有界区域上Neumann问题的特征值估计

Eigenvalues estimate for the Neumann problem on bounded domains

Bruno Colbois, Daniel Maerten

摘要:

本文研究了在给定的完备(非紧的先验)黎曼流形中具有光滑边界的有界区域的Laplacian的Neumann本征值问题的上界.为此,我们使用检验函数的瑞利商从属于一个家庭的开集构造在一个一般的度量的方式,有趣的本身。作为应用,我们得到了Neumann谱的上界,该上界与Weyl定律一致,并类似于Buser关于闭黎曼流形的谱的上界,其下界在里奇曲率上.

英文摘要:

In this note, we investigate upper bounds of the Neumann eigenvalue problem for the Laplacian of a bounded domain (with smooth boundary) in a given complete (not compact a priori) Riemannian manifold with Ricci bounded below . For this, we use test functions for the Rayleigh quotient subordinated to a family of open sets constructed in a general metric way, interesting for itself. As application, we get upper bounds for the Neumann spectrum which is clearly in agreement with the Weyl law and which is analogous to Buser's upper bounds of the spectrum of a closed Riemannian manifold with lower bound on the Ricci curvature.
