我们研究了有界域上的-Neumann Laplace算子在基础区域被扰动时的谱稳定性。特别地,我们建立了文[1]中有界伪凸域上的-Neumann Laplace算子的变分特征值的上半连续性,满足性质(P)的伪凸域上的下半连续性,以及文[1]中有限D‘Angelo型光滑有界伪凸域上的定量估计。
We study spectral stability of the-Neumann Laplacian on a bounded domain inwhen the underlying domain is perturbed. In particular, we establish upper semi-continuity properties for the variational eigenvalues of the-Neumann Laplacian on bounded pseudoconvex domains in, lower semi-continuity properties on pseudoconvex domains that satisfy property (P), and quantitative estimates on smooth bounded pseudoconvex domains of finite D’Angelo type in.
