Averaged multivalued solutions for scalar conservation laws. (English) Zbl 0565.65054
A time discretization for scalar conservation laws which consists in averaging the generally multivalued solution constructed by the classical method of characteristics is proposed and its convergence toward the solution satisfying the entropy condition is proved. On this base several numerical schemes are deduced and some generalizations toward systems of conservation laws and bidimensional scalar conservation laws are considered.
