Oscillation of second order nonlinear neutral delay difference equations
In this paper sufficient conditions are obtained for oscillation of all solutions of a class of nonlinear neutral delay difference equations of the form ∆(y(n) + p(n)y(n−m)) + q(n)G(y(n − k)) = 0 under various ranges of p(n). The nonlinear function G,G ∈ C(R,R) is either sublinear or superlinear. Mathematics Subject classification (2000): 39 A 10, 39 A 12
متن کاملOscillation theorems for second-order nonlinear delay difference equations
By means of Riccati transformation technique, we establish some new oscillation criteria for second-order nonlinear delay difference equation ∆(pn (∆xn) ) + qnf(xn−σ) = 0, n = 0, 1, 2, . . . ,
متن کاملOn Oscillation of Second-Order Nonlinear Neutral Functional Differential Equations
In this paper, some sufficient conditions are established for the oscillation of second-order neutral functional differential equation [ r(t)[x(t)+ p(t)x(τ(t))]′ ]′+q(t) f (x(σ(t))) = 0, t ≥ t0, where ∫ ∞ t0 dt/r(t) = ∞, or ∫ ∞ t0 dt/r(t) < ∞, 0 ≤ p(t) ≤ p0 < ∞. The results obtained here complement and improve some known results in the literature. 2010 Mathematics Subject Classification: 39A21,...
متن کاملOscillation of Second Order Nonlinear Dynamic Equations on Time Scales
By means of Riccati transformation techniques, we establish some oscillation criteria for a second order nonlinear dynamic equation on time scales in terms of the coefficients. We give examples of dynamic equations to which previously known oscillation criteria are not applicable.
متن کاملOscillation criteria for nonlinear second-order difference equations with a nonlinear damped term
Sufficient conditions for the oscillation of solutions of the nonlinear second-order difference equation of the form [p(k)ψ(y(k)) y(k)] + q(k)h(y(k))g( y(k − r(k))) y(k) + f (k, y(k), y(k − s1(k)), y(k − s2(k)), . . . , y(k − sn(k))) = 0 are established. We obtain a series of results for oscillatory behaviour. © 2004 Elsevier Ltd. All rights reserved. MSC: 39A10
