Positive periodic solutions for second-order neutral differential equations with functional delay

open access: yesElectronic Journal of Differential Equations, 2012
We use Krasnoselskii's fixed point theorem to prove the existence of positive periodic solutions of the second-order nonlinear neutral differential equation $$ frac{d^2}{dt^2}x(t)+p(t)frac{d}{dt}x(t)+q(t)x(t) =cfrac{d}{dt}x(t-au(t))+f(t,h(x(t)),g(x ...

Asymptotic behavior of solutions to a class of linear non-autonomous neutral delay differential equations

open access: yesElectronic Journal of Differential Equations, 2011
We study a class of linear non-autonomous neutral delay differential equations, and establish a criterion for the asymptotic behavior of their solutions, by using the corresponding characteristic equation.
