WebJul 7, 2024 · Theorem 15.3. 3. The problem of 4 -colouring a planar graph is equivalent to the problem of 3 -edge-colouring a cubic graph that has no bridges. This theorem was proven by Tait in 1880; he thought that every cubic graph with no bridges must be 3 -edge-colourable, and thus that he had proven the Four Colour Theorem. WebColour Theorem,” Quarterly Journal of Mathematics, 24, 332–38 (1890) (partially reprinted in Graph Theory: 1736-1936) states: “The present article does not profess to give a proof of [The Four-Colour Theorem]; in fact its aims are so far rather destructive then constructive, for it will be shown that there is a defect in the now
