Halanay–Smith criterion. Let $M\in\mathcal G$. The following statements are equivalent:

Consider the linear retarded functional differential equation … where $a,b\in\mathbb{R}$ and $\eta$ is a probability distribution of delays. Fix the mean of $\eta$. Fixed-mean disc…

Consider the linear retarded functional differential equation … where $a,b\in\mathbb{R}$ and $\eta$ is a cumulative probability distribution function, possibly continuous, discrete…
