Modules over semisymmetric quasigroups

Rings and Algebras 2019-08-20 v1

Abstract

The class of semisymmetric quasigroups is determined by the identity (yx)y=x.(yx)y=x. We prove that the universal multiplication group of a semisymmetric quasigroup QQ is free over its underlying set and then specify the point-stabilizers of an action of this free group on QQ. A theorem of Smith indicates that Beck modules over semisymmetric quasigroups are equivalent to modules over a quotient of the integral group algebra of this stabilizer. Implementing our description of the quotient ring, we provide some examples of semisymmetric quasigroup extensions. Along the way, we provide an exposition of the quasigroup module theory in more general settings.
