The smoothness of Riemannian submersions with non-negative sectional curvature
, 2008 Let M n be a complete, non-compact and C ∞-smooth Riemannian manifold with nonnegative sectional curvature. Suppose that S is a soul of M n given by the fundamental theory of Cheeger and Gromoll, and suppose that Ψ: M n → S is a distance nonincreasing ...
