Combinatorial Ricci flow on compact 3-manifolds with boundary

摘要

Combinatorial Ricci flow on an ideally triangulated compact 3-manifold with boundary was introduced by Luo as a 3 dimensional analogue of Chow-Luo's combinatorial Ricci flow on a triangulated surface and conjectured to find algorithmically the hyperbolic metric on the compact 3 manifold with totally geodesic boundary. In this paper, we prove Luo's conjecture affirmatively by extending the combinatorial Ricci flow through the singularities of the flow if the ideally triangulated compact 3-manifold with boundary admits such a metric.(c) 2022 Elsevier Inc.
