Reward! ! ! Four-color problems in the three major mathematical problems in the world —— Mr. Zhou Lijing offered a reward of 200,000 yuan to find a counterexample.

The three major mathematical conjectures in the world are Fermat conjecture, four-color conjecture and Goldbach conjecture. The similarity of these three problems lies in their simple topics and profound connotations, which have influenced mathematicians from generation to generation. Among them, the logical argument of the four-color puzzle has not been proved. Just recently, Mr. Zhou Lijing, a mathematician in Jinyun, Lishui, Zhejiang Province, proved the four-color theorem of maps by logical methods, and offered a reward of 200,000 yuan to find people who can prove counterexamples by using the logical methods of the four-color theorem he published, or find out the flaws in the paper that are enough to overthrow those who proved invalid and those who used their authority to identify them as effective.

Just last June165438+1October, Mr. Zhou Lijing's paper "Proving the World's Mathematical Puzzle-Four-color Map Puzzle by Mathematical Physics Method" was published in Inner Mongolia Science and Technology (No.2019 12 /vol. 38/450). After the paper was published, it received rave reviews and congratulations, but it also received many questions and puzzles. Especially those who are so-called in power and above themselves think that this is a farce, a joke of Jinyun people, a scandal and a folk science. Good-hearted people think they have been fooled and should start crisis public relations to prevent the scandal from expanding. But I thought, did I really fall for it? Fooling is also me fooling others. I made a paper and published it in a magazine, which fooled people all over China and even the world. How great it is to fool people all over the world. I am a citizen. Why? I am a citizen. I'm very proud. I am a citizen. I don't spend money for my country. I am also a scientist. Many accomplished mathematicians are themselves so-called folk disciplines. Is China great? He used to be a shop assistant. Is Fermat in France great? He is a lawyer. In foreign countries, full-time people are called in-hospital and amateur people are called out-of-hospital. In China, people outside hospitals are called people's subjects, which is the antonym of science. In fact, most inventions are made by the so-called people. People's science is really great. But it has been a pity that it was not published in first-class international journals. I hope to return to the paper itself for discussion and demonstration. I hope that all major math enthusiasts, experts and professors will discuss the proof and discussion of this logical method together.

Zhou Lijing, born in Jinyun, Lishui, 1962, bachelor of science, senior engineer. 1979 was admitted to the physics department of Hangzhou university with full marks in physics. Now he is the chairman of Zhejiang Boxing Electronics Co., Ltd., and his research direction is the design and manufacture of high-power semiconductor chips and devices. His greatest hobbies are number theory research and four-color research, which took him 40 years of hard work and became his most persistent pursuit in his life.

According to Zhou Lijing, although he studied physics, mathematics was his interest. After studying the world's three major mathematical conjectures in college, he became interested in the problem of four-color maps, but at that time he spent a lot of time using various methods to no avail. In the next 40 years, he never gave up, continued to cling to the logical argument of the four-color conjecture, and constantly explored and skillfully integrated physical methods into the argument, and finally ushered in a major breakthrough in research and argumentation.

Zhou Lijing's original creation: transforming the four-color problem into a special plane structure, and adding one-dimensional and three-dimensional physical methods to solve any two-dimensional arbitrary plane structure problem, skillfully proved the four-color problem. Firstly, the change rules are created according to the map source, and then the conclusion of the influence on the results is deduced through the change of the rules. It is clear and simple to use the conclusion to guide the operation of specific color filling sequence. It uses mathematical and physical methods to make complex things simple and clear. In particular, he went back to check the sufficiency of various hypothetical degrees of freedom to deduce the arbitrariness of the map, and proved that any complex map can be colored differently in any adjacent area with four colors (no enclaves). Not only prove it theoretically, but also make a specific color filling order and method for any example. The evidence should be very sufficient and specific.

The four-color problem, also known as four-color conjecture and four-color theorem, is one of the three major mathematical conjectures in the world. It was first put forward by a British college student in Goudry in 1852. The content of the four-color problem is "any map with only four colors can make countries with the same border have different colors." In other words, a map only needs four colors to mark it, which will not cause confusion. Expressed in mathematical language, it means "divide the plane into non-overlapping areas at will, and each area can always be marked with one of the four numbers 1234, without making two adjacent areas get the same number." The contiguous zone mentioned here means that there is a whole section of boundary that is common. If two regions intersect at only one point, they are not adjacent. Because coloring with the same color will not cause confusion.

After the four-color problem was put forward, it was repeatedly proved and denied by many mathematicians, which was unexpected and extremely difficult. Although many mathematicians have racked their brains for this, they have never found anything. The most recent proof was made by American mathematicians Appel and Harken in 1976 with the help of computers, hence the name four-color theorem. But this is only proved by computer method. Mr Zhou Lijing has completed its logical method proof.
