DESCRIPTION:Heegaard Floer homology and graph manifolds.\n\nBetween you and
  me\, I always wanted to be a geometric group theorist. On that note\, the
 re is a conjectural relationship between Heegaard Floer homology and left-
 orderable three-manifold groups\, which is now known to hold for all graph
  manifolds. That is\, a closed orientable graph manifold Y is an L-space i
 f and only if the fundamental group of Y is not-left-orderable. The latter
  condition can be hard to check in general\, but in this setting the inequ
 ality dimHF(Y)>|H_1(Y)| provides a certificate that the group pi_1(Y) is l
 eft-orderable. I'll explain what these symbols mean in an attempt to sell 
 the machinery to geometric group theorists.\n
