Sunlet factors for Cartesian products of cycles
Abstract
A sunlet is a cycle with a pendant edge attached at each vertex of the cycle. For the bipartite toroidal grid graphs C2n C2n, factorizations into sunlets are given by homomorphisms from disjoint unions of s copies of a sunlet for s ∈ \1, n, n2\, n ≥ 3 such that edges are mapped bijectively.
