摘要
对于图G(V,E)的正常k-全染色φ称为G(V,E)的k-均匀全染色,当且仅当任意两个色类中的元素总数至多相差1.xvee(G)=m in{k存在图G的一个k-均匀全染色}称为G的均匀全色数.本文得到了两类M ycielsk i图及圈,轮图和扇形的均匀全色数.
A proper k-total coloring cpof G(V, E) is said to be a k-equitable total coloring of graph G(V, E), iff the number of vertices and edges in any two color classes differ by at most one and let xe^vt(G)=min{k |G has a k-equitable total coloring} is called the equitable total chromatic number of G. This paper present some results about the equitable total chromatic number of two classes of Mycielski graph and some special planar graph.
