Stability as well as optimal error estimates are derived for step size ratios bounded by 1.91.en510 Mathematiksemilinear parabolic problemtime discretisationbackward differentiation formulanon-uniform gridstabilityerror estimateStability and error of the variable two-step BDF for parabolic problemsResearch Paper
