地图颜色定理的重新表述

Reformulating the Map Color Theorem

Louis H. Kauffman

摘要:

本文讨论了平面地图四色着色问题的一种新的形式。背景是三次图的三种颜色的边着色,使得每个顶点处出现三种不同的颜色。我们讨论了Eliahou-Kryuchkov猜想、Penrose公式、向量向量积公式以及由G.斯宾塞-布朗后者包括Spencer-Brown奇偶引理的证明和奇偶通算法的讨论。

英文摘要:

This paper discusses reformulations of the problem of coloring plane maps with four colors. The context is the edge-coloring with three colors of cubic graphs such that three distinct colors occur at each vertex. We include discussion of the Eliahou-Kryuchkov conjecture, the Penrose formula, the vector cross product formulation and the reformulations in terms of formations and factorizations due to G. Spencer-Brown. The latter includes a proof of the Spencer-Brown parity lemma and discussion of the parity-pass algorithm.
