    Description / Table of Contents: Zusammenfassung Dieser Aufsatz befaßt sich mit der Analyse der Konvergenz von impliziten Runge-Kutta Verfahren für steife, semi-lineare Systeme der Form $$\dot U$$ (t)=QU(t)+g(t, U(t)). Ein Kriterium wird entwickelt, welches entscheidet, ob die Ordnung der optimalenB-Konvergenz mindestens gleich der Stufenordnung oder um eine Ordnung höher ist. Dieses Kriterium wird untersucht für eine Zahl von interessanten Klassen von Verfahren.
    Notes: Abstract This paper deals with the convergence analysis of implicit Runge-Kutta methods as applied to stiff, semilinear systems of the form $$\dot U$$ (t)=QU(t)+g(t, U(t)). A criterion is developed which determines whether the order of optimalB-convergence is at least equal to the stage order or one order higher. This criterion is studied for a number of interesting classes of methods.

    Notes: Abstract In a previous paper it was shown that for a class of semi-linear problems many high order Runge-Kutta methods have order of optimalB-convergence one higher than the stage order. In this paper we show that for the more general class of nonlinear dissipative problems such as result holds only for a small class of Runge-Kutta methods and that such methods have at most classical order 3.
