Abstract
A nonperturbative method for calculating functional integrals is propo sed. Only Gaussian quadratures and only those types of diagrams which occur in the standard perturbation theory are used for the formulation of this method. The proposed approach is used for the consideration o f the psi2k anharmonic oscillator in the strong coupling limit.
