| Feb 1, 2019 at 20:42 | comment | added | Deane Yang | I think the exponential dependence might be realized for hyperbolic manifolds. | |
| Feb 1, 2019 at 20:38 | comment | added | Piotr Hajlasz | @AndyMack I do not know examples showing sharpness of the inequality, but as far as I know this is the best inequality known. I would suggest to search who quoted the paper of Maheux and Saloff-Coste to see if there are better results. | |
| Feb 1, 2019 at 20:34 | comment | added | Andy Mack | Is this known to be tight? In particular, is it know the dependence on $\kappa$ and $D$ needs to be exponential? | |
