Title: Error bounds in the approximation of eigenvalues of differential and integral operators.
Author: Chatelin, Francois
Author: Lemordant, J.
Date: February 1975
Abstract: Various methods of approximating the eigenvalues and invariant subspaces of nonself-adjoint differential and integral operators are unified in a general theory. Error bounds are given, from which most of the error bounds in the literature can be derived.
