Lovász's perfect-matching conjecture for cubic vertex transitive graphs
Lovász's perfect-matching conjecture for cubic vertex transitive graphs
Let be a finite cubic vertex transitive graph, and let be a perfect matching in . Write for the graph obtained by deleting the edges of . Lovász's conjecture. There exists a perfect matching in such that consists either of one cycle, in which case is Hamiltonian, or of two disjoint cycles of the same length. If true, this would imply that all finite vertex transitive cubic graphs have a uniform partite presentation; the source describes the conjecture as still open.
