SUMMARY:Lefschetz fibrations and Stein surfaces
DESCRIPTION:Speaker: Selman Akbulut\, Michigan State\n\nWe will discuss some geometric structures on smooth 4-manifolds as a tool to understand their topology. For example, every closed smooth 4-manifold can be decomposed as a union of two Stein surfaces, and a Stein surface is nothing more than a Lefschetz fibration on a 2-disk.
