Abstract

Description

A new approach proposed recently by author for the calculation of Green functions in quantum field theory and quantum mechanics is briefly reviewed. The method is applied to nonperturbative calculations for anharmonic oscillator, $ϕ^4$-theory, quantum electrodynamics and other models.
