Kurzfassung englisch:
For discrete solutions to explicit ODE systems, it is well understood how to construct asymptotically correct a-posteriori error estimators by evaluating the defect in an appropriate way and solving a corrector equation. In the case of implicit or DAE systems, the situation is not so obvious. We discuss this question, in particular how to define the defect in a way such that optimal performance of the error estimation procedure may be expected. Further insight is gained by considering a set of test examples, in particular index 1 and 2 DAEs.
