Global stability for a class of delay differential equations. (English) Zbl 1064.34061
The paper is concerned with the study of the behavior of solutions of the delay differential equation ${\dot x}(t) = \alpha f(x(t-1)), x(t) = x^0(t) \quad\text{for }t \in [-1, 0]$ where $$\alpha \geq 0$$ and $$f$$ is a continuously differentiable unimodal mapping with $$f(0)=f(1)=0$$. The author gives sufficient conditions for the nonnegativity of solutions of the equation and for the global stability of the solutions.
