Chapter 144 Odd Perfect Conjecture

Li Mo has been immersed in the history told by the big head Pajeluian for a long time, didn’t expect The dominating Gould beast was so dramatically wiped out by the Pajeluian.

“New task released”, the learning system beeps.

Mission: Boy, let’s make persistent efforts.

Description: If you don’t take a small step, you can’t go a thousand miles. Without the accumulation of small currents, there can be no rivers and seas. Do not slack off in learning.

Requirement: Solve an unsolved math problem.

Reward: 200,000 subject experience points, one ordinary lottery.

Time limit: 30 days

Accept: Yes/No

This task needs to solve an unsolved math problem, Li Mo accepted it “happily” Yes, he has cracked two, and he has a lot of experience.

Li Mo, who returned to Yanda University, did not receive flowers or applause. No one even knows what he has done, but his heart is full of joy because he saved a person’s life, which is the biggest compliment to Li Mo.

Department of Mathematics, Professor Wu’s Office

Li Mo took the initiative to pour a cup of tea for Professor Wu, “teacher, I have been busy some time ago and neglected the study of mathematics, I’ll make a review for you here.”

This kid, Professor Wu looked at his behavior and wanted to be angry but couldn’t find a reason. He knew that Li Mo must have carried out an extremely important biological experiment, and he heard that a student in the Department of Biology who was in the late stage of ALS could go to school with a cane every day. I’m afraid it’s not his student’s masterpiece, but Li Mo doesn’t want to say it, so he doesn’t ask, he just needs to be a little more tolerant of such talented students.

Professor Wu said with a smile: “Okay, okay, now that you have completed the biological experiment, it’s time to turn your attention to mathematics.”

Li Mo The second time I came here, I wanted to choose a branch of mathematics as the research object.

He replied: “Of course, as a graduate student in the Department of Mathematics, I should have made achievements in mathematics.”

Professor Wu was very satisfied with his attitude and tasted The tea served by his disciple, looked at the jade green tea leaves hovering in the cup, and asked kindly: “Then which topic do you want to choose as your research object?”

“No Do you know that the teacher has heard of the odd perfect conjecture?” Li Mo asked mysteriously.

“You” Professor Wu suddenly felt that the tea in his mouth was so hot that he almost spit it out.

“Are you going to study the odd perfect conjecture?” Professor Wu still slowed down, fortunately he didn’t lose face in front of the students. But the subject proposed by his student was astonishing.

The odd perfect conjecture is a conjecture with a history of thousands of years. Its specific description is whether there is an odd perfect number in the natural numbers. A perfect number is a perfect number (must be a natural number) that is equal to itself if you add all of its factors except itself. For example, 6 is a perfect number. Since 6=1×6=2×3, in addition to itself, 6 has its divisors 1, 2, and 3. It can be seen that the sum of these three divisors is 1+2+3=6, which is exactly equal to 6 itself. In addition to 6, there are 28, 496, 8128…all perfect numbers.

By enumeration, we can see that all perfect numbers are even. So is there such an odd number that makes itself a perfect number?

This conjecture looks simple, but countless mathematicians have fallen at its feet. Euler, Euclid, Descartes, Nico Matthews have all studied this question, but have not got a clear answer.

So Professor Wu was really surprised that his students would choose to crack such a “stinky and hard” conjecture as a research topic. This problem is extremely difficult and not to mention, it is not the frontier field of current mathematical research. Now many talented mathematics graduate students take group theory and topology as their own research topics, so that even if the research fails, they can write several papers.

Professor Wu looked at Li Mo’s clear eyes, hesitated and said, “Why don’t you think about it again? This conjecture has not been proven for thousands of years, and it is too difficult.”

Li Mo knew the teacher’s good intentions. He looked at the sunlight penetrating the window and said, “Isn’t mathematics all about retreating when faced with difficulties, and I like numbers very much. Numbers are the foundation of mathematics.”

For his students, Professor Wu felt powerless for the first time. He began to miss those “stupid” students who would follow their own words as dogma.

He had nodded to say: “The perfect odd number conjecture has been studied by many well-known mathematicians in history. You can avoid many pitfalls by referring to their proof ideas.” For this kind of difficult conjecture, Professor Wu It is also beyond our reach, and can only provide some empirical references.

Li Mop nodded, “I will never forget what happened in the past, and I will be the teacher of what happened in the future. I will study the results of my predecessors first.”

After the conversation, Li Mo got up and left, Wu The professor looked at the back of him leaving, and said in his heart, “It’s also a trouble to have such an excellent student, and I feel like there is almost no knowledge to teach him.”

“No, I don’t seem to teach anything. Pass him!” Professor Wu patted his head.

The campus is still as quiet as ever, and the students in small groups walk along the road together, talking and laughing. On the sports field, some students even let out the wind, and there was a warm scene everywhere. After nearly a month of running around, Li Mo feels that he still prefers school life.

“Boss, are you back? Let’s have dinner now.” Xia Qing was cooking in the dormitory, and when Li Mo came back, she put the food on the table.

Now Xia Qing doesn’t have to follow him all day, because under Li Mo’s strong protest, they reached a three-part contract: “1. Xia Qing can’t follow Li Mo all day on campus. 2. Xia Qing has the right to protect Li Mo after leaving the campus. 3. Xia Qing has the right to amend the first article at any time.”

Compared with the complicated situation outside the campus, Yan Da is much safer inside. After Li Mo’s firm protest and approval from the Security Bureau, Xia Qing decided to “free-range” Li Mo in the school.

Xia Qing, who is in her spare time, will go to the music department to take classes during the day. She has liked music since she was a child, and even wanted to be a musician at one time, but she had no conditions at that time. Now that she is staying in Yanda, she will naturally not miss this good opportunity. And Yanda’s teacher doesn’t mind the “extra” students. In the evening, Xia Qing will come back early to prepare dinner for the two.

“You taste so good in roasting eggplant.” Li Mo sat at the dining table and tasted a bite of the dish. Although Xia Qing’s temper was not good, she cooked well.

After dinner, Xia Qing will take a walk along the lake, while Li Mo “hides” in his room and starts to study “odd perfect conjectures”.
