Abstract
We obtain new sufficient conditions for the oscillation of all solutio ns of the first-order linear delay differential equation x'(t) + p(t)x (tau(t)) = 0, with p(t) greater than or equal to 0,tau(t)< t. Our resu lts improve the known results in the literature which include those ob tained recently in papers by Elbert and Stavroulakis, Li, and Yu ct al . (C) 1998 Elsevier Science Ltd..
