In this paper, we study geometric and topological properties of vector fields on Riemannian manifolds of constant and nonnegative curvature, including Killing vector fields. We construct a completely integrable family of vector fields such that its orbits form a foliation whose set of singular fibers consists of two circles and regular fibers are two-dimensional tori. The solenoidal character of Killing vector fields on three-dimensional Euclidean space is also proved.
Keywords: vector field, Killing vector field, roughness of vector fields.
