Abstract: Bogoliubov group variables are defined for the Poincare-invariant systems with a strong coupling in the $(1+1)$-dimensional space-time that makes possible to combine accurate account of conservation laws with perturbation theory. In terms of Bogoliubov group variables secondary quantization is prosecuted and the problem of states number reduction is considered. The condition of applicability of perturbation theory is discussed.
