Let $S$ be a closed surface of genus $g$. In this paper, we investigate the relationship between hyperbolic cone-structure on $S$ and representations of the fundamental group into $\text{PSL}_2\Bbb R$... We consider surfaces of genus greater than $g$ and we show that, under suitable conditions, every representation $\rho:\pi_1 S\longrightarrow \text{PSL}_2\Bbb R$ with Euler number $\mathcal{E}(\rho)=\pm\big(\chi(S)+1\big)$ arises as holonomy of a hyperbolic cone-structure $\sigma$ on $S$ with a single cone point of angle $4\pi$. From this result, we derive that for surfaces of genus $2$ every representation with $\mathcal{E}(\rho)=\pm1$ arises as the holonomy of some hyperbolic cone-structure. (read more)
