Abstract
This paper is concerned with the study of the delaydependent stability of Runge–Kutta methods for delay differential equations First a new sufficient and necessary condition is given for the asymptotic stability of analytical solution Then based on this condition we establish a relationship between τ0stability and the boundary locus of the stability region of numerical methods for ordinary differential equations Consequently a class of high order Runge–Kutta methods are proved to be τ0stable In particular the τ0stability of the Radau IIA methods is proved
