Finite skew braces with isomorphic non-abelian characteristically simple additive and circle groups

Cindy Tsang

A skew brace is a triplet $(A, \cdot, \circ)$ , where $(A, \cdot)$ and $(A, \circ)$ are groups such that the brace relation $x \circ (y \cdot z) = (x \circ y) \cdot x^{- 1} \cdot (x \circ z)$ …

The multiple holomorph of split metacyclic $p$ -groups

Cindy Tsang

Given any group $G$ , the normalizer $Hol (G)$ of the subgroup of left translations in the group of all permutations on $G$ is called the holomorph, and the normalizer $\mat…

The multiple holomorph of a semidirect product of groups having coprime exponents

Cindy Tsang

Given any group $G$ , the multiple holomorph $NHol (G)$ is the normalizer of the holomorph $Hol (G) = ρ (G) ⋊ Aut (G)$ in the group of all permutations o…

Hopf-Galois structures on finite extensions with quasisimple Galois group

Cindy Tsang

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 pap…
