Student Algebraic Geometry Seminar: The topology of normal surface singularities
Seminar | March 20 | 4-5 p.m. | 891 Evans Hall
Daniel Lowengrub, UC Berkeley
In the paper "The topology of normal singularities of an algebraic surface and a criteria for simplicity" Mumford shows how it is possible to check if a point on a normal surface is singular based on purely topological properties of a neighborhood of the point. We will present a precise formulation of this idea and discuss the ingredients that go into the proof.
