Lu Shanmin has long been familiar with what a function is. Give it a rule f to get another cluster B. This is the function.

But today Ye Zixuan told him that if you draw a line at will, it is a function.

Lu Shanmin couldn't figure it out. The lines he drew casually were inconsistent with no rules at all. He couldn't find a rule at all. How could it be a function? Ye Zixuan's jumping thinking made him unable to keep up with the rhythm at all.

Looking at Lu Shanmin who was helpless, Ye Zixuan held her cheek with one hand and looked at him with a smile.

Lu Shanmin looks pretty good when he thinks seriously, and it looks very similar to his father when he works hard.

His nose bridge is very high, like a bulging hill; his eyes are bright, like stars in the sky; his lips are slightly thicker, with white teeth and fresh inside; his skin is slightly darker; his facial features are clear, very similar to a popular male star on TV.

Ye Zixuan could see it and thought to herself that she was quite handsome.

Lu Shanmin thought about it for a long time but couldn't understand this problem.

"Can functions without laws be called functions?"

Ye Zixuan grunted and said, "Then you can call it a function without any problem."

"There is a view in the mathematics community that there are laws in this world, from dust to the universe, that can be described in mathematics. I believe this view."

"The so-called inability to rule is actually just that we humans have not discovered that law. Ramanujan is a man with super intuitive sense. His extremely complex formulas have not been directly derived through any calculations, because he keenly captured it

Rules that ordinary people cannot capture”.

As he said that, he pointed to a random line drawn on the paper, "This line cannot be expressed by a specific function, just because we have not found its laws, and it does not mean that there is no laws."

Lu Shanmin nodded thoughtfully, thought for a moment and asked, "Is such a function meaningful?"

"The classicism and intuitiveism in the mathematics community have been arguing about this issue. Now, these weird functions are called generalized functions, but the definition of generalized functions has been debated endlessly, and there is no unified definition."

"Everything in this world is composed of laws, and understanding and exploring these laws is of course meaningful. Generalized function theory is also called distribution theory. If you find the corresponding laws, you can solve many random variable problems, such as economic theory, which involves

If it can be simulated, it can avoid economic crises in advance and is conducive to economic regulation. For example, physical quantities such as mass, point charge, dipole, instantaneous impact force, instantaneous source, etc. are not only convenient to describe, but also physical meanings.

It's clearer, too."

Lu Shanmin heard it, and had a little understanding, but was still more confused.

Ye Zixuan raised her head and said proudly: "I am studying this issue now. If I can make a certain breakthrough, hehe, I can become the first female mathematician to win the "Fields Medal".

On the east side of Baihui Park, more than a dozen ferocious people stood on the lawn.

Masen is also well-known in Parkway District, but it is much worse than the gangsters of the same period. Many of the people who worked together more than ten years ago have become bosses, and some have opened bars.

Some of them started their business and became the bosses he called them.

Only he is still relying on collecting some protection fees. However, in recent years, with the improvement of the legal system and the improvement of people's legal awareness, it is difficult to even receive protection fees. I remember that when Changzan was not yet Tongzhigang Avenue,

There were many flowers blooming on Zhigang Avenue. At that time, we watched the venues for three or four bars, and we had to call each other when we went in and out.

Later, Chang Zan unified Zhigang Avenue and incorporated some people, but most of them were driven out, and he was one of them. However, Chang Zan was not only someone, but also his mother was rich, so he could only bury his resentment in his heart.

.

The only income now is to take on some private work, beat people for others, and smash things, which can be considered the lowest level among the lower nines.

In the past two days, the intermediary introduced a big business. I don’t know which rich man this person offended, so he bought his hand for 300,000 yuan. As long as he was not killed, someone would come forward to pay for the medicine if he was disabled.

He was arrested and sent to jail for one year to give him 100,000 yuan.

Masen didn't have the heart to sympathize with the man, only knowing that this was a big pie that fell from the sky. He was not afraid of something. He just asked two brothers to go to prison for two years, and a hundred thousand yuan a year, without mobilizing him.

Someone rushed to go to prison.

A small man trotted to him from a distance.

"Brother Ma, I saw it clearly. There was only the boy and a woman in the pavilion, and there was no one in the visible range around me."

Ma Sen showed a hideous smile, "Everyone cheered me up. The middleman said that the boy knew martial arts. He would greet me hard for a while except for his head. I'm the most fair in dealing with people. Who will do the most ruthless in a while?

Leave him the opportunity to eat in prison."

The dozen people behind him suddenly seemed to have been injected with chicken blood. For them, this is a huge good thing. Most of these people have been in the bureau. How to judge the fight and how long to go for prison?

The judge also knew that if someone was injured, he would only be sentenced to one or two years in prison if he was injured.

They easily cost 100,000 yuan a year, and they all turned red. They wanted to go to this prison immediately. Several people even made up their minds to destroy the man for a while and then did not run away, waiting for the police to arrest him.

On a tall building outside the park, Meng Haojun put down his telescope and showed a cold smile on his lips.

"Why haven't you done it yet?"

Next to Meng Haojun was a short and fat man who was only about 1.6 meters tall.

The fat man smiled, "Young Master Meng is not in a hurry. This guy has a bodyguard in the park. It should be a thrust idea to see his head, but he should not have undergone special bodyguard training. He is not aware enough. He has been in the park.

I was wandering around, and now I was very close to that person and was turning to the west of the park. When he turned to the west corner, he was the farthest from the pavilion, and when he was taking action, he was more stable."

Meng Haojun smiled coldly, "You are quite professional"!

The fat man bowed his hand, his face squeezed into a pile, and said with a smile: "We are eating this bowl of rice. Meng Da is rare and knowledgeable and has rich connections. He will introduce me more to the business if he has the opportunity in the future."

"Let's talk about it when you do this. This person knows Sanda. Are you good at all?"

"Hehe, don't worry, Mr. Meng, this person named Masen is a famous ruthless man in Baihui District. He is full of a group of desperate people, so there is absolutely no problem."

Lu Shanmin was pondering about the generalized function that Ye Zixuan said, and a slight and messy footsteps disrupted his thoughts.

The hunter's ears were extremely sensitive, and Lu Shanmin frowned and suddenly stood up.

Ye Zixuan looked at Lu Shanmin strangely. Seeing that he looked cautious and showed fierce eyes, he was so scared that his heart skipped a beat.

"What’s wrong with you"?

Lu Shanmin left a light sentence, "Waiting for me here, you are not allowed to go anywhere," saying that he ran out of the pavilion.

Lu Shanmin thought that most of these people were coming for him. Instead of sitting in the pavilion and waiting for death, it would be better to take the initiative to avoid Ye Zixuan being timid and suffering from his fatigue when she was present.

He ran towards the sound of footsteps, turned a row of trees, and saw more than a dozen ferocious men running towards this side.

These people also saw him, and immediately their eyes shone with golden light, as if they saw him glittering gold.

Masen shouted, ‘Come it for me’.

More than a dozen people instantly pulled out the steel pipe from their waists and rushed towards Lu Shanmin.

Ten meters apart, Lu Shanmin exerted his force at his feet, increasing his speed to the fastest, like an angry bull, instantly rushing into the crowd.

"Boom", the first person hit by Lu Shanmin's shoulder flew backwards, and the two or three people behind him were knocked down directly.

Ma Sen was shocked, but he was stunned for a moment, then waved the steel pipe and smashed it at Lu Shanmin.

"Bang bang bang", the unarmed Lu Shanmin was instantly hit several times in the back and arm.

Lu Shanmin raised his foot and kicked someone out.

Then he rushed forward suddenly and wanted to continue running eastward. This place was very close to the pavilion. He didn't want the war to affect Ye Zixuan.

However, as soon as he took two steps forward, he was forced back by two machetes coming towards him.

Although these people have no foundation in martial arts, they obviously often fight in groups, and the group cooperates very well, surrounding Lu Shanmin in the center.

Lu Shanmin tried his best to avoid the two machetes and vital parts, and let the rest be hit by the steel pipes.

He punched the man in the face next to him with a straight punch, and directly knocked the opponent down. Then he hit a steel pipe with his arm, and knocked down a person with a heavy punch.

In the midst of breath, Lu Shanmin had already brought down five or six people. He thought that these mobs would be shocked by his momentum, but he did not expect that these people had no intention of retreating. They all looked excited, just like the Japanese devils saw the flower girl.

He walked forward desperately, and even among the people who were just knocked down, two of them stood up and continued to rush over with gritted teeth.

Lu Shanmin was secretly frightened. This was a group of desperate outlaws. But he was not worried. Now he is no longer the Lu Shanmin on Minsheng West Road, and he doesn't care about these dozen people.

Two steel pipes came towards him, and Lu Shanmin snorted coldly, grabbed them with both hands and pulled them hard, and took them over the steel pipe.

With two steel pipes in hand, he suddenly felt like a tiger's wings. His strength was not something that these ordinary people could bear. He almost fell down with one stick.

He left room for this and did not greet the vital parts.

Although Lu Shanmin showed his might, the group of people still did not retreat at all. After being knocked down, anyone who could stand up to his feet and continue fighting with all their might.

Ma Sen became more and more anxious as he fought. He never expected that his more than a dozen people were at a disadvantage, but he never thought of giving up. He had never thought of giving up. He had more than a dozen people under him. Three hundred thousand, this was not a small number.
