Abstract
This paper contains new estimates for the distance between adjacent zeros of solutions of the first order delay differential equation x′(t)+p(t)x(t−τ)=0x′(t)+p(t)x(t−τ)=0 where pp is a nonnegative continuous function. Our results are new and improve some known criteria. Illustrative examples are given to show the strength of some obtained results over the known ones.
