Geometry and Topology Seminar

In this joint work with Feng Luo, we prove that a hyperbolic cone metric on an ideally triangulated compact 3-manifold with boundary consisting of surfaces of negative Euler characteristic is determined by its combinatorial curvature. The proof uses a convex extension of the Legendre transformation of the volume function. Depending on the time, several related results on maximum volumed semi-angle structures will also be mentioned.
