报告摘要:A graph is said to be stable if its canonical double cover has no unexpected symmetries. Graph stability has been studied in the literature from different viewpoints. In this talk I'll first review these viewpoints and then focus on the stability of circulant graphs. In particular, I'll give an answer to a question of Wilson in 2008 on the stability of arc-transitive circulant graphs and infinitely many counterexamples to a conjecture of Marusic, Scapellato and Zagaglia Salvi in 1989. This is joint work with Yan-Li Qin and Sanming Zhou..
