Cocycle invariants for links in the projective space

D. V. Gorkovets

Chelyabinsk State University

Abstract: We introduce a definition of proper colorings of the diagram by the elements of the finite groupoid. We introduce an invariant for links in the projective space, based on the cocycle homology theory.

Keywords: link, projective space, groupoid, quandle, cocycle invariant.
