In this work we define Ψ -boundedness of sequences and discuss the existence of Ψ -bounded solutions for linear difference equations. We present a necessary and sufficient condition for the existence of Ψ -bounded solutions for the linear nonhomogeneous difference equation x(n + 1) = A(n)x(n)+ f (n). c © 2006 Elsevier Ltd.

Research Article Unbounded Perturbations of Nonlinear Second-Order Difference Equations at Resonance
In this paper, sufficient conditions are established for the oscillatory and asymptotic behavior of higher–order half–linear delay difference equation of the form ∆(pn(∆ (xn + qnxτn)) ) + rnx β σn = 0, n ≥ n0, where it is assumed that ∑∞ s=n0 1/p 1/α s < ∞. The main theorem improves some existing results in the literature. An example is provided to demonstrate the effectiveness of the main result.
