A supraconvergent scheme for nonlinear hyperbolic systems. (English) Zbl 0683.65078

It is shown that supraconvergence holds on a completely arbitrary one- dimensional grid for a cell-centered Lax-Wendroff (L-W) type scheme requiring the computation of the Jacobian. A computation which shows that second order accuracy fails in some cases in which the Jacobian predictor L-W method remains supraconvergent is presented for the standard L-W method.
