A pictorial proof of the Four Colour Theorem

General Mathematics 2021-10-20 v1

Abstract

We give a pictorial proof that transparently illustrates why four colours suffce to chromatically differentiate any set of contiguous, simply connected and bounded, planar spaces; by showing that there is no minimal planar map. We show, moreover, why the proof cannot be expressed within classical graph theory.
