| May 8, 2012 at 20:12 | comment | added | Autumn Kent | Leininger has pointed out to me that the set of arcs does not depend on $\Gamma$, since they are determined by topological data (the lifts of simple curves on $S$ to $\mathbb{H}^2$ ``link" the limit set, and this linking data, which is really topological, determines the arcs you get). So the map $T(\Gamma) \to M(\Gamma_B)$ will be bounded for these filling groups $B$. | |
