摘要

A graph S\Gamma$ is called a {lem bicirculant}if its automorphism group $\Aut(Gamma)$ contains a cyclic subgroup that acts semiregularly on the vertex set $V(Gamma)$ with two orbits. The study of circulants has attracted considerable attention in the literature, leading to a rich theory and numerous classification results. In this talk,I will introduce our recent work on a classification of locally primitive bicirculants.
