报告摘要:
Let be a graph and a nonnegative integer. Suppose is a mapping from to the vertex set of . If, for any vertex of , the number of neighbors of with is less than or equal to , then is called a -relaxed -coloring of . And is said to be -colorable. The -relaxed chromatic number of , denote by , is defined as the minimum integer such that is -colorable. In this talk, we discuss the -relaxed chromatic numbers of some special classes of graphs.
