Knot surgery and Heegaard Floer homology - Jennifer Hom
Members' Seminar Topic: Knot surgery and Heegaard Floer homology Speaker: Jennifer Hom Date: Monday, April 4 One way to construct new 3-manifolds is by surgery on a knot in the 3-sphere; that is, we remove a neighborhood of a knot, and reglue it in a different way. What 3-manifolds ca
