Adjacent Vertex-distinguishing V-total Coloring of Several Categories of Corona Graphs

In this paper,the adjacent vertex-distinguishing V-total coloring of C_m ? P_n and P_m ·C_n are obtained by constructing coloring function.Through the adjacent vertexdistinguishing V-total coloring of P_m ? C_n,we skilfully get the adjacent vertex-distinguishing V-total coloring of C_m·C_n,and obtain the adjacent vertex-distinguishing V-total chromatic number of those graphs.Further,the conjecture of adjacent vertex-distinguishing V-total coloring of graphs is checked.
