Abstract/Media

The moduli space of n points on a sphere carries many natural complex hyperbolic metrics, whose completions are sometimes orbifolds and always cone manifolds (Picard, Deligne—Mostow, Thurston). We will discuss a generalization of the Gauss-Bonnet formula to this setting, use it to calculate the volumes, and relate the results to non-arithmetic lattices in SU(1,n).
