Bounded Riemannian submersions

Indiana University Mathematics Journal, 2000
The paper studies some global metric properties of a Riemannian submersion on a compact manifold for which the fundamental tensors are bounded in norm. A motivation is given by a result of \textit{G. Perelman} [J. Differ. Geom. 40, 209-212 (1994; Zbl 0818.53056)], who proved that the metric projection of an open manifold of nonnegative sectional ...

Integrable Riemannian Submersion with Singularities

Geometriae Dedicata, 2004
It is proven that regular level sets of an analytic transnormal map on a real analytic complete Riemannian manifold are equifocal submanifolds and leaves of a singular Riemannian foliation with sections. Equifocal submanifolds are generalizations of isoparametric submanifolds and isoparametric hypersurfaces.

A Metric Characterization of Riemannian Submersions

Annals of Global Analysis and Geometry, 2000
According to the first author [Sib. Math. J. 28, No. 4, 552-562 (1987; Zbl 0643.53053); translation from Sib. Mat. Zh. 28, No. 4(164), 44-56 (1987)], a map between metric spaces is a submetry if it sends closed balls around a point to closed balls of the same radius, around the image point.

Redundant Robotic Chains on Riemannian Submersions

IEEE Transactions on Robotics and Automation, 2004
The paper introduces the notion of Riemannian submersion for the modeling and control of certain types of redundant robotic chains. In the robotics literature, the redundant case is normally treated only in numerical terms, as the need to resort to pseudoinversion techniques is usually considered a barrier to the use of analytic or geometric methods ...
