Abstract
What do annular Khovanov homology, Ozsvath-Szabo's "correction terms", Kapustin-Witten equations, and enumerative BPS invariants have in common The goal of the talk will be to explain, from multiple perspectives, how this structure makes a somewhat surprising appearance in a problem of generalizing Khovanov homology to homology of knots in arbitrary 3-manifolds.
