| Abstract: |
| This paper deals with the stability analysis of the Rosenbrock methods for the numerical solutions of the systems of differential equations with many delays.The GPmL-stability behavior of the Rosenbrock methods is analyzed for the solutions of linear test equations.We show that the Rosenbrock methods are GPmL-stable if and only if they are L-stable. |
| Key words: delay differential equation GPmL-stability Rosenbrock method |
