摘要
This paper is an extension for our previous results [3-5], and it deals with the finite element approximation of a parabolic quasivariational inequalities with mixed boundary conditions. A quasi-optimal L infinity-error estimate is established using a new discrete algorithm stands in theta time scheme combined with a finite element spatial approximation. Our approach stands on a discrete L infinity-stability property with respect to the right-hand side where the obstacle defined as an impulse control problem. (C) 2013 Taibah University.
