Abstract
The importance of manifolds with constant sectional curvatures equal to -1 can hardly be overstated. Some of the milestones in modern Mathematics, such as Riemann's Uniformisation Theorem and Thurston's Hyperbolisation Theorem, revolve around hyperbolic 2- and 3-manifolds. These objects, in turn, are inexorably linked to the understanding of Fuchsian and Kleinian groups.The arithmetic pro…
