Equivariant annular Khovanov homology

Abstract

We construct an equivariant version of annular Khovanov homology via the Frobenius algebra associated with $U(1)\times U(1)$-equivariant cohomology of ${\mathbb{CP}}^1$. Motivated by the relationship between the Temperley-Lieb algebra and annular Khovanov homology, we also introduce an equivariant analogue of the Temperley-Lieb algebra.
