Phase-fitted partitioned Runge-Kutta methods for separable oscillatory Hamiltonian systems and related problems

We present an approach for deriving some phase-fitted Parti tioned Runge-Kutta (PRK) methods for numerical integration of separable Hamiltonian and related systems. The approach constitute the modification of the existing PRK such that some parameters are modified to eliminate the phase-lag and the amplification error using the analysis of phase pr...
