Perturbations of isolated eigenvalues [PDF]

Rendiconti del Circolo Matematico di Palermo, 2000
In this paper, we generalize the result given by A. A. Dezin in [1] to the case of operators defined on a Banach space, under slightly different hypothesis. In the first part we consider perturbations of isolated simple eigenvalues, and in the second part we deal with perturbations of isolated multiple eigenvalues.

Perturbation of eigenvalues embedded at a threshold

Proceedings of the Royal Society of Edinburgh: Section A Mathematics, 2002
Results are obtained on perturbation of eigenvalues and half-bound states (zero-resonances) embedded at a threshold. The results are obtained in a two-channel framework for small off-diagonal perturbations. The results are based on given asymptotic expansions of the component Hamiltonians.
