报告摘要: The graph is called s-arc-transitive digraph if its graph automorphism group acts transitive on its vertices and s-arcs. It is well known that the study of s-arc-transitive (di)graphs is a hot topic of algebraic graph theory. In particular, the classification and characterization of such graphs has been closely watched, which is recognized hard but of great theoretical. In this talk, we focus on research the describe and classification of s-arc-transtive (di)graphs. In particular, we will introduce some commonly methods and share with you our recent results on the classification of symmetry graphs.
