Invariant measures for Deroin-Tholozan representations

Yohann Bouilly, Arnaud Maret

We classify mapping class group invariant probability measures on the character varieties of Deroin-Tholozan representations, namely the compact components of relative $\mathrm{PSL…

On the symplectic geometry of branched hyperbolic surfaces in genus two

Gianluca Faraco, Arnaud Maret

We construct analogues of Fenchel-Nielsen coordinates on an open and dense subset of the space of holonomies of branched hyperbolic structures on a closed genus-2 surface. We show…

Mapping class group orbit closures for Deroin-Tholozan representations

Yohann Bouilly, Gianluca Faraco, Arnaud Maret

We prove that infinite mapping class group orbits are dense in the character variety of Deroin-Tholozan representations. In other words, the action is minimal except for finite orb…

Tykhyy's Conjecture on finite mapping class group orbits

Samuel Bronstein, Arnaud Maret

We classify the finite orbits of the mapping class group action on the character variety of Deroin--Tholozan representations of punctured spheres. In particular, we prove that the…

The geometry of Deroin-Tholozan representations

Aaron Fenyes, Arnaud Maret

We present a way to build hyperbolic spheres with conical singularities by gluing together simple building blocks. Our construction provides good control over the holonomy of the r…

Totally elliptic surface group representations

Arnaud Maret

A surface group representation into a Lie group is called totally elliptic if every simple closed curve on the surface is mapped to an elliptic element of the target group. In this…
