Abstract

In this paper relationships between various one-step methods for the initial value problem in ordinary differential equations are discussed and a unified treatment of the stability properties of the methods is given. The analysis provides some new results on stability as well as alternative derivations for some known results. The term stability is used in the sense of A-Stability as introduced by Dahlquist. Conditions for any polynomial collocations method or its equivalent to be A-Stable are derived. These conditions may be easily checked in any particular case.
