On the convergence of quasilinear viscous approximations with BV initial data

Abstract

We show that the almost everywhere limit of quasilinear viscous approximations is the unique entropy solution (in the sense of {\it Bardos-Leroux-Nedelec}) of the corresponding scalar conservation laws on a bounded domain in ${\mathbb{R}}^d$ whenever the initial data is essentially bounded and a function of bounded variation.
