An Extension of Khovanov Homology to Immersed Surface Cobordisms

Scott Carter, Benjamin Cooper, Mikhail Khovanov +1

We show that an oriented surface in containing double point singularities induces a map between the Khovanov homology groups of its boundary links in a functorial wa…

A new approach to (3+1)-dimensional TQFTs via topological modular forms

Sergei Gukov, Vyacheslav Krushkal, Lennart Meier +1

In this paper, we present a construction toward a new type of TQFTs at the crossroads of low-dimensional topology, algebraic geometry, physics, and homotopy theory. It assigns TMF-…

A triple torsion linking form and 3-manifolds in

Michael Freedman, Vyacheslav Krushkal

Given a rational homology 3-sphere , we introduce a triple linking form on , defined when the classical torsion linking pairing of three homology classes van…

Spineless 5-manifolds and the deformation conjecture

Michael Freedman, Vyacheslav Krushkal, Tye Lidman

We construct a compact PL 5-manifold (with boundary) which is homotopy equivalent to the wedge of eleven 2-spheres, , which is "spineless", meaning is not…

On the universal pairing for 2-complexes

Mikhail Khovanov, Vyacheslav Krushkal, John Nicholson

The universal pairing for manifolds was defined and shown to lack positivity in dimension 4 by Freedman et al. We prove an analogous result for 2-complexes, and also show that the…

Pseudo-isotopies of simply connected 4-manifolds

David Gabai, David T. Gay, Daniel Hartman +2

Perron and Quinn gave independent proofs in 1986 that every topological pseudo-isotopy of a simply-connected, compact topological 4-manifold is isotopic to the identity. Another re…
