A note on thickness of knots
Andras I. Stipsicz, Zoltan Szabo
We introduce a numerical invariant β(K) of a knot K which measures how non-alternating K is. We prove an inequality between β(K) and the (knot Floer) thickness of K. As an applicat…

Algebras with matchings and link Floer homology
Peter Ozsvath, Zoltan Szabo
We explain how to use bordered algebras to compute a version of link Floer homology. As a corollary, we also give a fast computation of the Thuston polytope for links in the three-…
