Laplacian谱函数的C-无穷标度渐近性

C-infinity Scaling Asymptotics for the Spectral Function of the Laplacian

Yaiza Canzani, Boris Hanin

摘要:

本文研究紧致n维黎曼流形上逐点Weyl律中余项及其导数的新的非对角估计。作为应用,我们证明了在任意非自聚焦点附近,拉普拉斯算子的谱投影到常数大小的频率窗口上的标度极限是一个仅依赖于n的归一化贝塞尔函数.

英文摘要:

This article concerns new off-diagonal estimates on the remainder and its derivatives in the pointwise Weyl law on a compact n-dimensional Riemannian manifold. As an application, we prove that near any non self-focal point, the scaling limit of the spectral projector of the Laplacian onto frequency windows of constant size is a normalized Bessel function depending only on n.
