P-Stable Higher Derivative Methods with Minimal Phase-Lag for Solving Second Order Differential Equations
Some new higher algebraic order symmetric various-step methods are introduced. For these methods a direct formula for the computation of the phase-lag is given. Basing on this formula, calculation of free parameters is performed to minimize the phase-lag. An explicit symmetric multistep method is pr...
