In this paper we study spectral stability of the \(\bar{\partial }\)-Neumann Laplacian under the Kohn–Nirenberg elliptic regularization. We obtain quantitative estimates for stability of the spectrum of the \(\bar{\partial }\)-Neumann Laplacian when either the operator or the underlying domain is perturbed.

$$ {\ overline {\ partial}} $$∂的谱稳定性-Neumann Laplacian:Kohn-Nirenberg椭圆正则化

在本文中,我们研究了Kohn–Nirenberg椭圆正则化条件下\(\ bar {\ partial} \)- Neumann Laplacian的光谱稳定性。当算子或基础域受到扰动时,我们获得\(\ bar {\ partial} \)- Neumann Laplacian谱的稳定性的定量估计。
