Comprehensive introduction to the geometric and topological structure of Kleinian groups. Starts with Möbius transformations acting on the (extended) complex plane. The next chapter concerns discrete groups of hyperbolic isometries in nspace. This part ends with a discussion of elementary Kleinian groups, and the Fuchsian groups. The second part of the book treats more advanced topics such as geometrically finite groups.
