摘要:Abstract(#br)We give various estimates of the first eigenvalue of the p -Laplace operator on closed Riemannian manifold with integral curvature conditions.

摘要:Abstract(#br)We obtain a local Sobolev constant estimate for integral Ricci curvature, which enables us to extend several important tools such as the maximal principle, the gradient estimate, the heat kernel estimate and the L 2 Hessian estimate to manifolds with integral Ricci l...

摘要:Abstract(#br)If X is the Gromov–Hausdorff limit of a sequence of Riemannian manifolds M i n with a uniform lower bound on Ricci curvature, Sormani and Wei have shown that the universal cover X ˜ of X exists [C. Sormani, G. Wei, Hausdorff convergence and universa...

摘要:Abstract(#br)We prove a Hitchin–Thorpe inequality for noncompact Einstein 4-manifolds with specified asymptotic geometry at infinity. The asymptotic geometry at infinity is either a cusp bundle over a compact space (the fibered cusps) or a fiber bundle over a cone with a com...

摘要:Abstract(#br)We call a metric quasi-Einstein if the m -Bakry–Emery Ricci tensor is a constant multiple of the metric tensor. This is a generalization of Einstein metrics, it contains gradient Ricci solitons and is also closely related to the construction of the warped produc...
