Syllabus:

The topic this semester will be Kleinian groups, discrete finitely generated subgroups of PSL_2(C).

Recently, the classification of these groups has been accomplished in terms of topological and conformal data.

Topics will include 3-manifold theory, the measurable Riemann mapping theorem,

currents and laminations on surfaces, pleated surfaces in hyperbolic 3-manifolds,

geometric tameness, the covering theorem, and the Ahlfors measure conjecture.

If there's time, we'll survey the curve complex and the ending lamination theorem,

and the orbifold and geometrization theorems.
