Generalizations of isoparametric foliations
Abstract
Description
Isoparametric submanifolds and hypersurfaces in space forms are geometric objects that have been studied since E. Cartan. Another important class of geometric objects is the orbits of a polar action on a Riemannian manifold,e.g., the orbits of the adjoint action of a Lie group on itself. These two classes of submanifolds share comon properties. For example, they are leaves of a singular Riemannian foliation with sections (s.r.f.s. for short). The purpose of this paper is to review some results of the theory of s.r.f.s., which have been developed by the author. In addition, we give an alternative proof of Toeben's Theorem, who gave a necessary and sufficient condition for an equifocal submanifold to induce a s.r.f.s.
