Abstract

In this paper, we create a new explicit linear four-step singularly P-stable method with phase-lag of order infinity (phase-fitted) for the numerical solution of second-order initial value problems. The advantage of the new method in comparison with similar methods in terms of efficiency, accuracy, and stability is shown by its implementation in some well-known problems.
