DESCRIPTION:Title: <a href="https://researchseminars.org/talk/VSGS/12/">Ho
 mogeneous Einstein metrics via a cohomogeneity-one approach</a>\nby Ramiro
  Lafuente (The University of Queensland) as part of Virtual seminar on geo
 metry with symmetries\n\n\nAbstract\nWe establish non-existence results on
  non-compact homogeneous Einstein manifolds. The key idea in the proof is 
 to consider non-transitive group actions on these spaces (more precisely\,
  actions with cohomogeneity one)\, and to find geometric monotone quantiti
 es for the ODE that results from writing the Einstein equation in such a s
 etting. As an application\, we show that homogeneous Einstein metrics on E
 uclidean spaces are Einstein solvmanifolds. This is joint work with C. Bö
 hm.\n
