Corrigendum to “A numerically efficient and conservative model for a Riesz space-fractional Klein–Gordon–Zakharov system”

Abstract

In the article [Commun Nonlinear Sci Numer Simul 2019;71:22–37], the authors provided an erroneous proof for the existence of solutions of a finite-difference model for a fractional Klein–Gordon–Zakharov equation. This letter is intended to provide a correct proof of that theorem.
