提出图的星边星-全染色的概念,图G的一个正常全染色被称为星边星-全染色,如果对G中点进行星染色,边进行星边染色.并定义图的星边星-全色数,记为χsTs(G).用构造染色的方法给出一些特殊图(路,圈,轮,扇,完全图)的星边星-全色数.同时运用概率方法给出满足一定条件的图G的星边星-全色数的一个上界,即若图G的最大度Δ(G)≥30,则χsTs(G)≤24(Δ-1)3/2.
A concept of star-edge-star total coloring of graphs was presented.A proper total coloring of a graph G would be called star-edge-star total coloring if its vertices were star coloring and its edges were star-edge coloring.The star-edge-star total chromatic number of G was defined and denoted by χTss(G).The star-edge-star total chromatic number of some particular graphs(path,cycle,wheel,fan,complete graph) were given by using the method of coloring construction.Meantime,an upper bound of star-edge-star total chromatic number of graph which satisfied definite conditions,was given by means of probabilistic method,namely χTss(G)≤24(Δ-1)3/2 for a graph G if its maximum degree Δ(G)≥30.
