| Sep 10 at 15:17 | comment | added | Antonius | Sorry, what I meant was the hyperbolic 2 space. But 3 dimensional space doesn't sound like surface to me. But indeed, where do I find this result? | |
| Sep 10 at 14:32 | comment | added | Moishe Kohan | I do not think you understand the surface case. Have you read about convex hulls of limit sets of finitely generated discrete groups in hyperbolic 3-space? They are never smooth unless the subgroup is not Zariski dense. What sources did you consult? | |
| Sep 10 at 13:05 | comment | added | Antonius | The surface case is clear to me. My question refers to higher dimensions. I also think the question is not si much about convex geometry, as for the answers the shape of the limit set is decisive, which in the surface case can be quite nasty. | |
| Sep 10 at 13:03 | comment | added | Antonius | Sorry, I meant as smooth Riemann manifolds, or at least as smooth manifolds. | |

| Sep 10 at 10:58 | comment | added | Moishe Kohan | In what category do you consider manifolds with boundary/corners? If purely topological then you should clarify what you mean by a manifold with corners (since in TOP, this is just an extra structure one can impose on manifolds with boundary). If smooth, did you think of any examples, e.g. the case $G=SL(2,C)$? D you know about pleated surfaces? All in all, apart from lack of clarity, this is a nice convex geometry exercise. | |
