关于differential forms的一个Reilly公式和eigenvalue估计

A Reilly formula and eigenvalue estimates for differential forms

Simon Raulot, Alessandro Savo

摘要:

本文导出了紧致带边流形上微分p-形式的Reilly型公式,并应用它给出了作用在黎曼流形的嵌入超曲面的微分形式上的Hodge Laplacian的谱的一个精确下界.我们的不等式的平等情况下,产生了一些刚性的结果,当边界的几何形状有特殊的属性和域是非负弯曲。最后,我们还得到,作为我们的计算的副产品,一个上界的霍奇拉普拉斯算子的第一特征值时,周围的流形支持非平凡的平行形式。

英文摘要:

We derive a Reilly-type formula for differential p-forms on a compact manifold with boundary and apply it to give a sharp lower bound of the spectrum of the Hodge Laplacian acting on differential forms of an embedded hypersurface of a Riemannian manifold. The equality case of our inequality gives rise to a number of rigidity results, when the geometry of the boundary has special properties and the domain is non-negatively curved. Finally we also obtain, as a by-product of our calculations, an upper bound of the first eigenvalue of the Hodge Laplacian when the ambient manifold supports non-trivial parallel forms.
