Abstract:

We consider the dependence of the entropic solution of a hyperbolic system of conservation laws \[ \left \{ \begin {array}{c} u_t + f(u)_x = 0, u(0,\cdot ) = u_0 \end {array} \right . \] on the flux function $f$. We prove that the solution is Lipschitz continuous w.r.t. the $C^0$ norm of the derivative of the perturbation of $f$. We apply this result to prove the convergence of the solution of the relativistic Euler equation to the classical limit.
