Title: Foliations, topology and geometry of 3-manifolds: $R$-covered foliations and transverse pseudo-Anosov flows
Abstract: We analyse the topological and geometrical behavior of foliations in 3-manifolds. We consider the transverse structure of an R-covered foliation in a 3-manifold, where R-covered means that in the universal cover the leaf space of the foliation is Hausdorff and hence homeomorphic to the real numbers. If the manifold is aspherical we prove that either there is an incompressible torus in the manifold; or there is a transverse pseudo-Anosov flow which captures the directions of maximal stretch/contraction transverse to the foliation. A consequence is that 3-manifolds with R-covered foliations satisfy the weak hyperbolization conjecture.

Abstract: We will discuss conformal deformations of finite volume hyperbolic n-manifolds, especially for n=3. We start with a survey of many ways to construct such deformations, starting with well known bendings along totally geodesic submanifolds, as well as possible components of Teichmuller space. Such deformations give rise canonical hyperbolic stratifications of initial hyperbolic manifold and its geodesic laminations. These laminations may have (geodesic) singularities. Understanding of such laminations and their properties is crucial for Teichmuller theory.(彯偙偺島墘偼
