abstract = {<p style="text-align: justify;">It is proven that in dimension one the piecewise linear best $L^1$-approximation to the linear transport equation equipped with a set
of ill-posed boundary conditions converges in $W_{loc}^{1,1}$ to the
viscosity solution of the equation and the boundary layer associated
with the ill-posed boundary condition is always localized in one mesh
cell, i.e., the &quot;last&quot; one.</p>},
