Symmetry analysis and new partially invariant solutions for the gas dynamics system with a special equation of state
Dilara Siraeva, Irina A. Kogan
This paper is a contribution to the symmetry analysis of the gas dynamics system in the vein of the ''podmodeli'' (submodels) program outlined by Ovsyannikov (1994). We consider th…

Partially invariant solution with an arbitrary surface of blow-up for the gas dynamics equations admitting pressure translation
Dilara Siraeva
We applied a method of symmetry reduction to the gas dynamics equations with a special form of the equation of state. This equation of state is a pressure represented as the sum of…
