Global stability in a differential equation with piecewisely constant arguments. (English) Zbl 0993.34052
The author considers a differential equation with piecewise constant arguments of the form $N'(t) = r(t)(-\mu N(t) + \sum_{i=0}^{m} P_i\exp{-r_i N([t-i])}), t\geq 0.$ Asymptotic properties of the coefficient $$r(t)$$ are used to define sufficient conditions for the global stability of a positive equilibrium.
