Necessary and Sufficient Condition for Oscillation of Higher Order Nonlinear Delay Difference Equations
-This paper is concerned with the oscillation of solutions of higher order nonlinear delay difference equations with forcing terms of the form Anx(t) + f(t, x(t),x(a(t))) = h(t), t E I = {0, 1 . . . . }, where A is the forward difference operator defined by Ax(t) = x(t + 1) -x(t) and A'nx(t) = A(Am-lx(t)), m > 1. A necessary and sufficient condition is established under which every solution x(t...

where {pi(n)} are sequences of nonnegative real numbers and not identically equal to zero, and ki is positive integer, i = 1,2, . . . , and is the first-order forward difference operator, xn = xn+1− xn, and xn = l−1( xn) for l ≥ 2. By a solution of (1.1) or inequality (1.2), we mean a nontrival real sequence {xn} satisfying (1.1) or inequality (1.2) for n ≥ 0. A solution {xn} is said to be osci...
متن کاملNecessary and sufficient conditions for oscillation of first order neutral delay difference equations
In this paper, we obtained some necessary and sufficient conditions for oscillation of all the solutions of the first order neutral delay difference equation with constant coefficients of the form ∆[x(n)− px(n− τ)] + qx(n− σ) = 0, n ≥ n0 (∗) by constructing several suitable auxiliary functions. Some examples are also given to illustrate our results.

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 کاملOscillation 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
