Dirichlet到Neumann算子的谱渐近性

Spectral asymptotics for Dirichlet to Neumann operator

Victor Ivrii

摘要:

本文研究了Laplacian算子在带边区域(或流形)上的Dirichlet-to-Neumann算子的特征值,建立了特征值计数函数\begin{equation*} \mathsf{N}(λ)= κ_0λ^d +O(λ^{d-1})\qquad \text{as}\ \ λ\to+\infty, \end{equation*}的渐近性,其中$d$是边界维数.此外,在某些情况下,我们建立了两项渐近\begin{equation*} \mathsf{N}(λ)= κ_0λ^d+κ_1λ^{d-1}+o(λ^{d-1})\qquad \text{as}\ \ λ\to+\infty. \end{equation*}我们还建立了改进的Riesz平均渐近。

英文摘要:

We consider eigenvalues of the Dirichlet-to-Neumann operator for Laplacian in the domain (or manifold) with edges and establish the asymptotics of the eigenvalue counting function \begin{equation*} \mathsf{N}(λ)= κ_0λ^d +O(λ^{d-1})\qquad \text{as}\ \ λ\to+\infty, \end{equation*} where $d$ is dimension of the boundary. Further, in certain cases we establish two-term asymptotics \begin{equation*} \mathsf{N}(λ)= κ_0λ^d+κ_1λ^{d-1}+o(λ^{d-1})\qquad \text{as}\ \ λ\to+\infty. \end{equation*} We also establish improved asymptotics for Riesz means.
