L-infinity-error estimate for a system of elliptic quasi-variational inequalities with noncoercive operators
This paper deals with the finite element approximation of a system of elliptic quasivariational inequalities with noncoercive operators. A quasi-optimal L-infinity-error estimate is established using the concepts of L-infinity-stability and subsolution. (C) 2003 Elsevier Science Ltd. All rights reserved.
