Homology operations on homology of quandles. (English) Zbl 1219.55003

A notion of partial differential operators on rack homology is introduced and used to construct pre-homological and homological operations on rack and quandle homology. Previous results on dihedral quandles, Alexander quandles and Burnside kei are extended, and results on Fibonacci quandles and quasigroup quandles are obtained. Several interesting new conjectures are introduced, with direct verification in small-cardinality cases.
