Hopf orders in $K [C_{p}^{3}]$ in characteristic $p$

Robert Underwood

Let $p$ be prime, let $K$ be a non-archimedean local field of characteristic $p$ and let $C_{p}^{3}$ denote the elementary abelian group of order $p^{3}$ . We give a complete classificati…

Hopf Forms and Hopf-Galois Theory

Timothy Kohl, Robert Underwood

Let $K$ be a finite field extension of $\Q$ and let $N$ be a finite group with automorphism group $F=\Aut(N)$. R. Haggenmüller and B. Pareigis have shown that there is a bijection…
