Liu Fang once wrote a new operating system, which is small in size but very powerful, which means that he has a high degree of attainment in the relevance of programs. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

However, this is far from enough, in Liu Fang's view, the program is not the smaller the better, but the more concise the better, without affecting the function, the program is the most simplified, which is the ultimate embodiment of the program.

The so-called three-dimensional refers to the logical structure of the program through countless kinds of correlations, which is the correct solution of three-dimensionalization.

"It's a pity that I don't have a computer, I can't do practical verification, well, let's read books to supplement knowledge first, if you don't learn mathematics well, it is impossible to complete this idea."

Liu Fang sighed, and then continued to read carefully. Liu Fang already had an unsatisfactory idea about the operating system he had written before, and his knowledge accumulation was not enough at that time, so there were still great limitations, and the program he wrote was certainly not the best.

Now that he has been exposed to advanced mathematics, his thinking has been greatly broadened, and his ideas will naturally change.

Not long after reading it, Liu Fang picked up the pen and paper and got busy, the content that can make him write is definitely not ordinary content, otherwise his memory is so powerful, he still needs to take notes?

"It's an interesting idea, well, I'll look into it first."

"This doesn't seem to work, we have to change the way......"

"This won't work, well, will it work this way?"

Liu Fang soon entered a state of self-forgetfulness, not noticing the passage of time at all.

At noon, Xiao Yang went out for a trip, and soon she walked in again, only to see her holding two lunch boxes, because after a while, she put one of the lunch boxes on the table, and then walked towards the bookshelf with the other lunch box.

Liu Fang was concentrating on mathematical argumentation, and he didn't notice it until Xiao Yang walked to a place less than three meters away from him.

Liu Fang looked up, and then wondered: "Sister Administrator, ...... are you?" ”

Xiao Yang looked at Liu Fang's handsome cheeks, his little face was hot for no reason, and he said embarrassedly: "That...... I saw that you didn't go out to eat at noon, and it happened that the aunt in the cafeteria had too much food for me, and I couldn't finish it, and it was too wasteful to throw it away, so I wanted to ask you if you ate it? ”

When Liu Fang heard that there was such a good thing, he immediately smiled and said: "This relationship is good, thank you Sister Administrator!" ”

Xiao Yang handed the lunch box to Liu Fang, and when she saw Liu Fang laying a torn sheet in the corner of the wall, she couldn't help asking, "Why don't you go to the desk outside to read?" ”

Liu Fang covered up while eating: "I don't like a lot of people, it's good to stay quietly in the corner alone." ”

"Oh, then you can eat, remember to throw the lunch box in the trash when you are done."

"Okay sister, I see."

Xiao Yang returned to her position, opened the lunch box and ate, her eyes always glanced at the direction where Liu Fang was, but because it was blocked by the bookshelf, she couldn't see Liu Fang at all.

Xiao Yang said in his heart: I forgot to ask his name just now, alas, I am really not angry, why can't I speak when I see his face? By the way, I saw him taking notes and holding a math book in his hand, could it be that he is also a math student? But how come I've never seen him?

Liu Fang quickly finished his lunch, threw the lunch box into the trash can at the door, and then returned to the corner to continue his work until the library closed.

Xiao Yang is a very competent successor administrator, and after the people who read the books are gone, she starts cleaning according to Aunt Wang's instructions.

"Fortunately, I caught up with the trip, Yang Wei, are you in there?"

When Xiao Yang was mopping the floor, he heard Mr. Li's voice. Teacher Li has great prestige in the Department of Mathematics of Kaijiang University, Yang Wei admires him very much, hearing Teacher Li's question, Yang Wei hurriedly replied: "Teacher Li, it's me, ...... are you?" ”

Teacher Li walked into the library with a smile and said to Yang Wei, "I am doing mathematical research and want to borrow a book. ”

"Oh, you can borrow whatever book you want."

"Okay, I'll register myself when I go out."

Teacher Li smiled and walked to the bookshelf of advanced mathematics and began to look for his goal.

It didn't take long for him to pick up a book on three-dimensional geometry analysis, and after registering, Mr. Li left satisfied.

Just like last night, Mr. Li took a shower after returning to the teacher's dormitory, and then sat down at his desk to study, but as soon as he opened the book, a piece of paper fell out of the book.

Mr. Li also thought that this piece of paper was a bookmark that someone put in after reading the book, because most of the content of the book is not too profound, so Mr. Li was not too surprised by this, he put this piece of paper aside, and was ready to wait for himself to return the book, and then stuff it back into the page, which can be regarded as returning to its original owner.

Then Mr. Li began to look through it, and while reading, he thought about it against the book "Topology" that he borrowed yesterday.

Unconsciously, the time came to three o'clock in the morning, Mr. Li yawned, he put down the book, and stretched: "I'm so tired...... This book of "Topology" is really too difficult, I have been thinking about it for so long in combination with other knowledge, and I still have no clue......"

When Mr. Li was stretching, he accidentally knocked the books on the table down, and he hurriedly reached out to pick them up.

When he picked up a piece of paper, he glanced at it casually, and then he was stunned: "It turns out that this is a geometric formula, I thought someone scribbled it, huh?" This...... This ......"

Mr. Li looked at it twice out of curiosity, but his eyes widened wider and wider, and his gaze was fixed on this piece of paper, and he couldn't move it anymore.

This seems to be the process of argumentation of Poincaré's conjecture...... What the hell am I? How else could there be such a thing in the school library? ”

Mr. Li still had a little impression of this paper, which was sandwiched in the three-dimensional geometry analysis book he borrowed before, and he thought it was someone's graffiti work at the time, but he didn't look at it closely. Looking closer now, he couldn't help but have a feeling of extreme shock and absurdity.

Mr. Li, the mathematics level of Kaijiang University, knows very well that if he thinks he is second, then no one dares to say that he is the first, but what is going on now? Why is there a piece of paper in the book I borrowed that confirms Poincaré's conjecture?

Although Mr. Li is not capable of solving the Poincaré conjecture, as a senior mathematics professor, he still has some research on this world-wide mathematical problem, and his inability to solve this problem does not mean that he cannot understand the methods of others to solve this problem.
