Greg McShane - Volumes of hyperbolics manifolds and translation distances
Description : Schlenker and Krasnov have established a remarkable Schlaffli-type formula for the (renormalized) volume of a quasi-Fuchsian manifold. Using this, some classical results in complex analysis and Gromov-Hausdorff  convergence for sequences of open 3-manifolds due to Brock-Bromberg one obtains explicit ...

Laurent Mazet - Some aspects of minimal surface theory (Part 2)
Description : In a Riemannian 3-manifold, minimal surfaces are critical points of the area functional and can be a useful tool to understand the geometry and the topology of the ambient manifold. The aim of these lectures is to give some basic definitions about minimal surface theory and present some results ...

Robert Young - Quantitative geometry and filling problems (Part 1)
Description : Plateau's problem asks whether there exists a minimal surface with a given boundary in Euclidean space. In this course, we will study related problems in broader classes of spaces and ask what the asymptotics of filling problems tell us about the geometry of surfaces in groups and spaces. What do ...
