Chapter 34 Thesis is ready

For five consecutive days, Li Mo has been writing in the small corner of the library A paper on the four-color conjecture. He is only now discovering how difficult it is to write a paper in a foreign language.

Professionalism of words, normativeness of quoted theorems. He had thought vocabulary was the most difficult. In fact, when writing a paper, I discovered that vocabulary is not the most difficult thing, the real trouble is the logic expressed in foreign languages.

After consulting countless literatures and racking his brains, Li Mo finally wrote the complete thesis.

We can convert the four color conjecture,

At the same time, we call the number of points of the largest complete graph subgraph included in Figure F as “clique number”, and note it as X. It is easy to find that a complete graph of n points requires at least n different colors because the two points are adjacent

It is obvious from the above that any part of a graph is divided and dyed to make any part with common sidelines have different colors, and can only use four colors, no more. The proposition is true.

I have finished the certificate.

Watch Li Mo was very satisfied with the thesis he wrote, just like seeing his own child.

Li Mo remembered Wei Xiaonian’s words, he took out his mobile phone and dialed Professor Wu’s number: “Professor Wu, hello, I am Li Mo, I have recently completed a paper. Let you check first.”

“Thesis? Okay, okay, I’m free in the afternoon, so come to my office at two o’clock in the afternoon.” Professor Wu replies while taking the documents handed by his assistant. .

The female assistant in a professional sleeve skirt saw the professor put down the phone and whispered, “Old Wu, you have a meeting with Mr. Zhang from Dafang Group this afternoon, do you think so.”

“Push it down, just say I’m busy in the afternoon.” Professor Wu replied while looking at the document.

The female assistant nodded her head and wondered, “Who is the student on the other side of the phone? How could Old Wu push the meeting in the afternoon? Dafang Group invests a lot of money in the Department of Mathematics every year. What.”

Li Mo carefully checked his paper several times, and then cautiously put it into his schoolbag.

The fatty next to Li Mo asked curiously when he saw Li Mo’s cautious behavior: “Mozi, what’s in the bag, take care of you and show it to my buddy.”

Li Mo replied without looking back: “Thesis.” After that, he left the dormitory with his schoolbag, and he had to go to the library to continue the liver book.

fatty looked at Li Mo’s back a little bit. Strange: “I started writing my thesis in my freshman year? Is the youngster really that fierce now?”

At two o’clock in the afternoon, Li Mo came to the office building of the Department of Mathematics on time, and he knocked on the office of Professor Wu. The door opened, but it was a beautiful young woman wearing a sleeve skirt.

The young woman opened the door and asked softly, “Classmate, who are you looking for?”

Li Mo said, “Professor Wu invited me to come at two o’clock, is he not here?”

The young woman’s eyes lit up, she gently let Li Mo into the office, and said, “Professor Wu just went out, come back soon, you wait.”

Then she He hesitated and added: “I’m Professor Wu’s assistant, my name is Fang Xiaoyun, may I ask classmate who are you?”

Li Mo said generously: “I’m Li Mo, nice to meet you.”

The two were chatting when Professor Wu pushed the door and came in. He saw Li Mo and said happily: “Come inside, let me see your paper.” He turned around and explained to the young woman.” Xiaoyun, make two cups of tea.”

Professor Wu put on his glasses and looked at the paper handed over by Li Mo, and after reading only one title, he started: “Four-color conjecture? Do you really conjecture the four-color conjecture? The proof is out?”

Professor Wu’s movement shocked the young woman who was pouring water, and the boiling water spilled on the floor. She was about to use the mop to dry her, but was stopped by Professor Wu: “You go out first, and push off the schedule for the afternoon for me.”

The young woman nodded her head and looked at it carefully. Take a look at Li Mo.

Professor Wu made sure that his assistant had left, so he started to read the paper.

Li Mo could see that foreign languages were no obstacle for Professor Wu in front of him.

“Ingenious, the changes you have made here are really amazing.” Professor Wu said with admiration as he looked at the paper.

Li Mo sat in the chair calmly, like a student waiting for an exam. He looked at the opposite Professor Wu and sometimes frowned, sometimes with a smile, but he didn’t feel a little nervous in his heart, because he was very confident in the paper he wrote.

“Is there a miscalculation in your coordinate system? Why does this place look so strange?” Professor Wu frowned pointed to a determinant and said.

Li Mo smiled and took a piece of paper from the side, wrote two lines of calculation formulas on it, and handed it over.

Professor Wu saw the calculation formula on the straw paper, patted his head and said, “It’s so ingenious, what do you think?”

“Eagle and hedgehog.” Li Mo Said frankly.

“Eagle and hedgehog?” Professor Wu couldn’t understand, “Let’s look at the paper first, is there something wrong with your constant term?”

Li Mo turned the paper to On the second page, he pointed to the above few lines of calculation, and Professor Wu’s doubts disappeared.

Professor Wu read the paper carefully. If there is any doubt, he wants Li Mo to explain it. Fortunately, so far, he has not found any mistakes in Li Mo’s paper.

“gu lu .gu lu “Unconsciously, several hours had passed, and Li Mo’s stomach rang.

Professor Wu looked at Li Mo, who was embarrassed, put away the paper, and used the internal phone to explain that the assistant had brought two takeaways.

“Tell me your main idea.” Professor Wu was still thinking about his thesis while eating takeaway.

“I transformed the four-color conjecture of the plane into a three-dimensional coordinate system.” Li Mo explained in detail.

Professor Wu looked at Li Mo lovingly and said, “Ingenious, really ingenious, how does your brain grow?”

At ten o’clock in the evening, under Li Mo’s explanation, Professor Wu finally read through the paper. He flipped through the more than 50 pages of the paper and was surprised to find that he could not find any mistakes.

“You completed this thesis independently?” Professor Wu asked, taking a sip from the teacup.

“Yes, the main idea took about a month, and the writing took about a week.” Li Mo nodded and answered honestly.

Professor Wu looked at Li Mo’s candid face, and said nodded: “I think you did it yourself. If you wrote it with the help of a professor, you would definitely not be the only one who signed it. name.” After thinking about it, he asked again: “Do you know what this paper will mean to you once it is published?”

Li Mo shook his head, because he was not interested in reputation, so normally Don’t care about these things either.

Professor Wu said solemnly: “The four-color conjecture is very different from the Koalas conjecture you completed last time. Although there is no distinction between high and low mathematical problems, the mathematical world is very realistic. Although conjecture is difficult, it is only an obscure topic. The four-color conjecture is different. It is very well-known all over the world, and our textbooks will have to be rewritten.”

He paused when he said that. After a while, he picked up the water glass and took another sip of water, and then slowly said: “Maybe you will become famous overnight because of this paper. After all, it is a four-color conjecture. To be honest, even I am jealous.”

Li Mo shook the head and said sternly: “Actually, I didn’t think about it that much. This paper is just an ordinary paper in my eyes.”

Looking at Li Mo for a while With the appearance of a vice nerd, Professor Wu sighed in his heart, maybe only such a pure person can solve the problems that the world cannot solve.
