Periodic solutions of convex neutral functional differential equations [PDF]

open access: yesTohoku Mathematical Journal, 2000
In this paper, the authors study the existence of periodic solutions to neutral differential equations. It is proved that for convex neutral functional-differential equations of \(D\)-operator type with finite (or infinite) delay and hyperneutral functional-differential equations with finite delay the problem of the existence of periodic solutions is ...

Oscillation of solutions for odd-order neutral functional differential equations [PDF]

open access: yesElectronic Journal of Differential Equations, 2010
In this article, we establish oscillation criteria for all solutions to the neutral differential equations $$ [x(t)pm ax(tpm h)pm bx(tpm g)]^{(n)} =pint_c^d x(t-xi)dxi+qint_c^d x(t+xi)dxi, $$ where $n$ is odd, $h$, $g$, $a$ and $b$ are nonnegative

Some New Existence Results for Positive Periodic Solutions to First-Order Neutral Differential Equations with Variable Coefficients [PDF]

open access: yes, 2022
In this article, we deal with some new existence results for positive periodic solutions for a class of neutral functional differential equations by employing Krasnoselskii’s fixed-point theorem and the properties of a neutral operator. Our results

Collocation schemes for periodic solutions of neutral delay differential equations [PDF]

open access: yes, 2005
We introduce two collocation schemes for the computation of periodic solutions of neutral delay differential equations (NDDEs): one based on a direct discretisation of the underlying NDDE, and one based on a discretisation of a related delay differential
