SUMMARY:Branched cyclic covers and L-spaces
LOCATION:zoom link:  https://rutgers.zoom.us/j/96007672653?pwd=UkhZV0l0WWNVenFqY1FYd

DESCRIPTION:A 3-manifold is called an L-space if its Heegaard Floer homology is "simple
 ." No characterization of all such "simple" 3-manifolds is known. Manifolds
  obtained as the double-branched cyclic cover of a knot in the 3-sphere giv
 e many examples of L-spaces. In this talk, I'll discuss the search for L-sp
 aces among higher index branched cyclic covers of knots. In particular, I'l
 l give new examples of knots whose branched cyclic covers are L-spaces for 
 every index n. This is joint work with Ahmad Issa.\n
