Teichmüller theory and surfaces in 3-manifolds

course: Simplicial volume of compact manifolds with amenable boundary

speaker: Sungwoon Kim (Korea Institute for Advanced Study)

abstract: Let M be the interior of a connected, oriented, compact manifold V of dimension at least 2. If each path component of ∂V has amenable fundamental group, then we prove that the simplicial volume of M is equal to the relative simplicial volume of V and also to the Lipschitz simplicial volume of any Riemannian metric on M whenever the latter is finite. As an application we establish the proportionality principle for the simplicial volume of complete, pinched negatively curved manifolds of finite volume.
