Applications of Heegaard Floer Homology
Heegaard Floer theory was introduced in 2001 by Ozsvath and Szabo. The theory provides a package of invariants for 3-manifolds, smooth 4-manifolds and knots. It has proved to be a powerful tool, leading to many important advances in low-dimensional topology and solutions to long-standing problems that resisted previously known methods. Glorious as it sounds, it comes with a price; it is difficult and technical. Hence, this seminar aims to study some of its applications in order to understand it a little better. Our focus is on questions about knots and surgeries.
