报告摘要：It is conjectured by Berge and Fulkerson that every bridgeless cubic graph has six perfect matchings such that each edge is contained in exactly two of them. The Berge-Fulkerson Conjecture holds for 3-edge-colorable cubic graphs. A cubic graph is a snark if it is bridgeless and not 3-edge-colorable. In this talk, the Berge-Fulkerson conjecture is verified for some permutation graphs and an infinite family of cyclically 6-edge-connected snarks.
