Coefficients of the equations and initial conditions are periodical functions of the space variable. A multi-scale perturbation technique and integrating along characteristics are used to construct asymptotic series without secular members. The scheme of asymptotic integration is applied to analysis of oscillations of nonlinear non-homogeneous strings.</span></p>}, number={B}, journal={Lietuvos matematikos rinkinys}, author={Krylovas Aleksandras}, year={2016}, month={Dec.}, pages={31–36} }
