摘要

在非空边界紧黎曼流形上证明了微分形式的一个新的一般poincar型不等式。当边界等距浸入欧几里德空间时，我们导出了一个只涉及边界的平均曲率和标量曲率的不等式，并刻画了它在余维1上的极限情况。在流形上存在非零平行形式的前提下，导出了微分形式下的一个新的ros型不等式。

A Poincaré Formula for Differential Forms and Applications

We prove a new general Poincaré-type inequality for differential forms on compact Riemannian manifolds with nonempty boundary. When the boundary is isometrically immersed in Euclidean space, we derive a new inequality involving mean and scalar curvatures of the boundary only and characterize its limiting case in codimension one. A new Ros-type inequality for differential forms is also derived assuming the existence of a nonzero parallel form on the manifold.
