    Multipartite graph decomposition: cycles and closed trails

    Get PDF
    This paper surveys results on cycle decompositions of complete multipartite graphs (where the parts are not all of size 1, so the graph is not K_n ), in the case that the cycle lengths are “small”. Cycles up to length n are considered, when the complete multipartite graph has n parts, but not hamilton cycles. Properties which the decompositions may have, such as being gregarious, are also mentioned

    In this paper we consider the uniformly resolvable decompositions of the complete graph KvK_v minus a 1-factor (KvI)(K_v − I) into subgraphs where each resolution class contains only blocks isomorphic to the same graph. We completely determine the spectrum for the case in which all the resolution classes consist of either 4-cycles or 3-stars
