    Abstract

    Abstract. Let Pk+1 denote a path of length k and let C k denote a cycle of length k. As usual Kn denotes the complete graph on n vertices. In this paper we investigate decompositions of Kn into paths and cycles, and give some necessary and/or sufficient conditions for such a decomposition to exist. Besides, we obtain a necessary and sufficient condition for decomposing Kn into p copies of P 5 and q copies of C4 for all possible values of p ≥ 0 and q ≥ 0.
