Xueba: I study hard in the wasteland world

Chapter 137 135, graduation thesis and the Spring Festival are approaching
  Su Yu and Xia Ning walked into the library together.

As soon as she walked into the library, Xia Ning no longer chattered like before and turned into a quiet and beautiful woman.

Time seems to have returned to their undergraduate days, when Su Yu and Xia Ning went to the library to study together. It was beautiful and quiet.

Su Yu and Xia Ning found a seat by the window and sat down. Xia Ning found a latest journal document and read it carefully.

Su Yu glanced at Xia Ning, spread out a piece of white paper, and began to sort out the knowledge that was filled in her head by the old professors in the wasteland world!

These old professors are very annoying. The knowledge system of the wasteland world is not completely connected with the knowledge system of the real world. The old professors don't care and just "feed" Su Yu.

Now that Su Yu's head was in a mess, he needed to hurry up and sort it out, and then hurry up and write his graduation thesis.

Time flies so fast, and the winter vacation of NPU has begun.

Recently, although Su Yu's daily life is just two points and one line between home and school, Su Yu's life is very fulfilling. His materials science thesis has been completed. The title of the thesis is - "SY7 Fluoroborate" Analysis of SY spectral data of glass materials.

This paper published in the "Journal of Su Yu Materials" instantly shocked the world as soon as it was released. In the paper, Su Yu further decrypted the "secret" of "Fruit Candy Glass" to the world.

Of course, the "decryption" is there, and other laboratories still have a long way to go if they want to develop materials that can generate electricity from fruit candy companies.

Moreover, the Fruit Candy Company has also completed its global market layout. Even if other laboratories develop the same self-generating materials as the Fruit Candy Company, the "road" has already been occupied by the Fruit Candy Company. If others want to leave, they have to Follow the "Fruit Candy Group" and follow the "Fruit Candy Standard".

The graduation thesis on materials science was completed, and Su Yu already had a direction for the next graduation thesis on physics:

Since Su Yu completed the proof of the NS equation, human mathematics and physics have acquired new tools and developed rapidly. The physics paper Su Yu wants to write is about the application of the NS equation in mathematics and physics.

NPU is on winter vacation, and Su Yu has returned to her hometown in Jiaodong.

Originally, Su Yu planned to study at home during the winter vacation and complete her mathematics thesis! But it turns out that home is not a place to study, and Su Yu can't study at home at all!

Fortunately, Su Yu's home is very close to Jiaodong University, and in order to provide citizens with study convenience, the library of Jiaodong University is open to the public during the winter vacation!

So, Su Yu sat in the library of Jiaodong University.

After sitting in the library and picking his hands for a while, Su Yu sorted out his knowledge system in the wasteland world and the real world in his mind, and started typing on the keyboard.

Soon, Su Yu typed out the title of the mathematics paper on a blank word document: "Symmetry Analysis Based on Alloy's Group Theory Theorem".

Su Yu’s mathematics paper is about group theory!
  Group theory is a mathematical concept.

In mathematics and abstract algebra, group theory is the study of algebraic structures called groups.

"Groups" have a fundamental importance in abstract algebra: many algebraic structures, including rings, fields, and modules, can be seen as being formed by adding new operations and axioms on the basis of groups.

The concept of "group" appears in many branches of mathematics, and the research methods of group theory also have an important influence on other branches of abstract algebra.

"Group theory" sounds like an enigmatic and high-level mathematical concept at first glance!
  When Su Yu heard the name "Group Theory" at the beginning, it was like contacting "Line Generation" for the first time. He was frightened at first impression and thought it was difficult.

But when she settled down and studied seriously, Su Yu felt that it was still very simple, just a branch of mathematics! The reason why Su Yu wanted to write a paper on group theory was because he wanted to try another "np-complete problem", which is "one of the seven major mathematical problems in the world".

Group theory plays a great role in computer science and can be applied to fields such as cryptography, coding theory, and graph theory. It will be helpful to Su Yu's deeper understanding of the "NP-complete problem"!
  When Su Yu first started writing the paper, it was as hard as squeezing the water out of a sponge. Now his head is full of knowledge. When Su Yu writes any paper, his ideas are extremely smooth:
  The direct product generates an ordered element group: X*Y={(X, Y)|x∈X, y∈Y}
  Tensor product constructs a higher-order tensor: v⊕u⊕M→vuuvMρ=Tμνσ→T
  The matrix expression of the direct sum is:
  Following the method of using assemblage sets to segment groups, conjugate classes are used to segment group solutions.
  Although the verification process was very troublesome, the ideas were all in Su Yu's mind. All he had to do was to be cautious, write down the symbols and operations of each step clearly, and make every logic smooth.

Time passed by, and Su Yu quickly finished typing out a chapter of the paper. The draft paper in front of him was also filled with various calculation formulas and mathematical symbols!
  "Not bad, the progress is going very smoothly. I will try to finish the paper before the Spring Festival!"

After writing the paper all morning, Su Yu stretched out, raised his head and looked around the full library. Su Yu still felt good.

Now during the winter vacation, students are out of school, and those sitting in the library studying are citizens of all ages.

China's economy is developing rapidly, and similarly, the demand for knowledge from all walks of life is also developing rapidly.

When the "involution" of "devaluation" of hard work disappears, every point of effort will be rewarded by 10 points. There is no need for others to tell you, and everyone in all walks of life is consciously working hard.

At noon, Su Yu had a simple meal outside, and continued to spend the afternoon in the library. She didn't come out of the library of Jiaodong University until dark.

When Su Yu came out, an Audi car was already waiting for him at the entrance of the library. After getting in the Audi car, Su Yu went home.

"Xiaoyu! What's going on between you and Xia Ning!"

As soon as Su Yu came home, she was greeted by her mother's nagging. She didn't care about Su Yu's studies, let alone Su Yu's work, she only cared about Xia Ning!
  "Oh, it's just like that, so annoying!" Su Yu complained to her mother impatiently, and then went back to the room!

Mother Su is very anxious! Especially since Su Yu and Xia Ning have yet to confirm their relationship!

"Mom, your window grilles are all crooked!"

When Su Yu got up in the morning, she saw the Spring Festival window grilles on the windows at home, and then she realized that the Spring Festival was approaching!

"Oh, yes!"

Mother Su, who was mopping the floor, saw that the window grilles were really crooked, so she immediately went over to play with them!

Lying on the sofa, eating melon seeds and scrolling through her cell phone, my sister Su Qi looked at the flagpole unhappily. Su Yu, who was tall, said, "You are blind! You are so tall, you can't go over and help mom straighten the window grilles!"

After looking at her sister, Su Yu immediately replied: "Then why don't you go!"

Su Qi made a fierce gesture as if she wanted to hit someone, and said to Su Yu: "You deserve a beating! Go and help mom get it!"

"Humph!" Su Yu gave her sister Su Qi a roll of her eyes, and then reluctantly helped her mother play with the window grilles!

The annual Spring Festival is approaching, and not only Su Yu’s family, but also the entire Jiaodong city has begun to have a lot of new year flavor!
  Especially in Jiaodong City, the "bang bang bang" road construction all over the place finally stopped before the Spring Festival!
  In recent years, although the economy of Jiaodong City has been developing at a rapid pace, citizens have complained:
  In the past few years, roads have been built throughout the city and dead ends have been opened;

In the next two years, the city will build a beltway network and expressways.

Now that the road network has finally been repaired, the citizens have been struggling for a few days. Well, Jiaodong has begun to close roads everywhere again to build subways!
  Thanks to the fact that the leader of the city in recent years is Su Wenbin, Su Yu's father, everyone knows that a family with "the richest man in the world" is not short of money. Otherwise, the citizens of the city would have scolded him even more fiercely!

However, I heard that after the Spring Festival, Su Wenbin will be transferred to another province. Thinking of his great contribution to the city in recent years, the citizens are still a little reluctant to part with him!
