This paper is dedicated to the classical Hadamard formula for asymptotics of eigenvalues of the Dirichlet-Laplacian under perturbations of the boundary. We prove that the Hadamard formula still holds for C1-domains with C1-perturbations. We also derive an optimal estimate for the remainder term in the C1,α-case. Furthermore, if the boundary is merely Lipschitz, we show that the Hadamard formula is not valid.

Dirichlet Laplacian特征值的Hadamard渐近性

本文致力于边界扰动下Dirichlet-Laplacian特征值渐近性的经典Hadamard公式。我们证明哈达玛公式仍然适用于C1个-个域 C1个-摄动。我们还得出了剩余项中的最优估计C1个α-案件。此外,如果边界仅是Lipschitz,则表明Hadamard公式无效。
