Automatic realization of Hopf Galois structures

Teresa Crespo

We consider Hopf Galois structures on a separable field extension $L / K$ of degree $p^{n}$ , for $p$ an odd prime number, $n \geq 3$ . For $p > n$ , we prove that $L / K$ has at most one ab…

Hopf Galois structures on extensions of degree twice an odd prime square and their associated left braces

Teresa Crespo

We determine the Hopf Galois structures on a Galois field extension of degree twice an odd prime square and classify the corresponding left braces. Besides we determine the separab…

Computation of Hopf Galois structures on separable extensions and classification of those for degree twice an odd prime power

Teresa Crespo, Marta Salguero

A Hopf Galois structure on a finite field extension $L / K$ is a pair $(H, μ)$ , where $H$ is a finite cocommutative $K$ -Hopf algebra and $μ$ a Hopf action. In this paper we present a…
