摘    要:G(V,E)是一个简单图,忌是一个正整数,f是一个V(G)∪E(G)到{1,2,…,k}的映射.如果任意uv∈E(G),则f(u)≠f(v),f(u)≠f(uv),f(v)≠f(uv),C(u)≠C(v),称,是图G的邻点可区别E-全染色,称最小的数k为图G的邻点可区别E-全色数.本文给出了扇与星、路、圈间的多重联图的邻点可区别E-全色数.其中C(u)={f(u)}∪{f(uv)|uv∈E(G)}.

关 键 词:多重联图  邻点可区别E-全染色  邻点可区别E-全色数

Abstract:Let G(V,E) be a simple graph,k be a positive integer,f be a mapping from V(G) ∪E(G) to {1, 2,…,k}. If arbitary uv∈E(G),we have f(u)≠f(v),f(u)≠f(uv),f(v)≠f(uv),C(u)≠C(v). Then f is called the adjacent vertex-distinguishing E-number of G. The minimal number or k is called the adjacent vertex-distinguishing E-total chromatic number of G. The adjacent vertex-distinguishing E-total chromatic number of the multiple join graph of fan, star,path and cycle is obtained in the paper,where C(u)= {f(u)} ∪ {f (uv) | uv∈ E(G) }.
Keywords:multiple join graph  adjacent vertex-distinguishing E-total coloring  adjacent vertex-distinguishing E-total chromatic number
