ABSTRACT: In this
article, we compute the enclosures eigenvalues (upper and lower bounds) using
the quadratic method. The Schrodinger operator (A) (harmonic and anharmonic
oscillator model) has used as an example. We study a new technique to get more accurate bounds. We
compare our results with Boulton and Strauss method.
