A sufficient condition of stability of exponential Runge-Kutta methods for delay differential equations is obtained. Furthermore, a relationship between P-stability and GP-stability is established. It is proved that the numerical methods can preserve the analytical stability for a class of test prob

✦ Synopsis
We investigate stability properties of two-step Runge-Kutta methods with respect to the linear test equation y'(t) = ay(t) + by(t -T), t > O,
where a and b are complex parameters. It is known that the solution y(t) to this equation tends to zero as t --~ oc if Ibl < -Re(a). We will show that under some conditions this property is inherited by any A-stable two-step Runge-Kutta method applied on a constrained mesh to delay differential equations, i.e., that the corresponding method is P-stable.

By using the Kreiss resolvent condition we establish upper bounds for the growth of errors in Runge-Kutta schemes for the numerical solution of delay differential equations. We consider application of such a scheme to the well-known linear test equation Z (t) = λZ(t) + µZ(tτ ), and prove that at any
