We define and evaluate the normwise backward error and condition numbers for the multiparameter eigenvalue problem (MEP). The pseudospectrum for the MEP is defined and characterized. We show that the distance from a right definite MEP to the closest non right definite MEP is related to the smallest

In this paper we consider some types of second-order elliptic eigenvalue problems (EVPs) for vector valued functions on a convex polygonal domain in the plane, with nonstandard boundary conditions (BCs) of nonlocal type. The aim of the paper is twofold. First, we pass to a variational form of the EV
