摘要
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 theory for f-quandles and give examples.
