Abstract

Abstract This paper considers a number of related problems concerning the computation of eigenvalues and complex resonances of a general self-adjoint operator H . The feature which ties the different sections together is that one restricts oneself to spectral properties of H which can be proved by using only vectors from a pre-assigned (possibly finite-dimensional) linear subspace L .
