摘要:

如果一个图$\varGamma$存在半正则自同构群$H$,且$H$作用在图$\varGamma$的点集上有两个相同长度的轨道,那么称图$\varGamma$为群$H$上的双凯莱图。双凯莱图的对称性的研究是代数图论中重要的研究课题。利用三度四循环图的结构,对半二面体群上三度连通边传递的双凯莱图进行了研究,给出了这类双凯莱图的完全分类。

Abstract:

A graph is said to be a Bi-Cayley graph over a group $H$ if it admits $H$ as a semiregular automorphism group with two vertex-orbits. The study about the symmetry of  Bi-Cayley graph is an important topic in algebra graph. Using the structure of the cubic tetracirculant graph,  we study cubic connected edge-transitive bi-Cayley graphs over semidihedral groups  and give  a classification of this kind of graphs.

Key words: bi-Cayley graph, edge-transitive, Cayley graph, arc-transitive, semidihedral group
