Abstract

The results of solving the group classification problem of a universal nonlinear equation of one-dimensional gas flows with plane, cylindrical and spherical waves are presented. All specializations of the state equation are found when the main group is expanded. In particular, in the case of plane waves, in addition to the known ones, a polytropic gas with an adiabatic index of γ = 5 is released
