This paper considers modified second derivative BDF (MSD-BDF) for the numerical solution of stiff initial value problems (IVPs) in ordinary differential equations (ODEs). The methods are A ( α ) -stable for step length k ≤ 7 .

A ( α )-Stable Linear Multistep Methods for Stiff IVPs in ODEs

R. I. Okuonghae, M. N. O. Ikhile (2011)

Acta Universitatis Palackianae Olomucensis. Facultas Rerum Naturalium. Mathematica

Similarity:

In this paper, a class of A( α )-stable linear multistep formulas for stiff initial value problems (IVPs) in ordinary differential equations (ODEs) is developed. The boundary locus of the methods shows that the schemes are A-stable for step number k ≤ 3 and stiffly stable for k = 4 , 5 and 6 . Some numerical results are reported to illustrate the method.
