Sphere theorem through ricci flow
Web11. feb 2011 · Some new differentiable sphere theorems are obtained via the Ricci flow and stable currents. We prove that if is a compact manifold whose normalized scalar curvature and sectional curvature satisfy the pointwise pinching condition , where is an explicit positive constant, then is diffeomorphic to a spherical space form.
