The explicit difference schemes for the constant-wind-speed advection equation, especially the Lax-Wendroff second-order method, have been commonly dealt with in the recent 50 years—there are many books and papers easily found in the literature concerning the numerical methods for hyperbolic partial differential …
WebIn this paper, it is proved that an a priori estimate weaker than a BV estimate is sufficient. The method of proof is based on the result of uniqueness given by Di Perna in the class of measure-valued solutions. Several general theorems of convergence are given in the spirit of the Lax–Wendroff theorem.
