Density of almost squares of horospherical orbits in non-uniform quotients of ${\mathrm{SL}}_2(\mathbb{R})\times {\mathrm{SL}}_2(\mathbb{R})$

Konstantin Andritsch

Let $\Gamma \subset {\mathrm{SL}}_2(\mathbb{R})\times {\mathrm{SL}}_2(\mathbb{R})$ be an irreducible, non-uniform lattice and define the space $X = \operatorname{SL}_2(\mathbb{R})\…
