Chapter 5 Definition of the paper

The selection of research topics is not blind, but requires careful consideration.

On the one hand, Cheng Nuo needs to choose goals based on his own abilities. Currently, only mathematics is specialized in, and other subjects are just more predictive than ordinary people. There is still a way to go before publishing a paper alone.

The papers that can be published can be limited to the subject of mathematics for the time being.

On the other hand, you should not ignore anything in order to become famous. You should specifically select major topics that are very practical and can significantly promote technological progress to publish.

Because doing so is to invest in the enemy.

Just imagine, with the current industrial foundation that can be ignored in the Republic of China, if any high-tech is developed, it will not have the ability to take root at all. Instead, it will have a high chance of being used by foreigners to innovate the technology and then dump it into the domestic market, thereby squeezing the living space of the Chinese people.

Yours is mine, mine is mine.

In the end, maybe it could be taken away by the Japanese, and the situation would be even worse. At that time, our protagonist might have become a sinner for the ages.

Good technology can only be left for yourself.

As for the future development of local industries, we naturally go to the village quietly first and don’t want to shoot.

So the topic selection conditions for the paper are now very clear, that is: it is mainly mathematics, famous but not very practical, and it is best to be about the one that does not have it.

Then it will be easy.

After moving the luggage on the table, Cheng Nuo took out a piece of manuscript paper and spread it on the table, picked up a pencil and started writing and drawing.

First of all, the domain theory. As a field in algebraic number theory, it was initially written by the German mathematician Hilbert in 1898 and conjectures the relationship between the group of the art domain and its Abel expansion. Therefore, he proposed the famous "Hilbert Domain Theory" at that time and put forward four conjectures.

Hilbert's student Furtwengler was very talented and was the first to prove the first three before 1907.

Unfortunately, the goddess of mathematics quickly abandoned him, and there was no progress for 23 years since then, until 1930, when the poor Austrian mathematician proved the fourth conjecture.

In recent years, the Japanese Sadao Takagi published an article "Theory on the Relative Abel Domain" in 1920, solving a famous problem in the theory of segmented domains in algebraic number theory, "Cronek's Dream of Youth", proving the existence of general category domains, and directly creating the category domain theory.

"It seems very tempting to be the founder of a discipline."

Cheng Nuo stopped writing, circled the three words "domain theory" on the manuscript paper, pinched his chin and thought carefully

And from another perspective, creating a discipline is of great significance, and it is far more than just a personal reputation.

As the founder of modern mathematics in Japan, Takagi Sadari introduced algebraic number theory, which was still in its early stages of development, to Japan, helping the island country to cultivate the first batch of modern mathematics talents.

Under this influence, he successively emerged from the world-renowned mathematicians such as Masashi Nakayama, Kurahiko Kohei, Kuroo Sato and others, and successfully built algebraic number theory as the direction of their country's mathematics.

Then, from point to surface, from surface to body, gradually expanded from core fields to other disciplines, and later went to the forefront of world mathematics.

Although I don’t want to admit it, before Cheng Nuo traveled through time, Japanese mathematics was basically on par with the Russians in the world rankings, and even surpassed some overall, second only to the United States and France.

Looking back at our country, the beginning of algebraic number theory has to be counted from the introduction of Mr. Hua Luogeng in the 1960s. Among them, the gap between the two countries is half a century, and it is necessary to train several generations of mathematicians, so many mathematical nouns used now are also introduced from Japan.

Therefore, whether it is for the country, the people, or the ones, it is strategic to introduce algebraic number theory in China.

It's settled, it's it.

What is called "Cronek's Dream of Youth"? It is better to change it to "Dream of Domestic Mathematics Development".

As for the Goldbach conjecture? Let’s talk about it slowly first.

After all, it was not until Cheng Nuo was electrocuted and died, with the help of computer Peruvian mathematician Harold Heoffgate, he solved the weak Goldbach conjecture.

The Qiang Goldbach conjecture still remains on Chen Jingrun's research, and the progress has been almost zero in the past few decades.

But this is also good. If you have time in the future, you will write a progress in the journal every once in a while, and it will perfectly agree with the topic selection conditions.

After Cheng Nuo determined his goal, he cleaned the manuscripts written on the table with rubber, and then fired a match into ashes before he could finish it.

Although there are only some small inspirations recorded on the paper, it is still a bit shocking when it is put at the moment. It is a bit risky to not erase the traces.

After doing all this, Cheng Nuo felt relaxed and didn't even need to prepare for the project report. He took a deep breath, took out the new manuscript paper and started writing a big book:

"Suppose k is the algebraic number domain, m is an integer factor in k, m is the formal product

Therefore, we can call it a generalized ideal group.”

I couldn't stop the inspiration when I came, so I wrote this paper in one breath.

All that is left is some text polishing and format adjustments, which are not problems.

I stopped writing and saw that it was already evening.

Sure enough, when you are immersed in something, time will pass very quickly, unlike the three minutes before lunch at school, which passes slowly than three hours.

I touched my stomach and was just hungry, so I might as well have a meal first.

Cheng Nuo packed the manuscript paper, walked to the door and took back his coat from the clothes hanger and put it on. He locked the door and prepared to go out and find a stall to have a clean and hygienic meal.

Of course, except for bean juice.

The environment of this inn is pretty good, but unfortunately the room rate does not include food, and the price of ordering separately is a bit expensive.

Now that the work has not been determined, the source of the company cannot be increased, so I have to save money.

Is it better to spend one yuan less on the money on it or save some money.

After a day of snow, you can basically walk on the streets clearly, so you don’t have to worry about surprise waiting for him.

Unexpectedly, as soon as I walked to the door, I ran into an acquaintance head-on.

"Sir, this is not a coincidence. I met you as soon as I came."

When he looked up, he saw that this was not Li Lao San. Cheng Nuo also quickly said hello: "It's a coincidence. Master, have you eaten? It's cold outside, so hurry up and sit in the house."

Li Laosan waved his hand and signaled that he would not be ready to go over. He pointed to his bulging clothes and said that he was a little cramped: "I have eaten at home. Didn't you tell you to send the fried triangles in the afternoon? I'll send them to you with grease paper just after it was released. You can't mind it."

"But it's cold outside. I'm afraid it will get cold, so I put it in my arms and eat it while it's hot."

How could He De let others treat him like this?

Cheng Nuo was moved by this. After taking the oil paper bag, he felt it was really hot, and even felt it was a bit hot.

Seeing that Li Laosan was leaving, he refused to let him leave no matter what he said.

"Old Li, eat more and eat more, and leave when your body is warm."

Li Laosan Buyi: "Sir, I really have eaten it, I can't eat it anymore."

"Master, what's wrong with eating two more bowls of rice? Besides, you're doing physical work, that's not bad."

He directly pulled Li Laosan to the inn lobby and found a table to sit down.

"Old Li, there's nothing to be aware of, right?"

"Sir, you really don't need to do this. I'm full at home, just order your food." Li Laosan was still making the final resistance and refused to invite him to dinner.

But some money cannot be saved. If you treat me sincerely, I will sincerely reply to you.

Cheng Nuo shook his head: "Old Li, I will just treat you as if you are not jealous. I will be unhappy after a while and I will not regret buying medicine."

After saying that, he followed suit and imitated the locals and shouted to the clerk: "Master, let's make a fuss!"

"Sesame paste, pickled leek flowers, sauce and tofu are all available."

"And your signature dish."

"Okay!"
