Title：Geometric decomposition and angle structure on general hyperbolic 3-manifolds
Language：Chinese
Abstract：Let M be a finite-volume non-compact complete hyperbolic n-manifold with totally geodesic boundary. We show that there exists a geometric decomposition of M such that each cell is either an ideal polyhedron or a partially truncated polyhedron with only one hyperideal vertex. We also show that M has an ideal triangulation which admits an angle structure under some topological conditions. This is joint work with Huabin Ge and Faze zhang.
