$f$-Racks, $f$-Quandles, their Extensions and Cohomology

Abstract

The purpose of this paper is to introduce and study the notions of $f$-rack and $f$-quandle which are obtained by twisting the usual equational identities by a map. We provide some key constructions, examples and classification of low order $f$-quandles. Moreover, we define modules over $f$-racks, discuss extensions and define a cohomology complex for $f$-quandles.

We have changed the title, added couple of examples and corrected some typos. To be appeared in Journal of Algebra and its Applications
