  The universal cover of certain negatively curved complex surfaces

Abstract: One dimensional complex manifolds are also known as Riemann surfaces. It is well known that the universal cover of a compact Riemann surface with a metric of negative curvature is biholomorphic to the unit disc in the complex plane. In higher dimensions, the situation is considerably more complicated, as was first illustrated by Mostow and Siu, who constructed negatively curved Kahler surfaces that are not diffeomorphic to any locally symmetric space. I will briefly present some of the issues involved in constructing such "exotic" surfaces, and describe some of their topological and complex analytic properties.
