A note on the Ricci flow on noncompact manifolds
Hong Huang
Let be a complete noncompact Riemannian 3-manifold with nonnegative Ricci curvature and with injectivity radius bounded away from zero. Suppose that the scalar curvatur…
A note on Khler manifolds with almost nonnegative bisectional curvature
Hong Huang
In this note we prove the following result: There is a positive constant such that if is a simply connected compact Khler manifold with sectional curvature…
The advanced maximum principle for parabolic systems on manifolds with boundary
Hong Huang
In this short note we extend Chow and Lu's advanced maximum principles for parabolic systems on closed manifolds to the case of compact manifolds with boundary, which also generali…
A remark on odd dimensional normalized Ricci flow
Hong Huang
Let ( odd) be a compact Riemannian manifold with , where is the first eigenvalue of the operator , and is the scalar cu…
Some gradient estimates for a diffusion equation on Riemannian manifolds
Hong Huang
In this note we present some gradient estimates for the diffusion equation on Riemannian manifolds, where is a C^2 function, which gen…
