A Gravitational Effective Action on a Finite Triangulation as a Discrete Model of Continuous Concepts

Albert Ko, Martin Rocek

We recall how the Gauss-Bonnet theorem can be interpreted as a finite dimen- sional index theorem. We describe the construction given in hep-th/0512293 of a function that can be in…

A Gravitational Effective Action on a Finite Triangulation

Albert Ko, Martin Rocek

We construct a function of the edge-lengths of a triangulated surface whose variation under a rescaling of all the edges that meet at a vertex is the defect angle at that vertex. W…
