摘要

In this paper, we explore the strong stability preserving (SSP) conditions for implicit second derivative multistep methods (SDMMs) when forward Euler condition is coupled with different second derivative conditions. We construct optimal SSP implicit SDMMs up to order \(p=8\) p = 8 for \(k \le 10\) k 10 steps, which have larger SSP coefficients than the class of implicit linear multistep methods. Numerical experiments confirm that the proposed methods are capable in solving stiff problems preserving the positivity property without producing spurious oscillations.
