|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.|
