On the perturbations of regular linear systems and linear systems with state and output delays. (English) Zbl 1237.47011

The authors of the paper under review study the problem of regularity of linear systems under perturbations. They consider two types of perturbations of linear systems. The results are applied to linear systems with state and output delays.
