The global weak entropy solution of nonconvex scalar conservation laws in finite interval. (Chinese. English summary) Zbl 1150.35484
Summary: By using polygonal approximations method, the global approximation solution is constructed for the initial-boundary value problem of non-convex scalar conservation laws in finite interval, and its convergence to the global weak entropy solution of corresponding initial-boundary value problem is proved in this paper.
