Summary.
This paper is devoted to the study of a posteriori and a priori error estimates for the scalar nonlinear convection diffusion equation \(c_t + \nabla \cdot ( \u f(c)) - \varepsilon \Delta c = 0\). The estimates for the error between the exact solution and an upwind finite volume approximation to the solution are derived in the \(L^1\)-norm in the situation, where the diffusion parameter \(\varepsilon\) is smaller or comparable to the mesh size. Numerical experiments underline the theoretical results.
