On almost periodic solutions of logistic delay differential equations with almost periodic time dependence

摘要

In this paper, we study almost periodic logistic delay differential equations. The existence and module of almost periodic solutions are investigated. In particular, we extend some results of Seifert in [G. Seifert, Almost periodic solutions of certain differential equations with piecewise constant delays and almost periodic time dependence, J. Differential Equations 164 (2000) 451-458]. (c) 2006 Elsevier Inc. All rights reserved.
