          Compactness of bounded quasientropy solutions to the system 
          of equations of an isothermal gas
        The notion is introduced of quasientropy solution to the equations 
          of an isothermal gas in Lagrangian variables. Compactness of bounded 
          quasientropy solutions is established. Reduction of Young measures to 
          Dirac measures bases on group analysis for the entropy wave equation.
