Adjacent Vertex-Distinguishing E-Total Coloring on the Multiple Join Graph of Complete Graph and Wheel
Abstract:
υυυLet G be a simple graph, k be a positive integer, f be a mapping from V(G)∪E(G) to {1,2,...,k} . If ∀uv∈E(G) , we have f(u)≠f(v) , f(u)≠f(uv),f(v)≠f(uv) , C(u)≠C(v), where C(u)={f(u)}∪{f(uv)|uv∈E(G)}. Then f is called the adjacent vertex distinguishing E-total coloring of G. The number is called the adjacent vertex –distinguishing E-total chromatic number of χSubscript text(G)=min{k|G has a k-AVDETC} . The adjacent vertex distinguishing E-total chromatic numbers of the multiple join graph of wheel and complete graph are obtained in this paper.
