$\mathcal{K}-$convergence as a new tool in numerical analysis

Numerical Analysis 2019-04-02 v1

Abstract

We adapt the concept of K\mathcal{K}-convergence of Young measures to the sequences of approximate solutions resulting from numerical schemes. We obtain new results on pointwise convergence of numerical solutions in the case when solutions of the limit continuous problem possess minimal regularity. We apply the abstract theory to a finite volume method for the isentropic Euler system describing the motion of a compressible inviscid fluid. The result can be seen as a nonlinear version of the fundamental Lax equivalence theorem.
