Chapter 447 Yang-Mills Existence and the Mass Gap
"Okay, that's enough to relax for today. I should get back to work."

Xu Qingshan stood in front of the floor-to-ceiling window, stretched, yawned and said.

"No way, your boss is like this, and you still want to go back to work? Is the exploitation at Jingda so serious?"

Qiu Jing slumped in the chair, shook her head, and lamented that her young boss had really good physical strength.

"It has nothing to do with the school. It's my own job."

Xu Qingshan checked his personal belongings.

"Okay, then I'm leaving."

"I always feel like you, boss, are a scumbag. You come and go as you please. You stay here for a very short time. I feel like Longjiang Base is like your little lover. You come over to meet for a while when you are free, but ignore me when you are not."

Qiu Jing curled her lips and complained.

"Sister Jing, if you are really old enough, you should find a partner. Otherwise, I always feel that you are driving all the time, which is very similar to..."

As Xu Qingshan spoke, he walked to the door. After opening it, he turned around and said something.

"A woman in the boudoir!"

After saying that, Xu Qingshan quickly closed the door and ran away without looking back.

When Qiu Jing heard this, her originally weak body straightened up, her fists hardened, and she stood up.

"You kid! Don't run! Who are you calling a resentful woman in the boudoir?"

When Xu Qingshan went downstairs, he happened to meet his uncle who was eating in the cafeteria on the second floor, and took the key to the Maybach from him.

"Uncle, where did you go this afternoon? I didn't see you at all."

Xu Qingshan felt a little surprised. He had thought that Lin Chenhua would accompany him when he ran around each work area in the afternoon.

"Oh, I've been sitting here."

Lin Chenhua smiled shyly.

"In the cafeteria all the time? Are you that hungry? Have you been eating all afternoon?"

Xu Qingshan was very surprised because there was a plate of food in front of Lin Chenhua that was obviously just eaten.

"That's not the case. I know you have to sweep the floors one by one this afternoon. It's very tiring, so I'll stay here and give you the key after you're done."

Lin Chenhua touched the back of his head and smiled innocently.

"you"

Xu Qingshan was speechless for a moment.

"Uncle, you've learned to be lazy now. Don't do it again. I'm leaving now. Come back to the city more often when you have time. Don't always stay in the dormitory here. My mother is coming."

Xu Qingshan gave instructions and left with the key.

Lin Chenhua looked at Xu Qingshan's departing back and smiled, "Hey, I'll dare to do it again next time."

Xu Qingshan drove back to Beijing University.

He did not return to the office, but went straight back to Yan Dongyuan's house.

When Xu Qingshan opened the door, the lights in the house were on.

The people in the house heard the noise outside the door and ran out to see what was going on.

"Brother? Why are you here?"

Tong Tong looked at Xu Qingshan in surprise, with some surprise in her eyes.

"Oh, have you all eaten? Why are you still in your pajamas?"

Xu Qingshan put his bag on the cabinet in the entrance hall. Tong Tongxiao walked over a few steps and helped Xu Qingshan take off his coat and hung it on the hanger.

"I haven't eaten yet. Sister Xiaoxi hasn't come back yet. I didn't go out today, so I didn't change my clothes after getting up in the morning."

Tong Tong explained as she moved a little closer and smelled the scent on Xu Qingshan's body.

"What's wrong? Does it taste weird?"

Xu Qingshan looked at Tong Tong who had a strange expression.

"I feel that my brother has a mixed smell. He must have been to a place with a lot of people this afternoon. Go take a shower and I'll get you some clothes."

Tong Tong pursed his lips and turned to go into the room.

Xu Qingshan thought about it and decided to take a shower and relax his body muscles. He had been laughing all afternoon and his face was almost stiff.

When Xu Qingshan came out of the bathroom after taking a shower, the sound of the door opening was heard again.

Jiang Huanxi, with a tired look on her face, was standing in front of the entrance cabinet in a daze.

"I'm home?"

Xu Qingshan was holding a towel and wiping his hair while greeting Jiang Huanxi.

"Yeah, I'm back."

Although Jiang Huanxi was somewhat surprised to see Xu Qingshan, her expression was still depressed and she looked lifeless.

"Why do you look so tired? Do you want to take a shower first? You haven't eaten yet? Tong Tong hasn't eaten either. Let's order some Dong Lai Shun later?"

Xu Qingshan asked curiously.

"Now I know how tiring it was for you to take the cross-level exams. I took 6 exams today."

Jiang Huanxi threw the things on the sofa and collapsed onto it.

"Forget about not eating at Donglaishun. We eat there often. Let's go to another one."

Tong Tong came out of the room and sat down on the sofa while talking to help Jiang Huanxi massage her arms to relax them.

"What do you want to eat? You guys can order it. I don't even know if there's any restaurant nearby that I can book."

Xu Qingshan sat down at the desk by the balcony.

After he sat down, he looked at his seat belatedly, then looked at the two girls sitting on the sofa and interacting with each other.

Why do I feel like something is wrong? I am clearly the male owner of this house, why do I feel like an outsider now?

"Look at Meituan Takeaway. There are already takeaway services in Beijing now."

Tong Tong raised her cell phone and waved it, looking at Xu Qingshan with a strange look.

"Brother, aren't you the largest shareholder of Meituan? You must know that Meituan has already launched a food delivery service, right?"

"How could I not know? I was just so busy that I forgot."

Xu Qingshan felt a little guilty, so he answered stubbornly.

Didn’t Lao Wang launch the takeaway service someday? It’s so fast! Why didn’t I receive any message at all? Or did I receive it but just skipped it?

"Forget it, I'll order it."

Tong Tong picked up her phone and looked at it slowly. She didn't expect this busy scientist of hers to care about the family's life.

"Then call me when it's time to eat. I'm just in a daze."

Xu Qingshan turned his chair and sat in front of the large desk, tidying up the things on his desk and thinking about where he should go next.

In fact, the various ideas and mathematical tools obtained by solving the Riemann hypothesis are a very rich treasure.

After his two papers were published in Nature and Science, within just a month, papers conducting research on Xu's conjecture began to appear in the paper database.

There are also many papers that use their own critical fiber bundles and quantum analysis to try to apply them to some stubborn problems in the past, and unexpectedly make breakthroughs. Although the mathematical field with itself as the core and source is thriving and expanding its influence at this moment.

However, there is still a lack of sufficiently important results to implement one's academic ideas.

Xu Qingshan has actually been doing research for some time, but the direction he found is not really in the field of pure mathematics.

Rather, it is a century-old problem that combines physics and mathematics.

Yang-Mills existence and the mass gap.

Originally, Xu Qingshan did not realize this. After all, his personal interest in physics was relatively less than that in mathematics.

However, when critical fiber bundles and quantum analysis were born, Xu Qingshan discovered many new concepts in both physics and mathematics that were fundamentally different from traditional research concepts.

Following this new concept further, we find that it seems to have great potential in the field of quantum physics. As mathematicians, the core problems that must be solved in response to the challenges of physicists are Yang-Mills existence and mass gap. In essence, it is a purely mathematical problem, but in order to understand and analyze it, we must start with physics.

If mathematics is the measure of the truth of the world, then physics is the truth itself.

As early as the 17th century, the physics system created by Newton could calculate the time it takes for an object to fall from a table to the ground.

But later generations soon discovered that Newtonian physics was not accurate on the extremely macroscopic astronomical scale, nor was it applicable to atomic physics.

By the early 20th century, two opposing extreme worlds had emerged in physics.

Relativity describes the universe on an astronomical scale.

Quantum theory describes the world at the microscopic scale.

Most of the time, relativity and quantum mechanics perform their respective functions without interfering with each other. General relativity is responsible for the macroscopic universe, and quantum field theory is responsible for the microscopic world.

But when a black hole appears.

The two theories will have an irreconcilable conflict. Black holes themselves are formed by the collapse of massive stars due to huge gravitational forces. Neither mathematicians nor physicists can explain what happened in the world at the moment of the stellar explosion.

Because the equations that combine relativity with quantum field theory do not make sense in their interpretation of infinity.

At the same time, when studying the nature of matter at the smallest scale in the world, the conflict between relativity and quantum theory becomes even more intense.

This means that both contain parts of an ultimate theory of matter, but neither is the ultimate theory of matter itself.

If the universe and the world really exist, then scholars must find a single, completely universal super theory that can cover everything, so that relativity and quantum theory can be approximations of this theory.

Such a theory is called the grand unified theory of matter in the physics community.

The grand unified theory of matter is essentially just a framework, but it is necessary to be able to fully explain the four basic forces currently known to humans within this framework.

Electromagnetism, gravity, strong nuclear force and weak nuclear force.

Xu Qingshan knew very well that mathematicians and physicists around the world had been trying to find a grand unified theory since 100 years ago.

Such efforts were crystallized as quantum field theory.

As the theoretical framework of the standard model of elementary particle physics, the Yang-Mills theory proposed by Chinese scientists Yang Zhenning and Mr. Mills as early as the 50s was an important step towards the grand unified theory.

The quality gap hypothesis is like the key to a treasure house.

The core difficulty in proving the quality gap hypothesis is not only the idea but also its extremely strict and precise requirements.

"For any compact, single gauge group, the quantum Yang-Mills equations in four-dimensional Euclidean space have a mass-gapped solution."

This is a rather special requirement of its mathematical version.

In fact, to fully unravel it, we need to construct a mathematical framework to prove that there is a non-zero minimum mass gap in quantum field theory. This is crucial for quantum chromodynamics and the same field theory.

Existing experimental evidence supports the theoretical language, but in order to fully meet mathematical rigor, it is still necessary to use pure mathematical methods to derive a dynamic model of vacuum and particle interaction.

The most suitable transmission methods are prime number theory and geometric methods.

Once someone can successfully break through, this general solution will be proved.

That would not only lead to major breakthroughs in theoretical physics, but would also develop quantum field theory into a new mathematical theory, which is a fundamentally different act.

Xu Qingshan also looks forward to being able to do this.

Because to some extent, he is the first person in the world to integrate prime number theory and geometric methods.

Xu Qingshan doesn’t have any literature on hand, and he doesn’t need to read any literature. He himself is the best literature.

Sitting at the desk, Xue Qingshan listed the first theory of prime numbers and geometric symmetry breaking, etc., which he wanted to use, in his manuscript.

On the other side were the new tools he had created.

He needs to find a point that can connect these things that seem to have little relevance, and create a framework container that can hold all the things in one place without any exclusion.

“Oh, it’s really difficult.”

Then, when Xu Qingshan faced such a problem, he also expressed deep emotion.

After sitting at the desk for an hour, Xu Qingshan didn't make any progress at all.

"Brother, you can come over for dinner."

Tong Tong greeted.

She actually wanted to call Xu Qingshan just now, but Xu Qingshan had been in a state of deep thought and she was worried that she would disturb him.

Fortunately, Xu Qingshan looked discouraged, so she felt comfortable enough to pull him over for dinner.

"What do you want to eat?"

Xu Qingshan's eyes were somewhat empty, and those seemingly irrelevant theories were still spinning in his head.

"Boiled live fish, that's not right, it should be boiled three delicacies."

Tong Tong distributed the bowls and chopsticks in his hand to the dining table.

Xu Qingshan then realized that Jiang Huanxi was still in the bathroom and had not come out yet. He had been thinking for an hour, and Jiang Huanxi had been taking a bath for just as long.

"Xiaoxi, hurry up and come out to eat, or it will get cold."

Xu Qingshan strolled to the bathroom door, tapped the bathroom glass gently and shouted.

"I know. It will be ready soon. You and Tong Tong can eat first."

Jiang Huanxi said in a soft voice, not knowing what she was doing in the bathroom.

"Sister Xiaoxi, this is your favorite boiled three fresh delicacies."

Tong Tong patted Xu Qingshan's arm, motioning him to move aside. She moved closer to the glass door and spoke softly.

"Clap."

The bathroom door was opened directly, and Jiang Huanxi, with her hair wrapped in a towel, rushed to the dining table in one step, looking at the boiled three fresh dishes with shining eyes.

Tong Tong raised his eyebrows at Xu Qingshan, as if to say, yes, this is what works.

Xu Qingshan shook his head.

It turns out that companionship is the most lasting confession of love. The longer you spend with someone, the better you understand him or her.

Now, Tong Tong and Jiang Huanxi are more familiar with each other.

The boiled seafood ordered by Tong Tong was very good and also suited Xu Qingshan's taste, but his eyesight was a little blurry when he was picking up the food.

He always felt that the piece of fish fillet in front of him looked very much like the first principle of prime numbers, the shrimp on the other end of the chopsticks was more like geometric symmetry breaking, and the cucumber and taro in his bowl were critical fiber bundles and quantum analysis.

Xu Qingshan almost slapped himself.

Crazy?
Can't even eat a meal in peace?
