| 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. |
