Student Dyn/Geo/Top: Heegaard Floer Homology and Unknotting Number
Nathan Li
Heegaard Floer homology is a powerful topological invariant of
3-manifolds and knots. The unknotting number is an invariant of knots
that is easy to define but can be difficult to compute. In this talk,
I will review some results that show how Heegaard Floer homology has
been used to determine unknotting numbers of certain knots.
