Annular Khovanov homology and meridional disks

Abstract

We exhibit infinite families of annular links for which the maximum nonzero annular Khovanov grading grows infinitely large but the maximum nonzero annular Floer-theoretic gradings are bounded. We also show this phenomenon exists at the decategorified level for some of the infinite families. Our computations provide further evidence for the wrapping conjecture of Hoste–Przytycki and its categorified analogue. Additionally, we show that certain satellite operations be used to construct counterexamples to the categorified wrapping conjecture. We also extend the Batson–Seed link splitting spectral sequence to the setting of annular Khovanov homology.
