Abstract
Systems of conservation laws admitting an entropy obtain from a simple variational principle. This approach leads to a simplified treatment of a symmetry group for such systems, and to a simplified proof of the equivalence of systems obtained by a change of coordinates. The case of systems which are hyperbolic, in the sense of a convex extensions, is identified with local extremum values of corresponding functionals.
