New Heegaard Floer slice genus and clasp number bounds
Year: 2026
Type: article
Abstract: We define several concordance invariants using knot Floer homology, which give improvements over known slice genus and clasp number bounds from Heegaard Floer homology. We also prove that the involutive correction terms of Hendricks and Manolescu give both a slice genus and a clasp number bound.
