Title: A few refinements of Heegaard Floer genus and clasp number bounds

Abstract
In this talk, we will describe several new knot Floer concordance invariants which give improvements over the known Heegaard Floer 4-ball genus and clasp number bounds, and also describe how to obtain new bounds from familiar concordance invariants. This is joint work with Andras Juhasz.
