    A proper total-coloring is called vertex-distinguishing total-coloring if the color sets of different vertex and its incident edge are different.The minimum number of colors of a vertex-distinguishing total-coloring is called the vertex-distinguishing total chromatic numbers of the graph.In this paper,the vertex-distinguishing total chromatic numbers of Sm□Sn,Sm□Fnand Fm□Fnare given.

    Coloring problem is a classical difficult problem of graph theory. It is a fundamental problem in scientific computation and engineering design. In recent years, a variety of graph coloring problems frequently appeared and solved many problems in production. It is a difficult problem to discuss the chromatic number of a given graph class. In the paper, we introduce several kinds of chromatic numbers of graphs such as adjacent-vertex-distinguishing total chromatic number, adjacent-vertex-distinguishing proper edge chromatic number, smarandachely-adjacent-vertex-distinguishing edge chromatic number, and the multi-fan graphs are considered.

    A proper total coloring of the graph G is called vertex-distinguishing total coloring,if any two vertices have different color sets,where the color set of a vertex is the set composed of all colors of the vertex and the edges incident to it.On the base of the bound of vertex-distinguishing total chromatic number(χvt(G)≤|V(G)|+2).The new upper bound of vertex-distinguishing total chromatic number is obtained by way of probability.

    Let G be a simple connected graph with ordr not less than 3,k-proper edge coloring of G is called adjacent-vertex distinguishing,if for arbitrary two adjacent vertices which are incident to different sets of colored edges.The minimum number required for an adjacent-vertex distinguishing edge coloring(AVDEC) of G is called the adjacent strong edge chromatic number.In this paper,we give two upper bounds of adjacent-vertex distinguishing edge chromatic number of Cartesian product graphs,and some results are obtained.
