Abstract

We develop results on (a) almost periodicity properties and (b) (exponential) asymptotic stability of solutions to the functional differential equations with infinite delay (FDE) $ \dot{x}(t) + \alpha x(t) + Bx(t) \ni F(x_t) , $ $ t \geq 0,$ $x |_{\mathbb{R}^-} = \varphi \in E $ in a context which allows for a (generally) nonlinear and multivalued accretive state-responsive operator $ B \subset X \times X $ in a Banach state space $ X $ and a locally defined and locally Lipschitz continuous history-responsive function $ F : D(F) \subset E \to X, $ in an appropriate initial history space $ E $ of continuous functions from $ \mathbb{R}^- $ into $ X. $ Applications to models from population dynamics (delay logistic equation) and biology (Goodwin oscillator) are presented.
