At this moment, Shen Qi entered a state of selflessness.

He ignores everything except mathematics.

The students coming and going, the aunt who packs the tableware, and the couple showing their love not far from next door.

Air is all air.

Illusion, all are illusion.

Then what is reality?

This paper can be finished, which is the most real thing.

"It is said that the Chinese academic world is chaotic, and I can't see it all. This weirdo from the Mathematics Academy is a clear stream in the academic world. I don't know what problems he is thinking about, but I think it must be related to mathematics. It is rare to think about mathematical problems these days to reach the state of meditation." The girl still couldn't help but speak and chatted with her engineering boyfriend opposite.

"Qingliu? He is the most dangerous mudslide in Quanyan University. I have never seen such a freshman who pretends to be a B." The engineering man is so annoyed. Shen Qi, you are so jealous. You can see you everywhere. Running and catching my circle, eating and flirting with my sister, forcing me to pretend to be a B, and people and gods are angry!

"Hey, are you just a sophomore? How many freshmen have you seen?" the girl smiled, skillfully peeling off a shrimp and putting it on the plate of the men's ticket.

"Let's go and watch a movie." The engineering man didn't want to stay here for a minute or a second longer.

"The pixie shrimp hasn't been finished yet. Let's leave after eating. Don't waste it." The girl continued to peel the pixie.

Faced with the logic problem of generalized Jacobian matrix algorithms of semi-smooth systems of equations, Shen Qi was about to collapse, without any ideas, and at all.

In fact, there are too many ideas and so many mixed ideas.

The phone vibrated, Shen Qi took it out and took a look, and Ou Ye sent a WeChat message: "The Algorithm of the Feature Equation of a Class of Determinant" has been completed, can it be changed?"

Below the dialog box is an attachment, df.

Shen Qi was inexplicably stimulated. In less than four days, Ou Ye finished a paper?

Click on the PDF paper document, Shen Qi quickly reviewed it. The paper title is "Algorithm for the Feature Equation of a Class of Determinant", which he took.

The rest of the work except the title of the paper was completed by Ou Ye and based on the outline of Shen Qi's thesis.

Shen Qi-Ou Ye

Department of Mathematics, School of Mathematics, Yan University-Capital-100000

Abstract: This paper uses the inertia of variable quadratic types to give an algorithm for a class of determinant feature equations, and considers some of its special results.

Keywords: determinant, quadratic, eigenvalue

The paper jointly drafted by Shen Qi and Ou Ye is neat in format and rigorous in the discussion, and basically everything that should be written is written.

Ou Ye was very attentive, and she quoted all the papers in the Polish math journal "studia-math" in 1970.

In that era, under the influence of the Soviet big brother, mathematical talents emerged from Central and Eastern European countries such as Poland, Romania, Hungary, Yugoslavia, and East Germany. The papers they wrote are still out of date in the 21st century.

"There are a few places that need to be slightly modified. I can't explain clearly on WeChat, so I'll learn a canteen." Shen Qi replied to Ou Ye for information.

Not long after, Ou Ye brought his laptop to Xueyi Canteen, found Shen Qi, and sat next to him.

Looking at the steamed buns on the table, Ou Ye’s notebook had no place to put: “Matrix?”

"Can you understand the meaning of this matrix?" Shen Qi asked.

Ou Ye shook his head: "It's too difficult."

Shen Qi packed the steamed buns into the dining plate and asked Ou Ye to put his laptop on the dining table.

"Ou Ye, your hand speed is faster than mine." Shen Qi was a little surprised. "Last year, at Jinqiu Camp, when we first met, you introduced yourself. My name is Ou Ye, Ou is Ou of Ou, and Ye is Fourier's Ye. Your name is wonderful. Ou is your brother, right? The most powerful feature of your Ou family is that you can write the paper and fly up."

"You built the frame, so hurry up." Ou Ye said.

"Let's stop yelling at each other. Let's talk about this paper we jointly signed. In fact, most of the work is done by you, and I'm just checking it." Shen Qi operated Ou Ye's laptop and pointed to the latex document on the screen and said: "Here, we need to consider the classification of quadratic curves and quadratic surface bundles. The determinant (11) needs to be changed."

"Yes." Ou Ye understood in seconds.

"And here, the biggest common factor of the i-order formula is generally not expressed in this way, so change it."

"Full set of invariants?"

"Yes, the amount of changes is not large, it is a revision of the local expression."

"oh."

"I won't check the calculation part correctly. I don't have time to calculate it again. I believe in your calculation ability." Shen Qi had a deeper understanding of Ou Ye's academic characteristics. As long as Ou Ye understands his logic, Ou Ye can quickly complete a paper, and the compliance is above 95%.

"Where to vote?" asked Ou Ye.

Shen Qi said: "If you find a core journal to invest in, except for the top four in China. If the paper is signed with my name, it is not a big problem. After all, I am the one who has published the paper. If this paper is passed, you will become a person with academic capital."

"Okay." Ou Ye nodded and asked again: "Are you in bad spirits?"

Shen Qi said with a tired face: "Just the question 23, I encountered great confusion when writing the thesis. My logic was useless. It was inconsistent. After a few nights, I felt tired."

"Take it slow." Ou Ye said, closing her notebook: "It is not advisable to stay up late for a while."

"Do you think I want to stay up all night..." Shen Qi smiled bitterly, and in an instant, yes, in just a moment, he suddenly got a fleeting inspiration: "What did Ou Ye say? You say it again?"

Ou Ye: "I...I didn't say anything."

Shen Qi was full of red light, and his eyes were shining at Ou Ye's eyes: "Get back, the last sentence you said just now."

"It is not advisable to stay up late for a while?" Ou Ye was a little worried. Is Shen Qi so obsessed with it?

Shen Qi grabbed Ou Ye's upper arm with both hands and shook it excitedly: "Ou Ye, what you mean is that continuous cannot be subtle... No, should it be discontinuous cannot be subtle?"

Ou Ye's eyes were shaken and his little star appeared: "No, I didn't say that."

"Yes, what you said makes sense. Although the common nature of Φ is that h is differentiable, Φ is differentiable in r^n! I thought of it, I finally thought of it, haha! Ou Ye, you are very casual, 666!" Shen Qi shouted, and then ran away. He was going back to complete his paper. The most core logic appeared, starting from accident and becoming inevitable.

"Shen Qi...you..." Ou Ye looked at Shen Qi running away and murmured to himself: "Crazy, I can't help but crazy."

The couple not far from next door witnessed all this, and they stared at each other.

"What are they doing with this Shen Qi and this Ou Ye?" The girl studied liberal arts. She couldn't understand what Shen Qi shouted to solve the problem, but she just looked very powerful.

The engineering man is also a top student, and he can understand something: "I just said that there is no normal person in the Mathematics Institute. They are in a team and they are crazy."
