A note on complete hyperbolic structures on ideal triangulated 3-manifolds
arXiv:1010.3591
Abstract
It is a theorem of Casson and Rivin that the complete hyperbolic metric on a cusp end ideal triangulated 3-manifold maximizes volume in the space of all positive angle structures. We show that the conclusion still holds if some of the tetrahedra in the complete metric are flat.
