The Convergence of Variable-Stepsize, Variable-Formula, Multistep Methods

In this paper variable-stepsize, variable-formula, multistep methods for the numerical solution of ordinary differential equations are considered. Some more general results on stability than are given in the papers of Gear–Tu [SIAM J. Numer. Anal., 11 (1974), pp. 1025–1043] and Gear–Watanabe [SIAM J. Numer. Anal., 11 (1974), pp. 1044–1058] are obtained. Further, the asymptotic behavior of the error in the variable-stepsize, fixed-formula case is studied. Finally, the above study is extended to predictor-corrector methods.
