Для реализации разностной схемы использован итерационный процесс. Доказана сходимость итерационного процесса и устойчивость разностной схемы в случае начальных данных, гарантирующих отсутствие ударных волн. В случае возникновения ударных волн получены оценки роста пространственных производных на каждом временном слое. Построен адаптивный вычислительный алгоритм решения уравнения переноса при формировании ударных волн.</p></abstract><trans-abstract xml:lang="en"><p>In this paper, we investigate the stability with respect to initial data in the uniform norm of an implicit difference scheme approximating a nonlinear transport equation. An iterative process is used to implement the difference scheme. The convergence of the iterative process and the stability of the difference scheme are proven in the case of initial data guaranteeing the absence of shock waves. In the case of the occurrence of shock waves, estimates of the growth of spatial derivatives at each time layer are obtained. An adaptive computational algorithm for solving the transfer equation during the formation of shock waves is built.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>устойчивость</kwd><kwd>разностная схема</kwd><kwd>итерационный процесс</kwd><kwd>ударная волна</kwd></kwd-group><kwd-group xml:lang="en"><kwd>stability</kwd><kwd>difference scheme</kwd><kwd>iteration process</kwd><kwd>shock wave</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Самарский, А.
