Ag. Xiao et al., Regularity properties of general linear methods for initial value problemsof ordinary differential equations, APPL NUM M, 34(4), 2000, pp. 405-420
The main purpose of the present paper is to examine the asymptotic states o
f general linear methods for initial value problems of ordinary differentia
l equations, and to extend the existing relevant results of Runge-Kutta met
hods, linear multistep methods by Humphries (1993) and Stuart and Humphries
(1993). In particular, the existence of spurious steady solutions and peri
od-2 solutions in the time step is studied, and the concepts of (strong and
weak) R-[1]-regularity and (weak) R-[2]-regularity of general linear metho
ds are introduced and studied. Some sufficient conditions for (strong and w
eak) R-[1]-regularity and (weak) R-[2]-regularity of such methods applied t
o initial value problems of ordinary differential equations with a globally
Lipschitz condition or contractive or monotone condition are given. (C) 20
