چکیده
There is a conjecture that complete Riemannian 3-manifold with bounded sectional curvature, and pointwise pinched nonnegative Ricci must be flat or compact. We show this true when the negative part (if any) of curvature decays quadratically.

Manifolds with Pointwise 1/4-pinched Curvature
In this lecture we will describe our recent joint work with SimonBrendle ([1], [2]) in which we give the differentiable classification ofcompact Riemannian manifolds with pointwise 1/4-pinched curvature.Our theorems are:Theorem 1. Let M be a compact Riemannian manifold with pointwise1/4-pinched curvature. Then M admits a metric of constant curvature,and therefore is ...
متن کاملConformally Flat Manifolds with Nonnegative Ricci Curvature
We show that complete conformally flat manifolds of dimension n > 3 with nonnegative Ricci curvature enjoy nice rigidity properties: they are either flat, or locally isometric to a product of a sphere and a line, or are globally conformally equivalent to R n or a spherical spaceform Sn/Γ. This extends previous results due to Q.-M. Cheng and B.-L. Chen and X.-P. Zhu. In this note, we study compl...
متن کاملBoundary Convexity on Manifolds with Nonnegative Ricci Curvature
We introduce a new geometric invariant Λ to measure the convexity of the boundary of a riemannian manifold with nonnegative Ricci curvature in the interior. Based on a theorem of Perelman, we are able to show that this new invariant has topological implications. More specifically, we show that if Λ is close to 1 and the sectional curvature is positive on the boundary, then the manifold is contr...
متن کاملTopology of Manifolds with Asymptotically Nonnegative Ricci Curvature
In this paper, we study the topology of complete noncompact Riemannian manifolds with asymptotically nonnegative Ricci curvature. We show that a complete noncompact manifold with asymptoticaly nonnegative Ricci curvature and sectional curvature KM (x) ≥ − C dp(x) is diffeomorphic to a Euclidean n-space R under some conditions on the density of rays starting from the base point p or on the volum...
متن کاملRigidity of Compact Manifolds with Boundary and Nonnegative Ricci Curvature
Let Ω be an (n + 1)-dimensional compact Riemannian manifold with nonnegative Ricci curvature and nonempty boundary M = ∂Ω. Assume that the principal curvatures of M are bounded from below by a positive constant c. In this paper, we prove that the first nonzero eigenvalue λ1 of the Laplacian of M acting on functions on M satisfies λ1 ≥ nc2 with equality holding if and only if Ω is isometric to a...
