Abstract

In this paper we prove a nonautonomous chain rule formula for the distributional divergence of the composite function \boldsymbolv(x)=\boldsymbolB(x,u(x)), where \boldsymbolB(⋅,t) is a divergence--measure vector field and u is a function of bounded variation. As an application, we prove a uniqueness result for scalar conservation laws with discontinuous flux.
