图D_(m,4)的[r,s,t]-着色

[r,s,t]-Colouring of Graph D_(m,4)

由m个四回路恰有一个公共点构成的图记为Dm,4。研究图Dm,4的点着色、边着色和全着色,给出图Dm,4在参数r,s,t满足一定条件时的[r,s,t]-色数。

Let a graph contains m cycles C4 of lengths 4 have a common vertex,then we denote this graph as Dm,4.Then we study the vertex coloring,edge coloring and total coloring of Graph Dm,4,and give the [r,s,t]-chromatic numbers of the Graph Dm,4 when the parameters r,s,and t meet certain conditions.
