Abstract (in Japanese) (See Japanese page) 
(in English) The relation of channel assignment problems in wireless communications and coloring problems of graph theory is well-known. A channel in the wireless communication is corresponding to a color assigned to a vertex (an edge) in a graph. It is popular to minimize the number of colors assigned to vertices of the graph. However, the maximum number of colors called Grundy Number is also important. In the previous study, we show the upper bounds of colors assigned to some graphs. In the previous paper, we showed the realization of Grundy number on minimizing the number of vertices or edges of graphs. The authors also defined matching coloring, which is one of edge coloring, and show the relationship with channel assignment in wireless communication. In this paper, we discuss the properties of Grundy Coloring in matching coloring and the realization of Grundy Number.
