Stability of circulant graphs
Seminar/Forum
A graph is said to be stable if its canonical double cover has no unexpected symmetries. Graph stability has been studied extensively in the literature from different viewpoints. In this talk I will first review these viewpoints and then focus on the stability of circulant graphs. In particular, I will give an answer to a question of Wilson on the stability of arctransitive circulant graphs and infinitely many counterexamples to a conjecture of Marusic, Scapellato and Zagaglia Salvi in 1989.
