Solutions of the neutral differential-difference equation αx′(t)+βx′(t−r)+γx(t)+δx(t−r)=f(t)

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1992
Particular solutions and complementary functions are obtained for the functional equation αx′(t)+βx′(t−r)+γx(t)+δx(t−r)=f(t) in the forms of a convolution type integral and of infinite series.

Oscillatory behaviour of a class of second order Emden-Fowler differential equations with a sublinear neutral term

open access: yesApplied Mathematics in Science and Engineering, 2023
This article is dedicated to the oscillatory properties of a second order Emden-Fowler delay differential equation with a sublinear neutral term. The presented criteria extend and improve several well-known results reported recently in the literature ...

Singularity Expansion for a Class of Neutral Equations

open access: yesJournal of Integral Equations and Applications, 2007
The authors study the structure of the solutions for a class of singular neutral equations arising from aerofoil model problem. The analysis is based on converting the neutral equation problem to Volterra integral equation of the second kind. It is shown that the solutions of the neutral equation can be decomposed into two parts, with one part being a ...

Impulsive partial neutral differential equations

open access: yesApplied Mathematics Letters, 2006
The authors establish conditions for the existence of mild and strong solutions of a partial neutral functional-differential equation with unbounded delay of the form \[ (d/dt)(x(t)+F(t, x_t)) = Ax(t)+G(t, x_t) \] subject to pre-assigned moments of impulse effects.

On a Quasi‐Neutral Approximation to the Incompressible Euler Equations [PDF]

open access: yesJournal of Applied Mathematics, 2012
We rigorously justify a singular Euler‐Poisson approximation of the incompressible Euler equations in the quasi‐neutral regime for plasma physics. Using the modulated energy estimates, the rate convergence of Euler‐Poisson systems to the incompressible Euler equations is obtained.

Exponential stability of solutions to nonlinear time-delay systems of neutral type

open access: yesElectronic Journal of Differential Equations, 2016
We consider a nonlinear time-delay system of neutral equations with constant coefficients in the linear terms $$ \frac{d}{dt}\big(y(t) + D y(t-\tau)\big) = A y(t) + B y(t-\tau) + F(t, y(t), y(t-\tau)), $$ where $$ \|F(t,u,v)\| \le q_1\|u\|^{1 ...

Asymptotic stability of a neutral integro-differential equation [PDF]

open access: yesOpuscula Mathematica, 2006
The global stability behavior of a non-autonomous neutral functional integro-differential equation is studied. A sufficient condition for every solution of this equation to tend to zero is given.

The semicycles of solutions of neutral difference equations

open access: yesApplied Mathematics Letters, 2000
The authors study the semicycles of solutions to the neutral delay difference equation \[ \Delta(y_n+ p_ny_{n-\tau}) +q_ny_{n-\sigma} =0. \] Here \(\{p_n\}\) and \(\{q_n\}\) are sequences of nonnegative real numbers, \(\tau\) and \(\sigma\) are positive integers. Upper bounds on the number of terms of semicycles are determined.
