The three generations of the Yu family are also quite legendary. From Yu Huazheng to his son Yu Yangguo, to his granddaughter Yu Qianqian, all of them are scientists, and the three have made outstanding contributions in their respective fields and are almost able to take on the main responsibilities in their fields.

Yu Hua is engaged in the study of conformal field theory in condensed matter physics, Yu Yangguo is engaged in the study of algebra, while Yu Qianqian is making breakthroughs in many fields of mathematics and has achieved good results.

However,

At this moment...the three people faced the general theorem of the periodic disturbance of the n-s equation that had just been completed by Fang Yun, and their eyes were filled with confusion and astonishment, as well as incredible expressions.

From Yu Yangguo's proposal to prove that viscous shock waves have nonlinear stability under periodic disturbances, to giving a suitable assumption that the oscillation of the same solution is carried in the far field, then there is this unique framework theory in the world. The whole process only lasted twenty-five minutes.

It sounds a bit incredible to build a grand cyclical disturbance theory building in a barren ruins in twenty-five minutes with one's own strength, but... someone did it.

if...

If this framework theory is completely correct, it means that the general theorem of periodic disturbance of the n-s equation will become the most important tool to solve shock wave stability in the future. This will be able to win the Fields Medal, and there is no suspense to win this top prize in the mathematics world.

"this..."

"Xiao Fang...this..."

As the vice dean of the Mathematics and Sciences of Jiangda University and the director of the Department of Mathematics, Yu Yangguo felt extremely shocked in his heart. He knew that his son-in-law was very powerful, but the scene in front of him was completely out of reality, and it was even a bit exaggerated...

"In fact, this framework theory is based on constructing synchronous oscillation approximation solutions of the solution, thereby overcoming the incompleteness..." Fang Han explained: "But its purpose is very narrow...it can only be used for the law of non-viscosity and viscosity conservation, and the stability of the solution under periodic disturbances."

Yu Yangguo picked up the first piece of manuscript paper and looked at the operators and processes on it carefully. The dense formulas made his scalp a little numb. From asking questions to establishing hypotheses to giving framework theories, these twenty-five minutes actually created a miracle in the field of mathematics.

"no..."

"How did you write this?" Although Yu Qianqian was also surprised, she was more confused. Her speed was so fast... so fast that she was dazzled. Often, she was still understanding the formula above, and he wrote three lines.

This gives people the feeling that it is a proof process on a manuscript, which appears directly on paper without thinking through the brain.

"Hehehe."

"Navi Stokes equation... I have studied it for a while, and even fantasized about solving the existence of smooth solutions in three-dimensional space. Of course... I studied loneliness from zero to zero." Fang Shi said with a smile: "But when solving the existence of smooth solutions in three-dimensional space, I have a deep understanding of the n-s equation."

"In addition, I am also very proficient in nonlinear partial differential equations. After all, it is necessary to use it in solid mechanics, so..." Fang Qi shrugged and said casually: "When a blind cat hits a dead mouse, he will hit it right away."

A blind cat hits a dead mouse?

Accidental?

When Yu Yangguo heard what his future son-in-law said, he directly denied it... This is definitely not as simple as a mistake. Without a strong foundation and wild ideas, such a magical operation would not be completed.

"Xiao Fang!"

"You are a little too modest." Yu Yangguo said seriously: "No joke... If this framework theory can be recognized by the masters of the mathematics community, you will become the top mathematician in our country."

However,

These words made Yu Huazheng present feel very uncomfortable. Xiao Fang is obviously a physicist, but has become the top mathematician in China. Why is it a bit of a bit of putting the cart before the horse?

"Ahem!"

"Xiao Fang... you must always pay attention to your identity, and don't be fascinated by this stupid name." Yu Hua said earnestly at Fang, "Mathematics... Just be fine, your main direction is physics."

For a moment,

The father and daughter were speechless, but they couldn't say anything. There was no way... After all, they were so old, and they quarreled with these things. If the high blood pressure soared, it was not a joke.

"oh..."

"Don't worry, Mr. Yu, life is a physical person, and death is a physical soul. I understand." Fang Qi nodded and said seriously.

But the words are over,

He quietly touched Xiao Aojiao's perky buttocks, which made Yu Qianqian blush.

"Xiao Fang?"

"Can you explain your process?" Yu Yangguo asked.

"no problem!"

Fang Qi quickly agreed, and then explained his framework theory to the father and daughter, and told them all the details in it without any reservation. After all, one is his lover and the other is his father-in-law.

This framework theory is actually very simple. The core is to construct an approximate solution of synchronous oscillation. By surrounding these two cores, a general theory is established. Of course... Fang Qi thinks it is very simple, but Yu Yangguo and Yu Qianqian, who received this theory for the first time, felt obscure and difficult to understand.

but,

I also have to admire Fang Qing's conceiving ability. Most people would not think of such an operation, so he... created this framework theory.

"It's time to eat!"

Aunt Wang walked out of the kitchen with a large pot of turtle soup and shouted to the four people on the sofa.

Then the six people sat happily at the dining table. Aunt Wang enthusiastically handed the turtles in the big bowl to the square bowl one by one, and threatened.

"Xiao Fang."

"This is a wild big turtle!" Aunt Wang said with a smile: "It's very nourishing, you can eat more... specially made for you. After eating the turtle meat, I will finish the soup. The essence is in the soup."

"grandmother..."

"I want it too." Yu Qianqian looked at it and said greedily.

At this time,

Zhou Min rolled her eyes and said to her daughter angrily: "What trouble is causing you? Eat something else!"

Yu Qianqian was so angry that she picked up a piece of white chop chicken, dipped it in some soy sauce, and put it into her mouth with a bite. The gritting teeth seemed to be not chicken in her mouth but the meat on Fang Qi's body.

"Xiao Fang."

"This framework theory...you will publish it in your personal name tomorrow, of course...the unit belongs to the Department of Mathematics of Jiang University." Yu Yangguo said: "Then you can help solve the problem about me. Just write it as a name, and the unit belongs to the Department of Mathematics of Jiang University."

Push open the car door,

Yu Qianqian couldn't wait to run over, hugged Fang Qi, who was opening the door from behind, wrapped her hands tightly around his waist, her slightly blushed face against his back, and her broad mind was squeezing her...

"Suddenly I don't want to go back..." Yu Qianqian pouted and said softly.

"Search for some time to confess to your parents... and then move in." Fang Qie said softly, holding her tender little hand.

"Um..."

Yu Qianqian closed her eyes, responded softly, and said softly: "Ruan Xiaomei is here to find me today."

"ah?"

Fang Qi was stunned for a moment and asked in confusion: "What did she ask you for?"

"What else can you do?"

"Of course I'm here to steal the man." Yu Qianqian's plump and vermilion lips were slightly tilted, and she said angrily with a look of displeasure on her face.

"oh."

"What happened later?" Fang Qing asked.

"Later...and she was shocked by my aura." Yu Qianqian said arrogantly: "Hmph! Even she dares to challenge me."

Fang Qi smiled, let go of her hand holding her waist, then turned around, hugged this proud body in his arms, and looked at the woman lying on her body, with a faint red glow on her handsome face, and said gently: "Of course... I don't see who she is competing for a man with."

After the words,

He asked carefully: "Will she expose the matter between us?"

"Won't."

"I don't think she dares." Yu Qianqian said confidently. After saying that... bit her lips and said softly: "Actually, she is quite pitiful. From chatting with her... I can feel the loneliness in her heart."

"Sensual loneliness?"

Fang Qi looked at her with a puzzled face and asked curiously: "How did you feel it?"

"This is a woman's intuition." Yu Qianqian turned her eyes on him and said angrily: "You stinky man's mind is full of breasts and butts. How can you feel the emotions deep in others?"

“Hehehe…”

"The inner is too obscure, I can feel the outer ones." Fang Qi looked at the woman in her arms with a bad face, hugged one of her hands on her waist, and quietly poked it down, squirting... and pressing it on her buttocks.

The next second,

The breathing broke the quiet atmosphere, and Yu Qianqian said shyly and angrily: "You want to die? Can you be more at peace?"

"Happiness is short, being able to be happy for a second is one second." Fang Qing said authentically.

For a moment,

Yu Qianqian was so angry that her scalp was almost numb. How did such shameless words come from her mouth?

"Be gentle!"

"This is not dough." Yu Qianqian said gritting her teeth.

"Don't worry, can you believe my technique?" Fang Qi said with a smile: "Baby...why is that pitiful Ruan Xiaomei?"

Yu Qianqian frowned slightly, glanced meaningfully, and said calmly: "What are you doing so much of a sudden? Do you want to heal her inner scars and then have something beyond friendship with her?"

"Oh, hey... I'll just ask." Fang Qing said helplessly.

"Curiosity kills the cat, don't ask if you shouldn't." Yu Qianqian said lightly: "I feel... the matter between me and her is not over yet, she will call me soon. I hope the next call will be what I expect... Hum~"

The lips are slightly opened, and the voice is hoarse and gentle.
