Xueba's Resurrection

Chapter 13

Books have become Otokawa's daily necessities, and he feels uncomfortable if he doesn't read them all day.

Reading and studying mathematics during the day to develop the brain is the most fundamental and most important thing. It is related to the opening of the black technology system, and we have to spend a lot of energy.

Just like building a house, if the foundation is not solid, no matter how beautifully built the house is, it cannot withstand the ravages of a typhoon.

Squeezing wool to obtain energy points is an auxiliary, and in the end, all energy points must be used in the black technology system.

We cannot put the cart before the horse.

Moreover, those ghosts and monsters will only come out when it is dark!
Midnight games are very suitable for Little Brother Yi's appetite.

Maybe it will expand to supernatural games such as Pen Fairy, Bloody Mary, Mirror Witch in the future, if energy points can be obtained.

And during the day, go to the library!
Even though the school is on holiday in July, the library will still be open regularly, but there is no campus card, which makes Otokawa a little worried.

Live and learn.

The ancients said that there are thousands of millet in the book, the house of gold in the book, the beauty in the book, black technology in it, and knowledge is strength.

Yi Xiaochuan was originally a scumbag, but after many days of systematic transformation, he has become completely obsessed with studying.

Brushing books is addictive, especially when you see a little change in experience value, you have the pleasure of fighting monsters and upgrading.

Compared with before the mathematics was upgraded, Yi Xiaochuan basically didn't need to consume energy for reading, and he could enter a shallow state of concentration by his own will.

Of course, this effect is incomparable to that of turning on "Concentration", and the efficiency is slightly insufficient.

In one morning, the experience value was only pushed from 1% to 3%, and the progress was worrying.

At noon, the library will be closed. From 12:14 to [-]:[-], it took Xiao B more than half an hour to eat, and he walked around the three canteens, and his stomach was finally satisfied.

Originally, if there was a dormitory, I could take a nap, but now, I just wander around.

The weather at the end of June absolutely makes people not want to stay outside for an extra minute.

Xiao Yi was no exception, she couldn't help it because of the heat, so she buried herself in a shady building.

"School of Mathematics? Well, it seems that I really have a relationship with mathematics!" Look at the time, it's only one o'clock, so let's go shopping!

Maybe I can still meet professors from the Mathematics Academy, and I can ask for advice. Anyway, my Xiaoyi is not what it used to be now.

At this time, a young man with a worrying hairline came in from the outside sweating profusely, carrying a box of lunch and a bottle of iced Coke in his hand, his eyes were bloodshot.

Walking to Xiaoyi's side, he was stunned for a moment, and then asked uncertainly: "Student, aren't you Zhang Lisong's roommate?"

"Huh?!" Xiao Yi looked away from the portrait of the mathematician on the wall, and the hairline of the young man in front of him had actually moved closer to the figure in the portrait.

"Yes, I'm Zhang Lisong's roommate, you... oh, you're from his hometown! You're a graduate student in the School of Mathematics, two years older than us, we've met..."

"It's hot outside, come in and have a seat, come, drink some water!" As he said this, the brother with an attractive hairline handed over the ice coke in his hand.

Xiao Yi waved his hand immediately and said: "Brother, you are welcome, I just had enough..."

In the end, Brother Hairline took a disposable paper cup, poured a cup of Coke and handed it to Xiao Yi, and chatted while wolfing down the meal.

"You don't know..." Brother Fajiexian swallowed his meal, scratched his hair, and complained in a low voice: "My boss is going to drive me crazy! Throw me a few books on analytic number theory and say no." I learned something in the direction of prime numbers, but I failed his assessment. I may... no, I will definitely not be able to graduate next year! I, Zheng Hui, believe that I have worked hard in the past two years and brought a lot of economic benefits to my boss. How about this? God is going to kill me! If I have the ability to study basic mathematics, I am still doing a graduate student here, and I have already taken the 211 and 985 exams..."

Yi Xiaochuan blinked his eyes and looked at the hair on the top of his head. If he scratched it, would he be really bald?
"Huh? If I remember correctly, isn't the direction of the master's graduate student financial mathematics? Why do you study basic mathematics? It's still the direction of prime numbers!"

In a second-rate science and engineering school, it is unrealistic for master students majoring in mathematics to concentrate on studying basic mathematics, and no one will apply for it, because employment is really worrying, and maybe even the tutors may not have research results that can be sold.

But financial mathematics is different.

This is an emerging interdisciplinary subject of finance and mathematics. The biggest feature of this subject is the use of mathematical models to explain and study financial issues.

It sounds like you are tall, dealing with money and finance, can you still be short of money?
"What can I do? The boss personally issued an order with a serious face. The company's projects have all stopped. He even gave us classes every day, assigned homework, and even corrected his mother himself. The sun is really going to come out from the west... Alas! I can only eat slowly, there is still one year, I hope it will pass!" Brother Hairline threw the disposable lunch box into the trash can, and then took out a large copy of "Basics of Analytical Number Theory" from the table. There is nothing to love about the face.

Xiao Yi took a glance, Analytical Number Theory Fundamentals (Second Edition), Harbin Institute of Technology Press, Author: (Russia) Kara Chuba, Translator: Pan Chengbiao, Zhang Nanyue.

It's the same book I'm reading now.

A lot of doubts arose in Oto Xiaochuan's heart. The abnormality of the professor of the School of Science and Technology could not be related to the recovery of spiritual energy and the awakening of evolution, right?

Definitely related.

The country's macro-control may focus on extraordinary research.

The foundation of all subjects is mathematics.

Every time there is a major breakthrough in mathematics and a mathematical problem is overcome, it is unimaginable for the improvement of the entire technology.

Xiaoyi also studied mathematics alone for several days. Today, he met a graduate student from the School of Mathematics, and felt that he could just verify what level his current knowledge is at.

"Brother, do you have any research on Yuanfa?"

Why?

Brother Zheng didn't come back to his senses, you from the School of Biochemistry, ask me what research I have on Yuanfa?
I'm just complaining!Venting and venting is beneficial to the body and mind, and why do you study methods...

Xiao Yi blinked in confusion, and said uncertainly: "The three important methods of analyzing number theory are the complex integral method, the circular method, and the trigonometric sum method. I am studying the circular method, and I have some doubts about it. Brother can give me some pointers." ?"

"Hi..." Senior Brother Zheng hiccupped, feeling that it shouldn't be too advanced for someone who studies polymers to ask himself a graduate student in the School of Mathematics about Yuanfa, but brother is also a good face!

What if you make a mistake?
Seeing Xiaoyi's sincere expression, Senior Brother Zheng nodded and said, "Tell me, the circle method is an important method for studying number theory. Although I have just started, the problems of ordinary undergraduates are not difficult for me... "

Otokawa took out a piece of white paper from the table, took a pen and said: "In analytic number theory, we often use the so-called Merlin transform, which is actually another way of writing the Laplace transform. If we consider the Gaussian function multiplied by a trigonometric function, we get what's called a parabolic cylindrical function. I don't know much about it, and I know some asymptotic estimates, but no definite constant, no definite error term...how Using the circle method to study this problem, my idea is..."

Looking at the formula written smoothly by Xiao Yi's pen tip, the dignified graduate student of the School of Mathematics is already in a daze...

what am i doing?
What are you doing again?
Xiao Yi looked up at the senior's expression, stopped writing, coughed lightly, and said, "Well, I don't know what experience brother has on the distribution of prime numbers?"

"..."

Fine beads of sweat gathered together on the smooth forehead to form a sweat drop, and Gulu slid down from the corner of his eyes like a crystal teardrop!
