Boundary layers in parabolic perturbations of scalar conservation laws

Keywords: Conservation laws | parabolic equations | boundary layers

We consider the problem of estimating the boundary layer thickness for vanishing viscosity solutions of boundary value problems for parabolic perturbations of a scalar conservation law in a space strip in $\mathbb{R}^d$. For the boundary layer thickness $\delta(\epsilon)$ we obtain that one can take $\delta(\epsilon)=\epsilon^r$, for any $r<1/2$, arbitrarily close to $1/2$.
