| Dec 1, 2013 at 14:16 | comment | added | Joseph O'Rourke | This may not be what @RyanBudney had in mind, but: Robin Forman defines a notion of combinatorial curvature in his D&CG paper, "Bochner's Method for Cell Complexes and Combinatorial Ricci Curvature" (Springer link). | |
| Dec 1, 2013 at 13:34 | comment | added | Ryan Budney | In the direction of Joseph's answer I believe there are a variety of notions of combinatorial curvature, where one is talking about triangulated manifolds, perhaps with some combinatorial analogue of a metric. It would be nice to have a few concrete examples of these. I don't know the literature well-enough myself to give anywhere near a complete answer to that. | |
| Dec 1, 2013 at 13:19 | comment | added | Benoît Kloeckner | As I voted to close, I should probably explain more why. I think there may be a good question here (actually, two), but it seems like the OP has not done a thorough bibliographic search first. Also, more motivation would be welcome. That said, my vote is borderline and I don't see much harm if the question stays open. | |
| Dec 1, 2013 at 13:15 | comment | added | Ryan Budney | I think this is a good basic question. There are a couple votes to close but I'd like to suggest we leave this open. I think there are a few good answers already, and likely there will be more. | |

removed inapplicable tag 'at.algebraic-topology' (I also don't think 'gt.geometric-topology' is appropriate, but...); added 'riemannian-geometry'

| Nov 29, 2013 at 17:25 | comment | added | Benoît Kloeckner | Question 1. Is clearly out of scope, except maybe if you consider Scalar and Ricci curvature to be part of Riemann curvature (which is more a tensor that leads to curvatures than a curvature by itslef). Even so, it needs little work to find generalizations of these (to graphs, metric spaces, measure-metric spaces, Markov chains) For Question 2 I guess the answer is Ehresman, but that needs checking. | |
