Abstract

Let \(P_{k}\) and \(C_k\) respectively denote a path and a cycle on \(k\) vertices. In this paper we give necessary and sufficient conditions for the existence of \(\{P_{5}, C_4\}_{\{p, q\}}\)-decomposition of tensor product and cartesian product of complete graphs. Further we extent such decomposition to complete multipartite graphs.
