摘要：

In this paper, we investigate the L-infinity-error estimates for the solutions of general optimal control problem by mixed finite element methods. The state and co-state are approximated by the lowest order Raviart-Thomas mixed finite element spaces and the control is approximated by piecewise constant functions. We derive L-infinity-error estimates of optimal order both for the state variables and the control variable.
