Abstract: Berge [3]在1976年,曾經發表一些有關多重著色問題的研究。在本文中,我們研究乘積與合成圖形的多重著色的性質。我們證明了若G是具有偶數個頂點的第一類圖形[5],則G的多重色彩指數與其色彩指數相同。我們並證明若G1,G2都是可以多重著色的圖形,則G1×G2與G1 [G2] 也都是可以多重著色。
Berge [3] has studied some properties of multicoloring in a graph. In this pqper, we study the multicoloring in the product and composition of graphs. We show that if G has even vertices with the first class [5] , then the multicoloring index of G is equal to the chromatic index of G. We also show that if G1 and G2 are both multicolorable, then G1 × G2 and G1[G2] are also multicolorable.
