Abstract
In the given work using of method of shortening according to independent variable change and getting of effective estimation of deflection almost multiperiodical solution of basic and shortened systems is studied. Object: to prove new estimation for characteristic functions integrodifferential operator and matrix of linear system. To investigate stability almost multiperiodical solutions of evolutional sums. The results of the work introduce theoretical interest. They can be used in further research of oscillating limited solutions of integrodifferential equations in particular derivatives of the first order with a number of independent variables. These results will be also useful while studying periodical solutions of evolutional equations of mathematical physics. In the theory of oscillates great theoretical and practical meaning has studying of single measured and multi measured periodical of oscillates.
