DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GeoSem/20/">
 On the stability of compact homogeneous Einstein manifolds</a>\nby Jorge L
 auret (Universidad Nacional de Córdoba) as part of Geometry Seminar - Uni
 versity of Florence\n\n\nAbstract\nAfter some quick preliminaries on the g
 eneral stability theory of compact Einstein manifolds\, we will focus on t
 he homogeneous case and give a formula for the Lichnerowicz Laplacian of a
  G-invariant metric on a compact homogeneous space M=G/K\, restricted to t
 he subspace of G-invariant TT-tensors\, which was obtained via the moving 
 bracket approach.  \n\nAs an application\, we study the stability type of 
 G-invariant Einstein metrics on M\, which are known to be the critical poi
 nts of the scalar curvature restricted to unit volume G-invariant metrics.
   The naturally reductive case presents some advantages.   \n\nThis is joi
 nt work with Cynthia Will and Emilio Lauret.\n
