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

Singularity Expansion for a Class of Neutral Equations
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
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]
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
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]
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
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.
