Polar actions on symmetric spaces of higher rank

Andreas Kollross, Alexander Lytchak

We show that polar actions of cohomogeneity two on simple compact Lie groups of higher rank, endowed with a biinvariant Riemannian metric, are hyperpolar. Combining this with a rec…

Duality of symmetric spaces and polar actions

Andreas Kollross

We study isometric actions on Riemannian symmetric spaces of noncompact type which are induced by reductive algebraic subgroups of the isometry group. We show that for such an acti…
