Equitable vertex arboricity of outer-1-planar graphs
摘要
Abstract
An equitable tree-k-coloring is a vertex k-coloring.The sizes of any two color classes differ by at most 1,and the subgraph induced by any color class is a forest.The minimum integer k that a graph G admits an equitable tree-k-coloring is the equitable vertex arboricity of G.It is proven that the equitable vertex arboricity of every outer-1-planar graph is at most 3,and then the equitable vertex arboricity conjecture is verified for outer-1-planar graphs.关键词
