Benjamin – Bona – Mahony equation with variable coefficients}, volume={70}, url={http://umj.imath.kiev.ua/index.php/umj/article/view/1554}, abstractNote={We study the problem of construction of asymptotic $\Sigma$ -solutions to the singularly perturbed Benjamin – Bona – Mahony equation with variable coefficients. An algorithm for the construction of solutions is described. We determine main and
first terms of the asymptotic solution. The theorems on the accuracy with which the indicated asymptotic solution satisfies
the considered equation are also proved.}, number={2}, journal={Ukrains’kyi Matematychnyi Zhurnal}, author={Samoilenko, V. G. and Samoilenko, Yu. I.}, year={2018}, month={Feb.}, pages={236-254} }
