• Barotropic gas
• Small oscillations
• Variational
• Operatorial and spectral methods

The authors study the problem of the small oscillations of a system viscous liquid- barotropic gas in a fixed container. From the equations of motion and using two auxiliary problems, they reduce the problem to a system of two operatorial equations in a suitable hilbertian space. By means of the methods of the functional analysis, they prove the existence of the spectrum and study its properties.
