Abstract
The theory of eigenvalues and eigenvectors of rectangular matrix penci ls is complicated by the fact that arbitrarily small perturbations of the pencil can cause them to disappear. However, there are application s in which the properties of the pencil ensure the existence of eigenv alues and eigenvectors. In this paper it is shown how to develop a per turbation theory for such pencils.
