On totally hyperbolic non-Fuchsian type-preserving representations

Abstract

We identify type-preserving representations $\varphi :{\pi }_1(\Sigma )\to \mathrm{PSL}(2,\mathbb{R})$ of the fundamental group of every punctured surface $\Sigma ={\Sigma }_{g,p}$ that are not Fuchsian yet send all non-peripheral simple closed curves to hyperbolic elements, which give a negative answer to a question of Bowditch. These representations have relative Euler class $e(\varphi )=\pm (\chi (\Sigma )+1)$, and their $\mathrm{PSL}(2,\mathbb{R})$-conjugacy classes form a full-measure subset of $2p$ connected components of the relative character variety. We further show that, while these representations are not Fuchsian, their restrictions to certain subsurfaces of $\Sigma$ are Fuchsian.
