On Convergence of Minmod-type Schemes
Abstract
A class of non-oscillatory numerical methods for solving nonlinear scalar conservation laws in one space dimensions is considered. This class of methods contains the classical Lax-Friedrichs and the second order Nessyahu-Tadmor scheme. In the case of linear flux, new l2 stability results and error estimates for the methods are proved. Numerical experiments confirms that these methods are one-sided l2 stable for convex flux instead of the usual Lip+stability.
