Factorizations of the product of cycles

An H-factorization of a graph G is a partition of the edge set of G into spanning subgraphs (or factors) each of whose components are isomorphic to a graph H. Let G be the Cartesian product of the cycles C1,C2,…,Cnwith |Ci|=2ki≥4 for each i. El-Zanati and Eynden proved that G has a C-factorization,...
