On an integral version of the Rasmussen invariant

Dirk Schuetz

We define a Rasmussen -invariant over the coefficient ring of the integers, and show how it is related to the -invariants defined over a field. A lower bound for the slice ge…

Arbitrarily large torsion in Khovanov cohomology

Sujoy Mukherjee, Dirk Schuetz

For any positive integer and we construct a link which has a direct summand in its Khovanov cohomology.

Khovanov homotopy calculations using flow category calculus

Andrew Lobb, Patrick Orson, Dirk Schuetz

The Lipshitz-Sarkar stable homotopy link invariant defines Steenrod squares on the Khovanov cohomology of a link. Lipshitz-Sarkar constructed an algorithm for computing the first t…

A Khovanov stable homotopy type for colored links

Andrew Lobb, Patrick Orson, Dirk Schuetz

We extend Lipshitz-Sarkar's definition of a stable homotopy type associated to a link L whose cohomology recovers the Khovanov cohomology of L. Given an assignment c (called a colo…

Morse moves in flow categories

Dan Jones, Andrew Lobb, Dirk Schuetz

We pursue the analogy of a framed flow category with the flow data of a Morse function. In classical Morse theory, Morse functions can sometimes be locally altered and simplified b…

An sl_n stable homotopy type for matched diagrams

Dan Jones, Andrew Lobb, Dirk Schuetz

There exists a simplified Bar-Natan Khovanov complex for open 2-braids. The Khovanov cohomology of a knot diagram made by gluing tangles of this type is therefore often amenable to…
