Spectrum of SL(2,R)-characters: the once-punctured torus case

Selim Ghazouani, Florestan Martin-Baillon

Consider a topological surface $I^£$ . We introduce the spectrum of a representation from the fundamental group of $I^£$ to SL(2,R), which is a subset of projective measured laminatio…

Rigidity of the dynamics of $Aut (F_{n})$ on representations into a compact group

Serge Cantat, Christophe Dupont, Florestan Martin-Baillon

Let $G$ be a compact Lie group. Let $F_{n}$ be the free group of rank $n$ . We describe the orbits of $Aut (F_{n})$ on $Hom (F_{n}; G)$ whe…

Bridging Arbitrary and Tree Metrics via Differentiable Gromov Hyperbolicity

Pierre Houedry, Nicolas Courty, Florestan Martin-Baillon +2

Trees and the associated shortest-path tree metrics provide a powerful framework for representing hierarchical and combinatorial structures in data. Given an arbitrary metric space…
