  1. Geometry: Maximally symmetric Riemannian metrics and Einstein metrics on Lie groups

    Location: MSRI: Simons Auditorium
    Speakers: Carolyn Gordon (Dartmouth College)
    All known examples of homogeneous Einstein metrics of negative Ricci curvature can be realized as left-invariant Riemannian metrics on solvable Lie groups.   After defining a notion of maximal symmetry among left-invariant Riemannian metrics on a Lie group, we show that any left-invariant Einstein metric of negative Ricci curvature on a solvable Lie group is maximally symmetric.   This theorem is philosophically motivated  both by the Alekseevskii Conjecture, which states that every homogeneous Einstein manifold of negative Ricci curvature is diffeomorphic to Euclidean space, and by the question of stability of Einstein metrics under the Ricci flow.   We also address questions of existence of maximally symmetric left-invariant Riemannian metrics more generally.  (This is joint work with Michael Jablonski.)

  1. Riemannian Geometry: Soap Bubbles, Spherical Metrics, and Quadratic Differentials

    Location: MSRI: Simons Auditorium
    Speakers: Rob Kusner (University of Massachusetts, Amherst)

    Complete embedded surfaces with constant mean curvature (CMC) are critical for area with an enclosed volume constraint. They model physical systems like soap bubbles or fluid jets.  After reviewing the geometry and moduli space theory for finite topology CMC surfaces, the special "coplanar" family will be explored using spherical metrics, complex projective structures and holomorphic quadratic differentials.
