad."

"Xiao Gu, you are also confident to get a good ranking in the competition, right?"

Um?Gu Xingyi was just thinking about the application of the Great Circle, such as the miraculous effect in the Jiaogu Conjecture, when he turned his head and was called by Brother Lou.

Fortunately, the system listened and projected the conversation of several people in front of him.He quickly understood the situation based on the context, stepped forward, and showed a smile that is the second in the friendship first competition: "Hello, my name is Gu Xingyi, and I will also participate in the math competition this year."

"I've heard of you too, and you posted three SCI articles, a disciple of Mr. Gao, and the new junior uncle of the Shuimu Sect." This young man named Xiao Xiao was obviously a second-born patient. He held Gu Xingyi's hand Shaking up and down, "I will wait for you in the competition, and then I will beat you openly! The first is mine."

How should I answer?Talking harshly to each other is kind of embarrassing.Gu Xingyi wasn't used to having a second-year illness in front of his elders, so he laughed awkwardly: "Okay, I'll wait for you."

The fighting spirit in the other party's eyes burned even more fiercely. Seeing that he was going to speak harshly, Professor Kang quickly put the hot-blooded young man behind him: "Then let's watch this year's math competition."

"Definitely." Lou Jianyue promised.
