Hopf-Galois Realizability of $Z_{n} ⋊ Z_{2}$

Namrata Arvind, Saikat Panja

Let $G$ and $N$ be finite groups of order $2 n$ where $n$ is odd. We say the pair $(G, N)$ is Hopf-Galois realizable if $G$ is a regular subgroup of $\h(N)=N\rtimes\au(N)$. In this a…

On $Z_{N} ⋊ Z_{2}$ -Hopf-Galois structures

Namrata Arvind, Saikat Panja

Let $K / F$ be a finite Galois extension of fields with $G a l (K / F) = Γ$ . In an earlier work of Timothy Kohl, the author enumerated dihedral Hopf-Galois structures acting on dihedral ext…

Unit group of $\f_{p^k}\SL(3,2),p\geq 11$

Namrata Arvind, Saikat Panja

We provide the structure of the unit group of $\f_{p^k}(\SL(3,2))$, where $p \geq 11$ is a prime and $\SL(3,2)$ denotes the $3 \times 3$ invertible matrices over $\f_2$.
