Christoph Böhm will talk on 19th October at 2pm UK time, 3pm Belgian time. Christoph’s title is “Non-compact Einstein manifolds with symmetry” and his abstract is below.
Non-compact Einstein manifolds with symmetry
For Einstein manifolds with negative scalar curvature admitting an isometric action of a Lie group G with compact, smooth orbit space, we show the following rigidity result:The nilradical N of G acts polarly and the N-orbits are locally isometric to a nilsoliton.Applications will be discussed. This is joint work with R. Lafuente.
