Neutral Operator and Neutral Differential Equation [PDF]

open access: yesAbstract and Applied Analysis, 2011
In this paper, we discuss the properties of the neutral operator (Ax)(t)=x(t)−cx(t−δ(t)), and by applying coincidence degree theory and fixed point index theory, we obtain sufficient conditions for the existence, multiplicity, and nonexistence of ...

Neutral set differential equations [PDF]

open access: yesCzechoslovak Mathematical Journal, 2015
The aim of this paper is to establish an existence and uniqueness result for a class of the set functional differential equations of neutral type {DHX(t)= F(t,Xt,DHXt), where F: [0, b] x Co x 4-) K(E) is a given function, K(E) is the family of all nonempty compact and convex subsets of a separable Banach space E, Co denotes the space of all continuous ...

Third order non-linear difference equation with neutral term [PDF]

open access: yesE3S Web of Conferences, 2023
This paper aims to investigate the oscillatory characteristics of a neutral third order nonlinear difference equation. Utilizing the comparison principle, we get some new standards that guarantee that any solution to the neutral difference equation ...

Oscilations of higher-order neutral equations [PDF]

open access: yesThe Journal of the Australian Mathematical Society. Series B. Applied Mathematics, 1986
AbstractSufficient conditions are given for the occurrence of various types of asymptotic behaviour in the solution of a class of n th order neutral delay differential equations. The conditions are in the form of certain inequalities amongst the constants involved in the definition of the differential equations, and specify either oscillatory behavior,

Oscillatory Properties of the Solutions of First Order Linear Neutral Differential Equations with "Maxima"

open access: yesCommunications, 2013
In this paper we consider a neutral differential equation with "maxima" of the form [x(t) + p(t)x(σ(t))] + q(t) max x(s) = 0 We obtained sufficient conditions for oscillation of all the solutions when t→∞.

Oscillations for Neutral Functional Differential Equations [PDF]

open access: yesThe Scientific World Journal, 2014
We will consider a class of neutral functional differential equations. Some infinite integral conditions for the oscillation of all solutions are derived. Our results extend and improve some of the previous results in the literature.

Periodic Solution for a Kind of Third-Order Neutral-Type Differential Equation

open access: yesJournal of Function Spaces, 2023
In this paper, we investigate a class of a third-order neutral-type differential equation with time-varying delays. Some sufficient conditions on the existence of a periodic solution are established for the considered system.

Neutral Equations and Associated Semigroups

open access: yesJournal of Differential Equations, 1995
Semigroup representations of hereditary functional equations are studied. In particular, the results deal with the neutral functional equation \({d\over dt} D_ t x= Lx_ t+ f(t)\), where \(L\in \beta(C([-1, 0], \mathbb{R}^ n))\) and \(D\) denotes Hale's operator.

Oscillation criteria for neutral half-linear differential equations without commutativity in deviating arguments

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2016
We study the half-linear neutral differential equation \begin{equation*} \Bigl[r(t)\Phi(z'(t))\Bigr]'+c(t)\Phi(x(\sigma(t)))=0, \qquad z(t)=x(t)+b(t)x(\tau(t)), \end{equation*} where $\Phi(t)=|t|^{p-2}t$.
