Lax-wendroff theorem

WebDer Satz von Lax-Wendroff besagt, dass, falls die numerischen Lösungen einer hyperbolischen Erhaltungsgleichung konvergieren, sie gegen eine schwache Lösung der Gleichung konvergieren. Es handelt sich dabei um eine Aussage aus der numerischen Mathematik, die nach Peter Lax und Burton Wendroff benannt ist. Satz [ Bearbeiten … WebTogether with Phillips, Lax developed a broad theory of scattering and described the long-term behaviour of solutions ( specifically, the decay of energy). Their work also turned out to be important in fields of mathematics apparently very distant from differential equations, such as number theory.
