Perturbation determinants in Banach spaces - with an application to eigenvalue estimates for perturbed operators

Marcel Hansmann

In the first part of this paper we provide a self-contained introduction to (regularized) perturbation determinants for operators in Banach spaces. In the second part, we use these…
