Résumé
We consider in this paper the linear stability problem of an isentropic, one-dimensional flow of a perfect fluid. In particular, we investigate the stability of the simple rarefaction and compression wave. We prove the instability of the compression wave when dissipative effects are disregarded. We follow the method formerly established by one of us and Prigogine on the stability of non equilibrium states (Physica 46, 344, 1970). The example treated, belongs to the class of time dependent stability problems.
