Abstract Well-known stability concepts for Runge-Kutta methods areA-stability andB-stability. These stability properties can be characterized by algebraic conditions related to the generating matrix of the method. In this note we show, thatI-stable methods can be characterized similarly, yielding aunified description ofB-,A- andI-stability in terms of a matrixR.I-stability, although a weaker concept thanA-stability, is of some relevance in parallelizing Runge-Kutta methods.
