Abstract

In this article, we prove several results about the extension to the boundary of conformal immersions from an open subset Ω\Omega of a Riemannian manifold LL into another Riemannian manifold NN of the same dimension. In dimension n3n \geq 3, and when the (n1)(n-1)-dimensional Hausdorff measure of Ω\partial \Omega is zero, we completely classify the cases when Ω\partial \Omega contains essential singular points, showing that LL and NN are conformally flat and making the link with the theory of Kleinian groups.
