摘要
This paper deals with the convergence analysis of implicit Runge-Kutta methods as applied to stiff, semilinear systems of the form du(t)/dt equals QU(t) plus g(t,U(t)). A criterion is developed which determines whether the order of optimal B-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.
