Almost Periodic Solutions of Lasota]Wazewska-type Delay Differential Equation

Sufficient conditions are derived for the existence of a globally attractive almost periodic solution of a single species model given by the nonautonomous Lasota]Wazewska-type delay differential equations, xX t.syd t.x t. qp t.f x tyt .., in which t )0, p t.G0, d t. are continuous almost periodic functions, and f is a decreasing positive C1-function. Conditions of the uniform asymptotical stability for some associated nonautonomous delay differential equations, xX t.syd t.x t. qp t.x tyt ., are also discussed.
