Infinitesimal sl(2)-symmetries on the equivariant skein lasagna module

You Qi, Louis-Hadrien Robert, Joshua Sussan +2

We construct an sl(2)-action on the equivariant skein lasagna module.

Invariants of surfaces in smooth 4-manifolds from link homology

Kim Morrison, Kevin Walker, Paul Wedrich

We construct analogs of Khovanov-Jacobsson classes and the Rasmussen invariant for links in the boundary of any smooth oriented 4-manifold. The main tools are skein lasagna modules…

Monoidal 2-categories from foam evaluation

Leon J. Goertz, Laura Marino, Paul Wedrich

In this paper we describe a general framework for constructing examples of locally linear semistrict monoidal 2-categories covering many examples appearing in link homology theory.…

A note on TQFTs for orientable 2-dimensional cobordisms

Leon J. Goertz, Paul Wedrich

Topological quantum field theories (TQFTs) are symmetric monoidal functors out of cobordism categories. In dimension two, oriented TQFTs are famously classified by commutative Frob…

Khovanov skein lasagna modules with -dimensional inputs

Qiuyu Ren, Ian Sullivan, Paul Wedrich +2

We construct a variant of Khovanov skein lasagna modules, which takes the Khovanov homology in connected sums of defined by Rozansky and Willis as the input link ho…

From Link Homology to Topological Quantum Field Theories

Paul Wedrich

This survey reviews recent advances connecting link homology theories to invariants of smooth 4-manifolds and extended topological quantum field theories. Starting from joint work…
