Title:Bilipschitz classification of complex surface singularities
Seminar:Center for Dynamics and Geometry Seminars
Speaker:Walter Neumann, Columbia University
Joint work with Lev Birbrair and Anne Pichon. It is only relatively recently that it has become clear how much information is encoded in the local geometry of a complex surface. I will describe how the bilipschitz geometry in a neighborhood of a point determines and is determined by a refined JSJ decomposition of the 3-manifold link of the point together with discrete data associated with pieces of this decomposition. This classification has application to equisingularity questions, L^p cohomology, and elsewhere.
