## Convergence of the viscosity method for isentropic gas dynamics.(English)Zbl 0533.76071

In this paper a convergence theorem for the method of artificial viscosity applied to the isentropic equations of gas dynamics is established. The author is concerned with the zero diffusion limit of hyperbolic systems of conservation laws. One natural strategy for proving convergence as the diffusion parameter vanishes is to look for uniform estimates on the amplitude and the derivatives of the approximate solutions and then appeal to a compactness argument in order to extract a strongly convergent subsequence.
