Abstract

If AA is an abelian quandle and QQ is a quandle, the hom set Hom(Q,A)\mathrm{Hom}(Q,A) of quandle homomorphisms from QQ to AA has a natural quandle structure. We exploit this fact to enhance the quandle counting invariant, providing an example of links with the same counting invariant values but distinguished by the hom quandle structure. We generalize the result to the case of biquandles, collect observations and results about abelian quandles and the hom quandle, and show that the category of abelian quandles is symmetric monoidal closed.
