| Abstract: | This paper deals with the stability of the IRK method for the numerical solution of a delay differential e-quation with many delays. The GPLm-stability of the IRK method is analyzed for the solutions of linear test equations.It is shown that the IRK method is GPLm-stable ff and only ff it is L-stable. |
