DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CIRGET/95/">
 Almost L-space knots</a>\nby Fraser Binns (Boston College) as part of CRM 
 - Séminaire du CIRGET / Géométrie et Topologie\n\nLecture held in PK-51
 15.\n\nAbstract\nHeegaard Floer homology is a powerful package of invarian
 ts in low dimensional topology due originally to Ozsváth-Szabó. An L-spa
 ce knot is a knot admitting surgeries to a manifold with Heegaard Floer ho
 mology of minimal rank. Ozsváth-Szabó classified the knot Floer homology
  of L-space knots from which it follows that L-space knots satisfy various
  strong topological conditions. I will discuss a generalization of Ozsvát
 h-Szabó's result to "almost L-space knots"\; i.e. knots which admit surge
 ries to manifolds with Heegaard Floer homology of next to minimal rank.\n
