Abstract:
Heegaard Floer homology is a homological invariant of 3-manifolds and knots whose Euler characteristic is the Alexander polynomial. It detects knot genus (or more generally the Thurston norm) and fibration, and has many other uses. It is conjecturally isomorphic to Seiberg-Witten Floer homology, and as such is essentially a 4-dimensional theory. In this series we will extend Heegaard-Floer homology to bordered 3-manifolds, i.e., 3-manifolds with parametrized boundary: To a connected, parametrized surface we associate a differential graded algebra, and to a 3-manifold with boundary we associate a differential module over that algebra, well-defined up to quasi-isomorphism. We will recall the construction of Heegaard Floer homology as we go along.
This is joint work with Robert Lipshitz and Peter Ozsváth.
