Abstract |
|
In this work we consider symplectic Runge Kutta Nystršom (SRKN) methods with three stages. We construct a fourth order
SRKN with constant coefficients and a trigonometrically fitted SRKN method. We apply the new methods on the two-dimentional
harmonic oscillator, the Stiefel-Bettis problem and on the computation of the eigenvalues of the Schršodinger equation. |
