Đề tài " Laminations mesur´ees de plissage des vari´et´es hyperboliques de dimension 3 "
R´sum´ anglais e e For a hyperbolic metric on a 3-dimensional manifold, the boundary of its convex core is a surface which is almost everywhere totally geodesic, but which is bent along a family of disjoint geodesics. The locus and intensity of this bending is described by a measured geodesic lamination, which is a topological object. We consider two problems: the topological characterization of those measured geodesic laminations which can occur as bending measured laminations of hyperbolic metrics; and the uniqueness problem which asks whether a hyperbolic metric is uniquely determined by its bending measured lamination. ...
