Abelian fixed point free endomorphisms and the Yang-Baxter equation
Alan Koch, Laura Stordy, Paul J. Truman
We obtain a simple family of solutions to the set-theoretic Yang-Baxter equation, one which depends only on considering special endomorphisms of a finite group. We show how such an…
Opposite skew left braces and applications
Alan Koch, Paul J. Truman
Given a skew left brace , we introduce the notion of an "opposite" skew left brace , which is closely related to the concept of the opposite of a group…
Isomorphism problems for Hopf-Galois structures on separable field extensions
Alan Koch, Timothy Kohl, Paul J. Truman +1
Let be a finite separable extension of fields whose Galois closure has group . Greither and Pareigis have used Galois descent to show that a Hopf algebra givin…
Normality and Short Exact Sequences of Hopf-Galois Structures
Alan Koch, Timothy Kohl, Paul J. Truman +1
Every Hopf-Galois structure on a finite Galois extension where corresponds uniquely to a regular subgroup , normalized by $λ(G)\l…
