On the Khovanov homology of 3-braids
Dirk Schuetz
We prove the conjecture of Przytycki and Sazdanovic that the Khovanov homology of the closure of a 3-stranded braid only contains torsion of order 2. This conjecture has been known…

Efficient calculations of -invariants for links
Dirk Schuetz
We describe an algorithm that can effectively calculate the -invariant of a link as defined by Beliakova and Wehrli. Our computations show that this cannot be done by merely cal…

On Variations of s-invariants from sl(3)-link homology
Dirk Schuetz
We use the Mackaay-Vaz universal -link homology to deepen the study of -invariants on Khovanov's link homology associated to . Such -invariants have already bee…
