A visible action on a complex manifold is a holomorphic action that admits a J-transversal
totally real submanifold S. It is said to be strongly visible if there exists an orbit-preserving …

We give a complete proof of a propagation theorem of multiplicity-free property from fibers to
spaces of global sections for holomorphic vector bundles. The propagation theorem is …

We study isometric Lie group actions on symmetric spaces admitting a section, ie, a
submanifold that meets all orbits orthogonally at every intersection point. We classify such …

These are the notes for a series of lectures at the Institute of Geometry and Topology of the
University of Stuttgart, Germany, in July 13-15, 2022. We assume basic knowledge of …

We show that polar actions of cohomogeneity 2 on simple compact Lie groups of higher
rank, endowed with a biinvariant Riemannian metric, are hyperpolar. Combining this with a …

We classify totally geodesic submanifolds of the real Stiefel manifolds of orthogonal two-
frames. We also classify polar actions on these Stiefel manifolds, specifically, we prove that …
