Hopf–Galois structures on finite extensions with quasisimple Galois group

Name: Work Video:
Duration: 3 min 30 s
Description: Let $L/K$ be a finite Galois extension of fields with Galois group $G$. It is known that $L/K$ admits exactly two Hopf-Galois structures when $G$ is non-abelian simple. In this paper, we extend this result to the case when $G$ is quasisimple.
