The four-color theorem states that any map in a plane can be colored using four-colors in such a way that regions sharing a common boundary (other than a single point) do not share the same color. This problem is sometimes also called Guthrie's problem a
Set up when the plane graph e=n is n=4 and v=3 (E-2) Then Kn satisfies the four colour theorem Add methods are as follows: A. In blank 3 corners, add figure (1) B. Add on the line, as shown in figure (two) C. Add to figure outside, as shown in figure (three) ...

The four color theorem in Coq The four-colour theorem, that every loopless planar graph admits a vertex-colouring with at most four different colours, was proved in 1976 by Appel and Haken, using a computer. Here we give another proof, still using a computer, but sim... G Gonthier 被引...
THE correctness of the statement that any plane map may always be tinted with four colours in such a way that two areas meeting on the same boundary never have the same colour has always been admitted since M枚bius mentioned it in 1840, although no mathematical proof of this theorem has ...
