Abstract
In this note, we show the existence of a global positive solution for a class of first-order delay differential equations: x <sup>'</sup>(t)+a <inf>1</inf>(t)x(t)+a <inf>2</inf>(t)x(t-h(t))=0. In this study, we allow a <inf>1</inf> and a <inf>2</inf> to be of oscillating nature. © 2012 Elsevier Ltd. All rights reserved.
