Research output: Contribution to journalArticlepeer-review


In this paper, we introduce a new method for the standard finite element approximation in the L∞-norm of the semilinear quasi-variational inequality (QVI)
arising in impulse control theory. We derive the optimal L∞-error estimate by
means of the concept of subsolutions for QVIs
