This paper is dealing with the oscillatory properties of first-order neutral delay impulsive differential equations and the corresponding inequalities with constant coefficients. The established sufficient conditions ensure the oscillation of every s

In this article, we consider first-order neutral impulsive differential equations with constant coefficients and constant delays. We study the asymptotic behavior of eventually positive solutions of these equations and establish necessary and suffici

In this paper we consider first order impulsive neutral differential equation with constant delay, constant coefficient into the neutral term and variable coefficient into the rest. The asymptotic behavior of a non-oscillatory solution for such equat
