3-Dimensional Discrete curvature flows and discrete Einstein metric

Published 3 Dec 2013 in math.DG and math.GT | (1312.0730v1)

Abstract: We introduce the discrete Einstein metrics as critical points of discrete energy on triangulated 3-manifolds, and study them by discrete curvature flow of second (fourth) order. We also study the convergence of the discrete curvature flow. Discrete curvature flow of second order is an analogue of smooth Ricci flow.
