Stability of IMEX (implicit-explicit) Runge-Kutta methods applied to delay differential equations (DDEs) is studied on the basis of the scalar test equation du/dt = u(t) + u(t -), where is a constant delay and , are complex parameters. More specifically, P-stability regions of the methods are define

β¦ Synopsis
This paper is concerned with the stability of multistep R.unge-Kutta methods applied to linear systems of functional-differential and functional equations. The adaptation of multistep Runge-Kutta methods is considered. It is proved that, under some reasonable assumptions, Astability multistep Runge-Kutta methods can inherit the asymptotic stability of underlying linear systems.

This paper deals with stability properties of Runge-Kutta methods for the initial value problem in nonlinear neutral delay differential equations The new concepts of GS(l)-stability, GAS(l)-stability and Weak GAS(l)-stability are introduced, and it is shown that (k, l)algebraically stable Runge-Kut
Runge-Kutta formulas are discussed for the integration of systems of differential equations. The parameters of these formulas are square matrices with component-dependent values. The systems considered are supposed to originate from hyperbolic partial differential equations, which are coupled in a s
