# Invariant regions under Lax-Friedrichs scheme for multidimensional systems of conservation laws

• We establish necessary and sufficient conditions for the invariance of a region in the state space, under the Lax-Friedrichs scheme applied to a multidimensional system of conservation laws. We also give some examples of application of the invariance principle proved here.
