Efficient calculations of S-invariants for links
Abstract
We describe an algorithm that can effectively calculate the s-invariant of a link as defined by Beliakova and Wehrli. Our computations show that this cannot be done by merely calculating the E∞-page of the Bar-Natan--Lee--Turner spectral sequence. Our methods also work for s-invariants coming from sl(3)-link homology.
