Do you know four color theorem? - Zombie Land Saga~Konno Junko - 3D model by snegi5566 (@snegi5566) [f6c8d42]I published a proof of the four color theorem in 2016 year, I think that professional and none-professional mathematicians could understand and verify it . I am very happy if my proof of the four color theorem by induction is properly veri ed and recognized before I publish the short proof of Flt.Thanh you! References

Nov 07, 2002 · After hundreds of years the 4-Color theorem was proved; but the proof involved breaking the problem down into thousands of cases, then verifying each of them by computer. Though you would expect them to applaud the solution of an age-old, challenging problem, mathematicians reacted coolly to the announcement of the proof.

W HY are the 1800s called the “nineteenth century?” Why are the 1900s called the “twentieth century?” The answer is a fundamental mistake that was made, very early in the history of mathematics, in deciding how to number things.

Coloring (The Four Color Theorem) This activity is about coloring, but don't think it's just kid's stuff. This investigation will lead to one of the most famous theorems of mathematics and some very interesting results.

The four color theorem was proven in 1976 by Kenneth Appel and Wolfgang Haken. It was the first major theorem to be proved using a computer. Appel and Haken's approach started by showing that there is a particular set of 1,936 maps, each of which cannot be part of a smallest-sized counterexample to the four color theorem.There are meaningful generalizations, if you consider surfaces like sphere, torus, Möbius band etc. as "3D objects". The minimum number of required colors for the mentioned surfaces is 4, 7 and 6, respectively.
