Some Applications of Hyperbolic Geometry to Superstring Perturbation Theory

The amplitudes in superstring perturbation theory are defined by the integration of proper objects over the space of surfaces. Since the spaces of surfaces have delicate structures, there are thus two immediate questions that need to be answered: how to parametrize the space of surfaces and how to perform the integration? In this talk, I will argue that the recent developments in studying the space of surfaces using hyperbolic geometry provide the required tools to compute the superstring amplitudes.
