| Abstract: | This article discusses all-delays stability of degenerate delay system with distributional delay. Firstly we give the sufficient condition of the character equation of degenerate delay system problem, when the singular system is stable. Secondly we give out the character equation of degenerate delay system problem with distributional delay. Then we can get the sufficient and necessary condition of the all-delays stability of the system. At last, we generalize the main result to the system that has several delays. |
