Casson-Gordon and Reducing Heegaard Splittings

Student-Run Geometry/Topology Seminar

Speaker: George Mossessian, UC Davis
Location: 2112 MSB
Start time: Wed, Oct 10 2012, 4:10PM

I will introduce the notion of a Heegaard splitting for a compact 3-manifold with boundary, and following the result of Casson and Gordon, will explain their proof that a strongly irreducible Heegaard splitting for a 3-manifold M is either reducible or M is contains an incompressible surface of positive genus.
