Boulbrachene, Messaoud \(L^\infty\)-error estimate for a noncoercive system of elliptic quasi-variational inequalities: a simple proof. (English) Zbl 1123.35322 Appl. Math. E-Notes 5, 97-102 (2005). Summary: we provide a simple proof to derive an \(L^ \infty\)-error estimate for a noncoercive system of quasi-variational inequalities related to the management of energy production. The key idea is a discrete \(L^ \infty\)-stability property owned by the corresponding coercive problem.
