On calculation of evolution operator kernel of Schroedinger equation
Description
A method for calculation of the evolution operator kernel as an expansion in powers of the time interval Δt is proposed. This method can be applied to the problems of quantum mechanics and quantum field theory with polynomial potentials. Nonperturbative (in coupling constant) effects can be considered in the framework of this approach. (orig.)
