The Smoothness of Riemannian Submersions with Nonnegative Sectional Curvature
In this article, we study the smoothness of Riemannian submersions for open manifolds with non-negative sectional curvature. Suppose thatM is a C-smooth, complete and non-compact Riemannian manifold with nonnegative sectional curvature. Cheeger-Gromoll [ChG] established a fundamental theory for such a manifold. Among other things, they showed that M admits a totally convex exhaustion {Ωu}u≥0 of...
متن کاملThe Dual Foliation in Open Manifolds with Nonnegative Sectional Curvature
We study several properties of the Sharafutdinov dual foliation in open manifolds with nonnegative sectional curvature.
متن کاملRemark about Scalar Curvature and Riemannian Submersions
We consider modified scalar curvature functions for Riemannian manifolds equipped with smooth measures. Given a Riemannian submersion whose fiber transport is measure-preserving up to constants, we show that the modified scalar curvature of the base is bounded below in terms of the scalar curvatures of the total space and fibers. We give an application concerning scalar curvatures of smooth lim...
متن کاملPontryagin Numbers and Nonnegative Curvature
We prove that any rational linear combination of Pontryagin numbers that is not a multiple of the signature is unbounded on connected closed oriented manifolds of nonnegative sectional curvature. Combining our result with Gromov’s finiteness result for the signature yields a new characterization of the L-genus.
متن کاملComplete Manifolds of Nonnegative Curvature
The purpose of this survey is to give an overview of the results which characterize Riemannian manifolds with nonnegative or positive sectional, Ricci and scalar curvature, putting an emphasis on the differences between these increasingly strong conditions on curvature. All manifolds considered here are assumed to be complete. First we consider how nonnegative curvature is different from positi...
