The 3-cocycles of the Alexander quandles F_q[T]/(T-omega)

Takuro Mochizuki

Abstract. We determine the third cohomology of Alexander quandles of the form F_q[T]/(T-omega), where F_q denotes the finite field of order q and omega is an element of F-q which is neither 0 nor 1. As a result, we obtain many concrete examples of non-trivial 3-cocycles.

Keywords. Quandle, cohomology, knot
