摘    要:设H是一个超图(图),对于它的一个k边着色c:E(H)→{1,2,∧k},我们记f(H,c)是由k种颜色中,由同一色类导出的子超图(子图)中所含分枝数最少的子超图(子图)的分枝数。fk(H)表示H中所有k边着色中f(H,c)的最大值,即fk(H)=maxf(H,c)。本文主要研究了路、Ti’、广义θ-图的成分着色,并得到了fi(Pn)=(n-1/k,f(Ti^*)=i-1/k]+1∫k(Gθ)=2

关 键 词:  Ti^*  广义θ-图  着色  分枝数

Abstract:Let H be a hypergraph or graph.For a k -edge coloring c:E(H)→{1,2,∧k},let f(H,c) be the number of components in the subhypergraph or subgraph induced by the color class with the least number of components.Let f_k(H) be the the maximum possible value of f(H,c) ranging over all k -edge colorings of H.In this paper we disscused edge -coloring of path,T_i~* and Generalized θ- Graph with many components,then we get the value of f_k(P_n) =(n-1)/k],f(T_i~*) =(i-1)/k]+1,f_k(G_θ) =2.
Keywords:T*i
