In this work, we propose new sufficient conditions to solve the spectralpollution problem by using the generalized spectrum method. We give the theoretical foundation of the generalized spectral approach, as well as illustrate its effectivenessby numerical results.
Keywords: generalized spectrum, Schrodinger operator, eigenvalue approximation.
