Limit cones of multi-Fuchsian representations
Jeffrey Danciger, François Guéritaud, Fanny Kassel
We study the set of normalized multi-lengths for representations of closed surface groups and free groups into whose projections to $\mathrm{PSL}_2\m…

Convex cocompactness for Coxeter groups
Jeffrey Danciger, François Guéritaud, Fanny Kassel +2
We investigate representations of Coxeter groups into as geometric reflection groups which are convex cocompact in the projective space $\mathbb{P}(\mat…
