Quandle Identities and Homology

Geometric Topology 2016-03-01 v1

Abstract

Quandle homology was defined from rack homology as the quotient by a subcomplex corresponding to the idempotency, for invariance under the type I Reidemeister move. Similar subcomplexes have been considered for various identities of racks and moves on diagrams. We observe common aspects of these identities and subcomplexes; a quandle identity gives rise to a 22-cycle, the abelian extension with a 22-cocycle that vanishes on the 22-cycle inherits the identity, and a subcomplex is constructed from the identity. Specific identities are examined among small connected quandles.
