Matings, holomorphic correspondences, and a Bers slice

Mahan Mj, Sabyasachi Mukherjee

There are two frameworks for mating Kleinian groups with rational maps on the Riemann sphere: the algebraic correspondence framework due to Bullett-Penrose-Lomonaco \cite{BP94,BL20…

First Passage Percolation on Hyperbolic groups

Riddhipratim Basu, Mahan Mj

We study first passage percolation (FPP) on a Gromov-hyperbolic group $G$ with boundary $\partial G$ equipped with the Patterson-Sullivan measure $I^½$ . We associate an i.i.d.\ coll…

Cubulating Surface-by-free Groups

Jason F. Manning, Mahan Mj, Michah Sageev

Let $1 \to H \to G \to Q \to 1$ be an exact sequence where $H = I ¨ _{1} (S)$ is the fundamental group of a closed surface $S$ of genus greater than one, $G$ is hyperbolic and $Q$ is f…
