About Averaging in Hyperbolic Equation under the Influence of Multifrequence Disturbances

Abstract

The research deals with the existence of thesolution of the initial problem for hyperbolic equation under themultifrequency disturbances, which are described by the systemof ordinary differential equations (ODE) with multipoint andintegral conditions. The averaging method over fast variables isgrounded and estimation of accuracy of the method whichobviously depends on the small parameter was found.
