Abstract:For every graph G, let View the MathML source. The main result of the paper says that every n-vertex graph G with View the MathML source contains each spanning subgraph H all whose components are isomorphic to graphs in View the MathML source. This generalizes the earlier results of Justesen, Enomoto, and Wang, and is a step towards an Ore-type analogue of the Bollobás-Eldridge-Catlin Conjecture.
Keywords:Packing   Degree conditions
