SUMMARY:John Baldwin: \"Capping off open books and the Ozsvath-Szabo con
 tact invariant\"
DESCRIPTION:Abstract: If (S\,h) is an open book with disconnected bindin
 g then we can form a new open book (S'\,h') by capping off one of the bo
 undary components of S with a disk. I'll describe a U-equivariant map on
  Heegaard Floer homology which sends c^+(S'\,h') to c^+(S\,h)\, and I'll
  discuss various applications.
