    Suppose (M,g)is a complete Hessian manifold with non-negative Ricci curvature. Ifρsatisfies_gρ=β(‖ρ‖_g~2)/ρ(β≠1), then x(M) must be an elliptic paraboloid.

    假设(M,g)是一完备的Hessian流形且具有非负的李奇曲率,如果ρ满足_gρ=β(‖_ρ‖_g~2/ρ)(β≠1),则M一定是椭圆抛物面。

Ricci curvature

  • abstract: In differential geometry, the Ricci curvature tensor, named after Gregorio Ricci-Curbastro, represents the amount by which the volume of a geodesic ball in a curved Riemannian manifold deviates from that of the standard ball in Euclidean space. As such, it provides one way of measuring the degree to which the geometry determined by a given Riemannian metric might differ from that of ordinary Euclidean n-space.
