In order to model phenomena arising in matter flows in electromagnetic fields, engineers join systems of conservation laws with discontinuous coefficients. The simplest quasi-linear equation is u t + a f u x = 0, where a is a given discontinuous coefficient function and f is a smooth function. We be

β¦ Synopsis
We prove L 1 contractivity of weak solutions to a conservation law with a flux function that may depend discontinuously on the space variable. Furthermore, we show that the L 1 difference between solutions to conservation laws with different flux functions is bounded by the total variation with respect to the space variable, of the difference between the flux functions.

We consider systems of conservation laws and give conditions for nonlinear stability of viscous shock profiles. The analysis applies to classical shocks of arbitrary strength.
## Abstract For the scalar conservation laws with discontinuous flux, an infinite family of (__A, B__)βinterface entropies are introduced and each one of them is shown to form an __L__^1^βcontraction semigroup (see [2]). One of the main unsettled questions concerning conservation law with discontin
