DESCRIPTION:Title: <a href="https://researchseminars.org/talk/VSGS/37/">No
 n-compact Einstein manifolds with symmetry</a>\nby Christoph Böhm (Univer
 sity of Münster) as part of Virtual seminar on geometry with symmetries\n
 \n\nAbstract\nFor Einstein manifolds with negative scalar curvature admitt
 ing an isometric action\nof a Lie group $G$ with compact\, smooth orbit sp
 ace\, we show the following rigidity result: The\nnilradical $N$ of $G$ ac
 ts polarly\, and the $N$-orbits can be extended to minimal Einstein subman
 ifolds.\n\nAs an application\, we prove the Alekseevskii conjecture. This 
 is joint work with R. Lafuente.\n
