DESCRIPTION:Title: <a href="https://researchseminars.org/talk/VSGS/62/">To
 tally geodesic submanifolds in exceptional symmetric spaces</a>\nby Andrea
 s Kollross (University of Stuttgart) as part of Virtual seminar on geometr
 y with symmetries\n\n\nAbstract\nJoint work with Alberto Rodríguez-Vázqu
 ez. I will speak about our recent paper where we classify maximal totally 
 geodesic subspaces in exceptional Riemannian symmetric spaces. Since the m
 aximal subspaces containing flat factors have been classified by Berndt an
 d Olmos\, it suffices to find the semisimple ones. We show that these corr
 espond to subalgebras in the Lie algebra of the isometry group which are m
 aximal among the semisimple subalgebras without compact ideals. To find al
 l such subalgebras of simple real Lie algebras\, we use earlier classifica
 tion results by Dynkin\, de Graaf-Marrani and Komrakov.\n
