Abstract
A nonperturbative method is suggested for calculating functional integrals. Its efficiency is demonstrated for the quantum-mechanical anharmonic oscillator. A quantity we are interested in is represented by a series, a finite number of terms of which describes not only the region of small coupling constants but well reproduces the strong coupling limit. The method is formulated only in terms of the Gaussian functional quadratures and diagrams are used of the conventional perturbation theory.
