关于非紧流形的eigenvalue界的注记

A note on eigenvalue bounds for non-compact manifolds

Matthias Keller, Shiping Liu, Norbert Peyerimhoff

摘要:

本文证明了严格负曲Cartan-Hadamard流形在本质谱以下的Laplace特征值$λ_k$的上界.我们的界限是根据$k^2$和具体的几何数据的流形。这也适用于截面曲率趋向于$-\infty$的非紧流形的特殊情况,其中由于唐纳利/李定理而不存在本质谱。结果站在鲜明的对比,拉普拉斯在图中,这样的界限一般不成立。

英文摘要:

In this article we prove upper bounds for the Laplace eigenvalues $λ_k$ below the essential spectrum for strictly negatively curved Cartan-Hadamard manifolds. Our bound is given in terms of $k^2$ and specific geometric data of the manifold. This applies also to the particular case of non-compact manifolds whose sectional curvature tends to $-\infty$, where no essential spectrum is present due to a theorem of Donnelly/Li. The result stands in clear contrast to Laplacians on graphs where such a bound fails to be true in general.
