Negating Four Color Theorem with Neutrosophy and Quad-stage Method
Keywords:The four color theorem, neutrosophy,, quad-stage,, boundary, proof for negation, the two color theorem, the five color theorem.
With the help of Neutrosophy and Quad-stage Method, the proof for negation of “the four color theo-rem” is given. In which the key issue is to consider the color of the boundary, thus “the two color theorem” and “the five color theorem” are derived to replace "the four color theorem"
