| Feb 22, 2017 at 15:38 | comment | added | Dirk | You're welcome. The answer to your question is no, since affine functions are also in $\Gamma_0(H)$. I don't think that you get a more handy description as "convex, proper and lsc" or "suprema of affine function, but not constant $\pm\infty$. | |
| Feb 22, 2017 at 15:31 | comment | added | MMFF | Thank you for your detailed answer. Could we therefore say that $\Gamma_0(H)$ is the set of the functions belonging to $\Gamma(H)$ that admit the horizontal (zero) hyperplane as supporting hyperplane? | |
