چکیده
The propose of the paper is devoted to study existence ?-periodic solutions for second order delay differential equation in abstract Banach space. Firstly, we build a new maximum principle corresponding linear equation. Secondly, with help this principle, minimal and maximal periodic our concerns problem by means perturbation method monotone iterative technique lower upper solutions. In addition, an example presented show application main results.

متن کاملExistence of Positive Periodic Solutions for a Third-order Delay Differential Equation
In this paper, the following third-order nonlinear delay differential equation with periodic coefficients x′′′(t) + p(t)x′′(t) + q(t)x′(t) + r(t)x(t) = f (t, x (t) , x(t− τ(t))) + c(t)x′(t− τ(t)), is considered. By employing Green’s function and Krasnoselskii’s fixed point theorem, we state and prove the existence of positive periodic solutions to the third-order delay differential equation.
