SUMMARY:Yanki Lekili: \"Heegaard Floer homology of broken fibrations\"
DESCRIPTION:Abstract: We will outline a programme for identifying Perutz
 's Lagrangian matching invariants and Ozsvath-Szabo's Heegaard Floer inv
 ariants of three and four manifolds. In this talk\, we will deal with pu
 rely Heegaard Floer theoretical side of this programme and describe the 
 isomorphism of 3--manifold invariants for certain Spin^c structures wher
 e the groups involved can be formulated in the language of Heegaard Floe
 r theory. As applications\, we give new calculations of Heegaard Floer h
 omology of certain classes of 3--manifolds and an outline of a proof of 
 Floer's excision theorem in the context of Heegaard Floer homology.
