Four-manifolds with 1/4-pinched flag curvatures
Andrews, Benjamin; Nguyen, Huy
Description
The Ricci flow on a compact four-manifold preserves the condition of pointwise 1/4-pinching of flag curvatures. Any compact Riemannian four-manifold with 1/4-pinched flag curvatures is either isometric to CP2 or diffeomorphic to a space-form.
