Title: Vanishing non-local regularization of a scalar conservation law Author: Jerome Droniou (Universite Montpellier II, France) Abstract: We prove that the solution to the regularization of a scalar conservation law by a fractional power of the Laplacian converges, as the regularization vanishes, to the entropy solution of the hyperbolic problem. We also give an error estimate when the initial condition has bounded variation. Submitted October 22, 2003. Published November 28, 2003. Math Subject Classifications: 35L65, 35A35, 35B20.
