Abstract: We describe necessary and sufficient conditions for a region in $ {{\mathbf{R}}^n}$ to be invariant for (Glimm) solutions of the system of $ n$ conservation laws $ {u_t} + f{(u)_x} = 0$. We also make some observations about the invariance of such regions for certain finite difference approximations of solutions of systems of conservation laws.
