Fan–Raspaud conjecture for bridgeless cubic graphs
Fan–Raspaud conjecture for bridgeless cubic graphs
Let be a bridgeless cubic graph. Fan–Raspaud conjecture. The graph contains three perfect matchings such that no edge is covered by all three of them. The Berge–Fulkerson conjecture implies this conjecture, but the Fan–Raspaud conjecture remains open, including in the finite setting discussed in the source.
