Rack shadows and their invariants

Geometric Topology 2010-07-14 v2 Quantum Algebra

Abstract

A rack shadow is a set X with a rack action by a rack R, analogous to a vector space over a field. We use shadow colorings of classical link diagrams to define enhanced rack counting invariants and show that the enhanced invariants are stronger than unenhanced counting invariants.
