Type: article
Abstract: We describe a formula for the H 1 -action on the knot Floer homology of knotifications of links in S 3 .Using our results about knotifications, we are able to study complex curves with noncuspidal singularities, which were inaccessible using previous Heegaard Floer techniques.We focus on the case of a transverse double point, and give examples of complex curves of genus g which cannot be topologically deformed into a genus g 1 surface with a single double point.14H50; 14B05, 57K18, 57R58 1.
