Title:Introduction to Heegaard Floer homology, part III

Abstract: Heegaard Floer (HF) homology is a theory introduced by
Ozsvath and Szabo. Using ideas and techniques from symplectic
geometry, they associate a package of invariants to low dimensional
objects, like 3-manifolds, 4-manifolds, knots and links. This series
of talks aims to give a very brief introduction to Heegaard Floer
homology. After an overview of the theory, we will cover the
following topics: Morse homology, symplectic geometry and the
definition of Heegaard Floer homology, holomorphic disks,
combinatorial approaches to HF.
