In this paper the problem of quantization of the free gravitational field on classical background (the exact solutions of Einstein equations) is considered. The Bogoliubov group coordinates method in path integral formalism is developed. This approac

Doubly periodic (periodic both in time and in space) solutions for the Lagrange-Euler equation of the (1+1)-dimensional scalar Phi^4 theory are considered. The nonlinear term is assumed to be small, and the Poincare-Lindstedt method is used to find a

The existence of double-periodic solutions in the one-dimensional (1+1) ϗ4-model is shown numerically, and the dispersion law for the corresponding nonlinear waves is found.

Double-periodic solutions of the Euler-Lagrange equation for the (1+1)-dimensional scalarϗ4-theory are considered. The nonlinear term is assumed to be small, and the Poincare method is used to seek asymptotic solutions in the standing-wave form. The

We continue our analysis of relativistically invariant systems and perform the reduction of the number of field states. Expressions for the integrals of motion are given in the zeroth order in the inverse powers of the coupling constant in the form o

We define the Bogoliubov variables for strongly coupled systems that are invariant under the Poincare group in (1+1)-dimensional space-time. This allows us to achieve a compatibility between taking the conservation laws into account exactly and devel

For the example of a field quantized for positive values of the spatial coordinate (when particle creation certainly cannot occur) it is shown that incorrect use of the formula for the creation and annihilation operators leads to a transformation fro
