Group properties of 2-submodels for the evolutionary class of gas-dynamic equations (English)
0 references
Invariant 2-submodels (submodels with two independent variables) of the evolutionary class are considered for the equations of gas dynamics with an equation of state of general form. Group analysis of these submodels is performed. Allowable operators as well as transformations of equivalence are indicated and group classification is performed.
