THE DYNAMICS OF RUNGE–KUTTA METHODS

International Journal of Bifurcation and Chaos, 1992
The first step in investigating the dynamics of a continuous-time system described by an ordinary differential equation is to integrate to obtain trajectories. In this paper, we attempt to elucidate the dynamics of the most commonly used family of numerical integration schemes, Runge–Kutta methods, by the application of the techniques of dynamical ...

On the Stability of Volterra–Runge–Kutta Methods

SIAM Journal on Numerical Analysis, 1984
This paper examines the stability properties of extended Runge-Kutta methods when applied to Volterra integral equations of the second kind of the form \[ y(x)=f(x)+\lambda \int^{x}_{0}k(x-s)y(s)ds\quad(x\geq 0) \] where \(Re(\lambda)0\), \(k_ 0(x)=\overline{k_ 0(-x)}\), \(x\leq 0\) there is no such order barrier.

Interpolation for Runge–Kutta Methods

SIAM Journal on Numerical Analysis, 1985
The author discusses a new method for interpolation between mesh points of Runge-Kutta algorithms for the approximate solution of ordinary differential equations. The method is shown to fall under the classification of scaled Runge-Kutta algorithms as considered by \textit{M. K. Horn} [ibid. 20, 558-568 (1983; Zbl 0511.65048)].

Runge–Kutta Method

2019
The class of differential equations for which explicit solutions can be obtained is rather small. In fact, in Chap. 3, we have already remarked that to find an explicit solution of the second-order linear differential equation ( 3.2) there does not exist any method.

Positivity of Runge-Kutta and diagonally split Runge-Kutta methods

Applied Numerical Mathematics, 1998
The author investigates positivity of general Runge-Kutta and diagonally split Runge-Kutta methods for the numerical solution of positive initial value problems for ordinary differential equations. Conditions for the maximal stepsize in term of the radius of positivity of the Runge-Kutta method which guarantees positivity are given.

A Note on a Runge‐Kutta‐Chebyshev Method

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1982
Le but de ce travail est de présenter quelques considérations sur la solution numérique d'un problème avec valeur initiale pour des systèmes d'équations différentielles ordinaires de la forme \(y'=f(y)\), qui jouïssent de la propriété que les valeurs propres de la matrice jacobienne \(J(f)=\partial f(y)/\partial y\) sont situées sur une bande longue et

Runge–Kutta–Chebyshev projection method

Journal of Computational Physics, 2006
In this paper a fully explicit, stabilized projection method called the Runge-Kutta-Chebyshev (RKC) projection method is presented for the solution of incompressible Navier-Stokes systems. This method preserves the extended stability property of the RKC method for solving ODEs, and it requires only one projection per step.
