Lax–Wendroff theorem

The Lax-Wendroff theorem is a fundamental result in the field of numerical analysis, specifically concerning the stability and convergence of finite difference methods for solving hyperbolic partial differential equations (PDEs). It was established by Peter D. Lax and Boris Wendroff in their 1960 paper. The theorem provides criteria under which a finite difference scheme will be both consistent and stable, leading to convergence to a weak solution of the underlying hyperbolic PDE.
