Such a function (convex decreasing and defined on $\mathbb{R}$) seems to be zero. The limit should be taken for $ \lim_{x \to +\infty}f(x)=0.$

| Feb 23, 2015 at 9:28 | comment | added | Denis Serre | Although I liked Bob's answer (and voted it), I doubt that it solves completely the question, because it deals with only one light ray. It proves that every light ray $R$ must bounce back at some abcissa $X(R)$. But it does not prove that $XR)$ is bounded independently on the initial direction of the ray. | |
| Feb 23, 2015 at 6:30 | comment | added | Gerry Myerson | I believe that's the definition of crossposting. "Migrated" is a technical term in the stackexchange network, and is something that can only be done by moderators, and, when it is done, the question no longer appears at the original site. So, whatever you did, it's not migration. | |

| Feb 22, 2015 at 22:30 | comment | added | Gerry Myerson | By "migrated", you mean "crossposted". The problem is still there on m.se. | |
