| Abstract: | In this note, we answer positively a question by Belegradek and Kapovitch about the
relation between rational homotopy theory and a problem in Riemannian geometry which asks that
total spaces of which vector bundles over compact non–negative curved manifolds admit (complete)
metrics with non–negative curvature.
