Mini-Workshop: Reflection Groups in Negative Curvature

Abstract

Discrete groups generated by reflections constitute an important source of examples of lattices in simple Lie groups of real rank $1$ (whose associated symmetric spaces are negatively curved). Yet a classification for them is far from being achieved, even in the case of hyperbolic geometry. The goal of this mini-workshop was to stimulate the research by bringing together specialists of different aspects of the theory.
