Knot invariants arising from homological operations on Khovanov homology

KK Putyra, AN Shumakovitch - Journal of Knot Theory and Its …, 2016 - World Scientific
We construct an algebra of nontrivial homological operations on Khovanov homology with
coefficients in ℤ 2 generated by two Bockstein operations. We use the unified Khovanov …

Torsion in Khovanov homology of homologically thin knots

AN Shumakovitch - Journal of Knot Theory and Its Ramifications, 2021 - World Scientific
We prove that every ℤ 2 H-thin link has no 2 k-torsion for k> 1 in its Khovanov homology.
Together with previous results by Lee [The support of the Khovanov's invariants for …

Fixing the functoriality of Khovanov homology: a simple approach

T Sano - Journal of Knot Theory and Its Ramifications, 2021 - World Scientific
Khovanov homology is functorial up to sign with respect to link cobordisms. The sign
indeterminacy has been fixed by several authors, by extending the original theory both …

A spanning tree model for Khovanov homology

S Wehrli - Journal of Knot Theory and Its Ramifications, 2008 - World Scientific
We show that the Khovanov complex of a connected link diagram D retracts to a subcomplex
whose generators are in 2: 1 correspondence with the spanning trees of the" black graph" of …

Doubled Khovanov Homology

W Rushworth - Canadian Journal of Mathematics, 2018 - cambridge.org
We define a homology theory of virtual links built out of the direct sum of the standard
Khovanov complex with itself, motivating the name doubled Khovanov homology. We …

Equivariant annular Khovanov homology

R Akhmechet - Journal of Knot Theory and Its Ramifications, 2023 - World Scientific
We construct an equivariant version of annular Khovanov homology via the Frobenius
algebra associated with U (1)× U (1)-equivariant cohomology of ℂ ℙ 1. Motivated by the …
