U S Rajput, Bal Govind Shukla . P9-factorization of Symmetric Complete Bipartite Digraph. International Journal of Computer Applications. 66, 17 ( March 2013), 14-21. DOI=10.5120/11175-6199
In path factorization, Ushio [1] gave the necessary and sufficient conditions for P_k-design when k is odd. P_2p -factorization of a complete bipartite graph for p an integer, was studied by Wang [2]. Further, Beiling [3] extended the work of Wang [2], and studied P_2k -factorization of complete bipartite multigraphs. For even value of k in P_k-factorization the spectrum problem is completely solved [1, 2, 3]. However, for odd value of k i. e. P_3,P_5,P_7,P_9 andP_(4k-1), the path factorization have been studied by a number of researchers [4, 5, 6, 7, 8]. The necessary and sufficient conditions for the existence of? P ??_3-factorization of symmetric complete bipartite digraph were given by Du B [9]. Earlier we have discussed the necessary and sufficient conditions for the existence of P ?_5 and P ?_7 -factorization of symmetric complete bipartite digraph [10, 11]. Now, in the present paper, we give the necessary and sufficient conditions for the existence of P ?_9-factorization of symmetric complete bipartite digraph, K_(m,n)^*.
