| Abstract: | The asymptotic stability of the zero solution of a delay-differential system was investigated by means of the matrix measure and the contraction mapping principle through a restriction function and several inequalities satisfied with the matrix measure of a linear system. The result of one-dimensional perturbed equation was generalized to the multi-dimensional system, some research results obtained in the field was supplemented. Finally, an example was given to illustrate the result and make a comparison with the result of Liapunov method. |
| Keywords: | fixed point delay-differential systems asymptotic stability matrix measure contraction mapping principle |
