报告摘要:
A graph admitting a group H of automorphisms acting semi-regularly on the vertices with exactly two orbits is called a bi-Cayley graph over H. This generalisation of a Cayley graph gives a class of graphs that includes many important examples such as the Petersen graph, the Gray graph and the Hoffman-Singleton graph, and most of the known examples are actually edge-transitive. In this talk, I shall introduce some of our recent work regarding edge-transitive bi-Cayley graphs.
