WebBesides, decompositions of graphs into k-stars have also attracted a fair share of interest (see [9,25,39,41,43,44]). Moreover, decompositions of graphs into k-cycles have been a popular topic of research in graph theory (see [10,27] for surveys of this topic). The study of the {G,H}-decomposition was introduced by Abueida and Daven in [1]. WebIt is known that whenever υ(υ-1) ≡ 0 (mod 2m) and υ≥2m, the complete graph K υ can be decomposed into edge disjoint, m-stars [1,2].
