  1. Riemannian Geometry: Stable fixed points of the Einstein flow with positive cosmological constant

    Location: MSRI: Simons Auditorium
    Speakers: Klaus Kroencke (Universität Hamburg)

    We prove nonlinear stability for a large class of solutions to the Einstein equations with a positive cosmological constant and compact spatial topology in arbitrary dimensions, where the spatial metric is Einstein with either positive or negative Einstein constant. The proof uses the CMC Einstein flow and stability follows by an energy argument. We prove in addition that the development of non-CMC initial data close to the background contains a CMC hypersurface, which in turn implies that stability holds for arbitrary perturbations. This is joint work with David Fajman.

  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.)
