内容摘要：The moduli space of a surface is the space of all different complex structures on the surface. The moduli space of a hyperbolic surface is a complex manifold equipped with a Kahler metric – the Weil-Petersson metric, which is induced by the natural inner product of quadratic differentials. In this talk, we discuss the Weil-Petersson geometry of the moduli spaces of hyperbolic surfaces with finite area, as well as the universal Teichmüller space (the universal moduli space). In particular, we discuss the construction of the potential of the Weil-Petersson metric– the classical Liouville action which was motivated by string theory. We demonstrate the relation between the Liouville action and the renormalized volume of a corresponding hyperbolic three manifold. We also discuss the local index theorem on the moduli spaces.
