摘 要: | 应用构造染色函数法研究了冠图C_m·C_n、C_m·C_n的邻点可区别V-全染色.通过对P_m·C_n的邻点可区别V-全染色的研究巧妙给出了C_m·C_n邻点可区别V-全染色,并得到了这些图的邻点可区别V-全色数,从而验证了图的邻点可区别V-全染色猜想.

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

Abstract: | 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. |
