【 摘 要 】

Approximate symmetries of a mathematical model describing one-dimensional motion in a medium with a small nonlinear viscosity are studied. In a physical application, the approximate solution is calculated making use of the approximate generator of the first-order approximate symmetry. MSC:35J25, 32A37, 43A15, 35A58, 42B20.
