Wenjie Wang · Journal of Gansu Lianhe University · 2006
Let P_m be a path with in vetices and S_n be a star with ntl vertices.The join graph of P_m and S_n,deneted by P_mVS_n,is the graph obtained by connecting each vertes of P_m with each vertex of S_n.The edge chromatic number and total chromatic number of P_mVS_n are given in this paper.
