Parabolic subgroups of semisimple Lie groups and submanifold geometry
$B!V(BLie Groups: Geometry and Analysis$B!W(B
The solvable parts of parabolic subgroups of semisimple Lie groups
provide a rich sources of geometry of noncompact Riemannian homogeneous manifolds,
both intrinsically and extrinsically.
In this talk, I will mention that they provide many examples of
homogeneous hypersurfaces in symmetric spaces of noncompact type,
and polar actions on symmetric spaces of noncompact type.
