چکیده
We obtain sufficient conditions for oscillation of all solutions of the neutral impulsive difference equation with continuous variable Δτ(y(t) +P(t)y(t−mτ)) +Q(t)y(t− lτ)= 0, t ≥ t0− τ, t = tk, y(tk + τ)− y(tk)= bk y(tk), k ∈N(1), where Δτ denotes the forward difference operator, that is, Δτz(t)= z(t+ τ)− z(t), P(t)∈ C([t0− τ,∞),R ),Q(t)∈ C([t0− τ,∞),(0,∞)),m, l are positive integers, τ > 0 and bk are constants, 0≤ t0 < t1 < t2 < ··· < tk < ··· with limk→∞ tk =∞.

Forced Oscillation of Neutral Impulsive Parabolic Partial Differential Equations with Continuous Distributed Deviating Arguments
This paper investigated oscillatory properties of solutions for nonlinear parabolic equations with impulsive effects under two different boundary conditions. By using integral averaging method, variable substitution and functional differential inequalities, we established several sufficient conditions. At last, we provided two examples to illustrate the results.
متن کاملOscillation criteria for a class of neutral difference equations with continuous variable
In this paper, we are mainly concerned with oscillatory behaviour of solutions for a class of second order nonlinear neutral difference equations with continuous variable. Using an integral transformation, the Riccati transformation and iteration, some oscillation criteria are obtained. 2003 Elsevier Inc. All rights reserved.

Impulsive integrodifferential Equations and Measure of noncompactness
This paper is concerned with the existence of mild solutions for impulsive integro-differential equations with nonlocal conditions. We apply the technique measure of noncompactness in the space of piecewise continuous functions and by using Darbo-Sadovskii's fixed point theorem, we prove reasults about impulsive integro-differential equations for convex-power condensing operators.
