Oscillation of solutions for odd-order neutral functional differential equations

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

Oscillation results for even-order quasilinear neutral functional differential equations

open access: yesElectronic Journal of Differential Equations, 2011
In this article, we use the Riccati transformation technique and some inequalities, to establish oscillation theorems for all solutions to even-order quasilinear neutral differential equation $$ Big(ig[ig(x(t)+p(t)x(au(t))ig)^{(n-1)}ig]^gammaBig)' +

Weighted pseudo periodic solutions of neutral functional differential equations

open access: yesElectronic Journal of Differential Equations, 2014
In this article, we introduced and explore the properties of two sets of functions: weighted pseudo periodic functions of class r, and weighted Stepanov-like pseudo periodic functions of class r. We show the existence and uniqueness of weighted pseudo

Periodic solutions for some partial neutral functional differential equations

open access: yesElectronic Journal of Differential Equations, 2006
In this work, we study the existence of periodic solutions for partial neutral functional differential equation. We assume that the linear part is not necessarily densely defined and satisfies the Hille-Yosida condition.

Oscillation of Second-Order Neutral Functional Differential Equations with Mixed Nonlinearities

open access: yesAbstract and Applied Analysis, 2011
We study the following second-order neutral functional differential equation with mixed nonlinearities (r(t)|(u(t)+p(t)u(t-σ))'|α-1(u(t)+p(t)u(t-σ))′)′+q0(t)|u(τ0(t))|α-1u(τ0(t))+q1(t)|u(τ1(t))|β-1u(τ1(t))+q2(t)|u(τ2(t))|γ-1u(τ2(t))=0, where γ>α>β>0, ∫t0∞

Neutral functional differential equations of second-order with infinite delays

open access: yesElectronic Journal of Differential Equations, 2010
This work shows the existence of mild solutions to neutral functional differential equations of second-order with infinite delay. The Hausdorff measure of noncompactness and fixed point theorem are used, without assuming compactness on the associated

Asymptotic Behavior of Higher-Order Quasilinear Neutral Differential Equations

open access: yesAbstract and Applied Analysis, 2014
We study asymptotic behavior of solutions to a class of higher-order quasilinear neutral differential equations under the assumptions that allow applications to even- and odd-order differential equations with delayed and advanced arguments, as well as to

Spectral Properties and Finite Pole Assignment of Linear Neutral Systems in Banach Spaces

open access: yesAbstract and Applied Analysis, 2010
We will consider a pole assignment problem for a class of linear neutral functional differential equations in Banach spaces. We will think of the neutral system studied as that of involving no time delays and reduce the study of adjoint semigroups and ...
