Discreteness Of Hyperbolic Isometries by Test Maps

Krishnendu Gongopadhyay, Abhishek Mukherjee, Devendra Tiwari

Let $F = R$ , $C$ or $H$ . Let $H_{F}^{n}$ denote the $n$ -dimensional $F$ -hyperbolic space. Let $U (n, 1; F)$ be the lin…

On discreteness of subgroups of quaternionic hyperbolic isometries

Krishnendu Gongopadhyay, Mukund Madhav Mishra, Devendra Tiwari

Let $H_{H}^{n}$ denote the $n$ -dimensional quaternionic hyperbolic space. The linear group $Sp (n, 1)$ acts by the isometries of $H_{H}^{n}$ . A sub…
