Title: Compact forms of spaces of constant negative (sectional) curvature.
Abstract: One knows that any compact riemann surface of genus > 2 carries
a riemanniann metric of constant curvature. In higher dimension even the
existence of compact manifolds of constant negative curvature is by no
means that abundant. In this lecture we will show how arithmetic enables us
to construct such manifolds in every dimension greater than equal to 2.
