<p>Theorem 2.9. (Rudolph [Rud89]) Suppose $X_{T}$ is a finite local complexity (FLC) tiling space. Then $X_{T}$ is compact in the tiling metric d. Moreover, the action $T$ of $R^{d}$ by translation is on $X_{T}$ is continuous. -Probleme : We substitute $R^{d}$ par hyperbolic space $H^{d}$ ?? we can an answer positive?, in particular d=2,</p> <p>-Can you help me link to the proof of this theorem or the document: ++Daniel J.
