Asymptotical results on the automorphism groups of canonical double cover of graphs

Bartłomiej Bychawski, Ademir Hujdurović, Đorđe Mitrović +1

The canonical double cover $BX$ of a graph $X$ is the direct product $X\times K_2$. A graph $X$ is stable if every automorphism of $BX$ is induced by automorphisms of $X$ and $K_2$…
