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 ...

Harmonic proper almost complex structures on Walker 4-manifolds

, 2014
Every Walker 4-manifold M, endowed with a canonical neutral metric, admits a specific almost complex structure called proper. In this note we find the conditions under which a proper almost complex structure is harmonic in the sense of C.
