【摘要】 对于正整数m,n∈N+(N+为正整数集合),设Kn表示n个顶点的完全图。本文给出一类图(K2Vkn)·(K2 V km),同时,论证了当m=n-1(n≥2)时,该图是协调图。更多还原

【Abstract】 In this paper,for natural numbers m, n∈ N+. Let Kn is a n - verex complete graph, kn is complementary graph of graph k’n, (K2 V kn) is join graph of K2 and kn .This paper has given one kind of graph(K2 V kn) · (K2 V km) ,proves that the one kinds graph is harmonious graph when m = n -1(n≥2).更多还原
