| Abstract: |
| This paper deals with nonlinear stability analysis of both analytical solutions and numerical approximations to nonlinear systems of generalized delay differential equations with variable delay terms.First,a sufficient condition for the asymptotical stability of the theoretical solution is discussed.Then,we investigate the GAR(l)-numerical stability of Runge-Kutta methods for systems of generalized delay differential equations with a variable lag,numerical test confirms our theoretical results. |
