Bikei Homology

Geometric Topology 2016-05-17 v2 Quantum Algebra

Abstract

We introduce a modified homology and cohomology theory for involutory biquandles (also known as \textit{bikei}). We use bikei 2-cocycles to enhance the bikei counting invariant for unoriented knots and links as well as unoriented and non-orientable knotted surfaces in R4\mathbb{R}^4.
