Stefanov, P. D. Stability of resonances under smooth perturbations of the boundary. (English) Zbl 0814.35022 Asymptotic Anal. 9, No. 3, 291-296 (1994). Summary: We prove that the resonances related to a second order elliptic differential operator with Dirichlet boundary conditions are stable in each compact of the complex plane under small \(C^ 2\)-perturbations of the boundary and small changes of the coefficients.
