UniSa - IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishWe analyze the linear stability properties of mixed collocation Runge–Kutta–Nyström (RKN) methods for the second order Ordinary Differential Equations y"=f(x,y). In particular we consider the influence of the collocation nodes on the stability region, analyzing in detail the case of frequency and step length dependent RKN methods obtained through mixed collocation which are based on Gauss, Radau and Lobatto nodes. Keywords: Numerical methods for ODEs; Collocation methods; Runge–Kutta–Nyström methods; Stability analysis
