This article studies the positivity and stability of homogeneous coupled differential-difference
equations with time-varying delays. First, a sufficient positivity condition is proposed for the …

This work focuses on linear continuous‐time systems with time‐varying delays, in the
general case of time‐varying matrices. Initially, we explore the case of positive systems …

The stability analysis of time-delay systems is a tough task even in the linear case,
especially when time-varying delays are considered. In recent years, for the class of positive …

This work introduces novel results on the stability of linear time-varying discrete-time delay
systems, addressing both internal stability and input-to-state stability. We start from the …

Stability theory of linear differential–difference system has been well-established, while
fewer results can be found for nonlinear differential–difference systems. In this article …

Switched models whose dynamic matrices are in block companion form arise in theoretical
and applicative problems such as representing switched ARX models in state‐space form …

This article introduces novel results on linear coupled differential-difference systems with
multiple time-varying delays. First, necessary and sufficient conditions for the positivity and …

Inspired by some insightful results on the delay-independent stability of discrete-time
systems with time-varying delays, in this work we study the arbitrary switching stability for …

This work provides 1-moment stability conditions for discrete-time Markov Jump Linear
Systems under time-homogeneous and time-inhomogeneous transition probabilities. For the …

This work introduces the internally positive representation of linear time‐varying delay
differential systems, in the general case of multiple time‐varying delays. The technique …
