Title:K(pi,1) property of complements to curve arrangements on surfaces.
Seminar:Center for Dynamics and Geometry Seminars
Speaker:Dmitri Panov, King's College
Abstract:
It is a non-trivial question to understand when a complement to a collection of curves on a complex surface is of type K(pi,1). We will explain that such a property (which is rather rare by itself) holds in cases when one can construct on the surface a non-positively curved Kaehler metric with conical singularities of angles less than 2pi along the collection of curves that intersect pairwise transversally. The talk is based on a joint work with Anton Petrunin.
