"Let's call it distribution deconstruction. ”

Chen Zhou glanced at Yang Yiyi with some surprise: "You have been looking at me?"

Yang Yiyi smiled and nodded slightly.

"Hmm......" Chen Zhou pondered slightly, and then said with a strange expression, "Do you really want to call it D-D method?"

Yang Yiyi didn't react for a while, but soon she understood what Chen Zhou meant.

"Hey, don't call it D-D method, how can distributed deconstruction sound like distributed structure method?"

Seeing Yang Yiyi's disgusted face, Chen Zhou laughed happily instead.

Because Yang Yiyi didn't quite get to his point.

But after thinking about it, someone uses his method to study number theory, and every day you dd it, he dd it, it's also quite fun.

"Then listen to you, it's called distributive deconstruction. ”

Chen Zhou picked up the pen and wrote the name taken by Yang Yiyi under the line of text.

For such a moment, this kind of girlfriend can understand her feelings, which makes Chen Zhou very happy.

"Hee-hee, that's good, you do the research, I'll take the name. Yang Yiyi looked at Chen Zhou from the side and said playfully.

Chen Zhou looked at Yang Yiyi with a doting face, didn't hold back, reached out and rubbed the girl's head.

After a pause, Chen Zhou asked softly, "Yiyi, since you have been watching it for so long, do you have any ideas?"

Yang Yiyi tilted her head and thought about it, and said softly: "The words of prime numbers, from the perspective of multiplication, are equivalent to the 'atoms' that constitute integers. In terms of the study of this 'atom', there have always been two major methods, which are the sieve method and the circle method that you studied at the beginning. ”

"Hmm. Chen Zhou nodded lightly in agreement.

Yang Yiyi glanced at Chen Zhou and continued: "But prime numbers themselves are 'random', and when researching, it is difficult to go directly to the end from these two methods. ”

"Hmm......" Speaking of this, Yang Yiyi pondered for a while, she was thinking about how to express herself.

Chen Zhou didn't rush her, and patiently waited for Yang Yiyi's words.

In fact, whether it is the sieve method or the circle method, what they have in common is that the prime equation is first converted into an integer equation, and then the entire prime number problem is studied. ”

"However, your current distribution deconstruction method is like adding a new transfer station in the middle, building a consistent distribution, or a random distribution formula. ”

"Consistent distribution can be regarded as 0-order randomness, and in the same way, we can further study and define 1-, 2-, and k-order randomness. ”

"I guess it's a new field of research. ”

After Yang Yiyi finished speaking, he looked at Chen Zhou, but Chen Zhou fell into thought.

Yang Yiyi's words are very simple, and they are indeed the result of Chen Zhou's doing.

However, Chen Zhou felt as if he had grabbed one thing less.

As Yang Yiyi said, the classic idea of prime number research is to first convert the prime equation into an integer equation.

The integer equation is then solved.

That is, the solution set is found on the set of positive integers.

The idea is very simple, almost equal to the entry-level questions of the high school Olympiad.

It's just that, considering the difficulty of studying prime numbers themselves, it's not an entry level.

But that's also where the approach comes in.

Solve the unknown.

This is the basic idea of mathematical research.

The distribution deconstruction method that Chen Zhou thinks about is to add a step.

There are more steps, and the overall difficulty has not changed.

Naturally, the difficulty of each step changes.

Just, is that really the case?

Seeing that Chen Zhou never spoke, Yang Yiyi was afraid that he would make a mistake in his thinking because of his own words, so he whispered: "Happy, I actually can't understand many of the methods you research, such as consistent distribution and random distribution, or I only figured it out by looking at the information while reading, you don't have to take it too seriously." ”

Chen Zhou still didn't react, he fell into the circle of self-thinking.

"What is that point?"

Chen Zhou kept asking himself in his mind.

Yang Yiyi is really a little worried, can she still make people stunned?

She thought carefully about what she had just said, and did not think that there was anything wrong.

"Did I just say something wrong? That transit station is actually just how I feel. Don't ......," Yang Yiyi said cautiously.

Chen Zhou suddenly raised his head, looked at Yang Yiyi, and asked urgently, "What did you just say?"

Yang Yiyi was stunned for a moment, and said hesitantly: "Transfer station?"

"Yes, the transfer station ......," Chen Zhou kept repeating.

Immediately, Chen Zhou's eyes lit up: "I understand, the difficulty is not an average score of ...... on each level."

"What do you mean?" Yang Yiyi was a little confused.

Chen Zhou smiled lightly at Yang Yiyi, reached out and rubbed Yang Yiyi's head vigorously: "Yiyi, thank you, you are really amazing!"

After speaking, Chen Zhou's eyes became clear, and the thoughts in his mind had been opened.

Take out a pen and paper and write quickly.

Yang Yiyi felt inexplicable for a while.

But seeing Chen Zhou like this now, she also relieved herself.

"It seems that Happy did fall into a daze just now, and this will be broken, hum!"

Yang Yiyi, who was thinking like this, pouted unconsciously.

Her attention couldn't help but turn to the scratch paper in front of Chen Zhou.

On the scratch paper, Chen Zhou wrote:

【...... When a prime equation is converted to an integer equation, the solution set of the integer equation is not transformed into all positive integer sets, but into a positive integer subset with positive density......]

At this moment, Chen Zhou's thinking was clear, and his hand holding the pen was also extremely stable.

At this moment, he entered a wonderful state.

After these days of hard work, he finally got what he wanted.

Originally, he thought he had completely figured out the method of distribution deconstruction.

But after Yang Yiyi's unintentional words, he suddenly figured out the real core idea of the distribution deconstruction method.

Breakthroughs in thinking, plus technological improvements.

This is Chen Zhou's opportunity now.

Of course, he is still at the stage of an ideological breakthrough.

Yang Yiyi watched it again for a while, and then stopped watching.

She is not a mathematics major, nor is she a student specializing in number theory, and she can't understand it now.

It's just that Chen Zhou's focused side face still makes her glance at it from time to time.

After all, there's no better moment than admiring a boyfriend who is focused on work.

Time passes on the tip of the pen.

Chen Zhou has always been in this wonderful state.

Outside the library, it was getting dark.

Chen Zhoucai put down the pen in his hand.

This time, the train of thought was too smooth.

So smooth that he never stopped to pick up a pen and some scratch paper.

"That's right, that's it......"

"Compared with the classical idea, all the difficulties are concentrated on the first step, and the distribution deconstruction method cleverly shares the difficulty of the first step......"

"Although the difficulty of the second step has increased, the overall sharing has reduced the difficulty of the problem itself......"

Seeing the smile on Chen Zhou's face, Yang Yiyi knew that he had got his own answer.
