CONVERGENCE OF THE VISCOSITY METHOD FOR A NONSTRICTLY HYPERBOLIC SYSTEM
一个非严格双曲型方程组粘性逼近解的收敛性

A convergence theorem for the viscosity method applied to the following nonstrictly hyperbolic system is established. Convergence of a subsequence in the strong topology is proved without uniform estimates on the derivatives, by using the theory of compensated compactness and an analysis of progressing entrory waves.
