Two days later, Sun Erxiong gave pertinent advice.

"Shen Qi, in order for this semi-positive definite last inequality to hold, it is necessary to reduce Δ and δ, and I give the following equation for reference only. ”

The formula is written on the printed version of Shen Qi's paper:

‖xk+vksk-x‖＜δ’

‖xk-x‖≤δ＜δ’

......

After reviewing Shen Qi's paper, he burned many of Sun Erxiong's brain cells.

"Thank you, Professor Sun, for your advice, I'll change it right away. ”

Shen Qi quickly finished the paper, and sent the final PDF document of "Analysis of Generalized Nonlinear Complementarity Problems Constrained by Linear Inequality" to the mailbox of "Math Review".

"Review of Mathematics" is a core journal of mathematics sponsored by Yan University, with an IF of 0.492, ranking 2nd-4th among similar journals in China.

The first place is the "Acta Mathematica Sinica" supervised by the Chinese Academy of Sciences, which is a recognized fact in the industry, and the reviewers of the "Acta Mathematica Sinica" will arrange for the academicians of the Chinese Academy of Sciences to do it from time to time, and no one in China has their authority.

"Annals of Mathematics", "Progress in Mathematics", and "Review of Mathematics" are second only to "Acta Mathematica Sinica", and the rankings of these three are actually in no particular order, they are all 2-4.

Shen Qi submitted the most high-grade of the five papers to the "Mathematical Review" to take care of Yanda's own business.

The next thing is to wait, Shen Qi hopes that the paper submitted to the "Mathematical Review" can enter the peer review link before the Spring Festival.

Of course, the time is a bit rushed, and today is December 10th.

On January 28th, the New Year's Day, the editorial board of the journal estimated that there would be a holiday on January 10th, and they would go to work after the Lantern Festival.

The Spring Festival can't advance the peer review process, and after the Lantern Festival, they will grind again, and the paper will really be accepted, and it may be in March or April next year.

But it's useless to rush such a thing as a math paper review.

Shen Qi's first paper was "A Solution to Three-Dimensional Hypercomplex Numbers", which was submitted to the "Mathematical Research Journal" sponsored by Zhejiang University, and that day was November 3.

On November 6, Shen Qi received an electronic receipt from the Journal of Mathematical Research: "Hello author, I have received your manuscript, please wait patiently for the contact of the editor." ”

Acknowledgment of receipt is a routine procedure, which does not indicate whether Shen Qi's paper was accepted or rejected.

It can only be said that Shen Qi, your paper manuscript has been successfully sent to the journal's mailbox and has not been eaten by the virus.

It will not be a clear answer until the day the editor contacts Shen Qi whether to enter the peer review process or be rejected.

From November 6th to today, more than a month, the editor has not yet contacted Shen Qi.

It's also normal, wait.

Today's Ma Zhe results are out, and students can check them on the intranet.

Shen Qi checked, 97 points.

Ask the three roommates about their Ma Zhe scores, Zhou Yu'an 87 points, Cai Qing 94 points, and Luo Ji 92 points. No one got a perfect score.

If I asked the other students in the Department of Mathematics, the highest score was 98 points, which was from Ouye. None of the entire department got a perfect score on Ma Zhe.

Obviously, Teacher Chen Xinhong is determined not to give full marks to anyone.

97 points is 97 points, Shen Qi can only accept this objective fact. Goodbye Teacher Chen Xinhong, I will never have to take your classes again in the future, and I will get 2 credits.

"It's unreasonable, this stepping on the horse is too unfair!" Zhou Yu'an was aggrieved to death, beating his chest and stunning, unable to eat angrily.

There were four people in the dormitory, and Zhou Yu'an attended the last Ma Zhe class before the exam with a strong sense of responsibility, and made three copies of the key points of the exam and distributed them to the three roommates.

As a result, the kind-hearted Zhou Yu'an only scored 87 points, the lowest in the whole dormitory.

"Good people don't have good rewards!" Zhou Yu'an covered his face, very painful, he hated himself.

It's noon, Yan University canteen, Shen Qi, Zhou Yu'an, and Ou Ye have lunch together.

Ou Ye is the most hanging, she has never taken a class from beginning to end, and Ma Zhe scored the highest score of 98 in the whole department.

Shen Qi didn't speak, he looked out of the window in distraction.

"Shen Qi, you are talking, I'm so angry! In the future, you will copy the key points of the exam yourself, don't expect me, you are the squad leader, bastard, I am just the substitute squad leader, Lao Tzu is gone!" Zhou Yu'an forcibly snatched a chicken leg from Shen Qi's dinner plate as compensation for the psychological trauma: "Hey, Shen Qi, are you stupid? What are you looking at?" ”

Shen Qi finally spoke: "It's snowing." ”

"When it snows, it snows, what's so strange, it's December, it's time to snow. Zhou Yu'an took a bite of the chicken leg fiercely.

Shen Qi: "I've never seen real snow, this is the first time, the snowflakes are so beautiful." ”

"Huh?" Zhou Yu'an was stunned, "No, I haven't even seen snow, you African?"

Shen Qi said: "It doesn't snow in my hometown, and it doesn't snow in the cold winter. Of course, I've seen snow on TV, and I've traveled to the north during the summer vacation, but I've never been to the north during the winter vacation, so I've never seen real snow. ”

"Poor child, I haven't even seen real snow, Shen Qi, I'm finally a little better than you, I've seen real snow since I was born. Zhou Yu'an found a trace of spiritual comfort.

Shen Qi stood up: "Let's go, play in the snow." ”

"Childish. "Zhou Yu'an didn't go.

"Let's go, play in the snow. Shen Qi said to Ou Ye.

"Oh. Ou Ye and Shen Qi left the cafeteria, and the two came outside.

Today's snow is the first snow in the capital after the beginning of winter, not big, not small.

Shortly after the snowflakes fell, there was no snow on the ground, and there was actually no snow to play with.

"Have you ever seen real snow, Oye. Shen Qi asked, spreading out his palms to catch the falling snowflakes.

Ou Ye put his hands in his coat pockets and shivered in the snow: "Yes, I grew up in the north. ”

Shen Qi took off his coat and draped it on Ou Ye very naturally: "I'm sorry, I forgot that you are not in good health, you go back indoors, I will experience the snow in the north alone." ”

"You're not cold?" Even though she put on Shen Qi's coat, Ou Ye still felt cold, but she didn't immediately return to the heated room.

"I'm a long-distance runner and I'm in good shape. Shen Qi smiled, and he spread his hands again to catch the snowflakes.

The snowflakes melted quickly in Shen Qi's palm, and they only existed for an extremely short moment.

"The snowflakes are really beautiful, it's in a regular hexagonal shape, it's perfect. What's amazing is that there are snowflakes flying all over the sky, a large number of hexagons, and no snowflakes are exactly the same, Ou Ye, don't you think this is amazing?" Shen Qi said, "Is there a mathematical means that can qualitatively describe the law of the distribution of snowflake shapes, so as to find a snowflake CP that is exactly the same from one to one?"

Oye: "Someone has done that, Cork. ”

"Well, yes, Cork's snowflake curve could be further optimized. Hey, Ouye, let's do a project together, the topic is called 'A Calculation Method of Snowflake Curve', what a beautiful subject. This topic should require a lot of calculations, and the calculations are left to you. Shen Qi had a whim, and thought that this topic was quite interesting.

"Ahh

"Okay, okay, I'll just talk about it, let's not study this snowflake topic. Shen Qi forcibly pushed Ou Ye into the cafeteria and instructed: "Don't come out, come out again when the snow stops." ”

Ou Ye took off Shen Qi's coat and threw it to Shen Qi: "Don't play for too long." ”

After Ou Ye finished speaking, he rubbed his frozen hands and entered the cafeteria.

Shen Qi put on his coat and stood in the snow looking up at the sky, like a statue, letting the wind and snow erode my young and resolute face.

Ahh

Shen Qi sneezed.

"This is contagious too fast, isn't it?" Shen Qi wiped his nose, he didn't pretend to be B, he was a little cold.

Just as he entered the canteen to escape the cold, he walked to the door of the canteen, Shen Qi's mobile phone rang, and Xu Rui called.

"It's snowing, it's snowing, it's snowing!" Xu Rui hadn't seen real snow either.

Shen Qi said calmly: "When it snows, it snows, what's unusual, it's December, it's time to snow." Xu Rui, mature point, you are not a child, you are a few months older than me. ”

"Shen Qi, come to my school, hurry up and save me!" Xu Rui's voice sounded anxious.

"Damn, you're fighting with people again! What is the specific part of science and technology, send a location on WeChat, and I'll come over immediately!" Shen Qixin said Xu Rui, Xu Rui, you fought from the south to the north, and fought all over the world? You are practicing track and field, not sanda!

"What are you fighting? This materials major I studied, damn it, it's a pit!" Xu Rui was very desperate, "This broken major has to learn materials science, inorganic chemistry and organic chemistry, and I have to learn physics and engineering drawing, I'm Nima...... I've been abused into a mentally retarded person! I've left my hometown and come to the capital, I'm looking for abuse! Shen Qi, you are the most awesome student, only you can save me, come over quickly!"
