A general convergence result for the Ricci flow in higher dimensions
Abstract
Let (M,g0) be a compact Riemannian manifold of dimension n ≥ 4. We show that the normalized Ricci flow deforms g0 to a constant curvature metric provided that (M,g0) x R has positive isotropic curvature. This condition is stronger than 2-positive flag curvature but weaker than 2-positive curvature operator.
