โฆ Synopsis
For a class of nonlinear homogeneous difference equations with periodic coefficients, it is shown that every nonoscillatory entire solution has exponential bounds and that the oscillation is equivalent to nonexistence of a part of positive characteristic roots. Sufficient conditions for oscillation in terms of coefficients are also obtained.

A nonlinear difference equation with periodic coefficients and constant delays is considered in this note and an oscillation criterion is obtained. This criterion is obtained by means of a generalized characteristic equation. Published by Elsevier Science Ltd.
In this paper, we investigate the oscillation and nonoscillation of the neutral difference equation with variable coefficients where pn,qn, c~n (n = 0,1,2,...) are real numbers with pn >\_ 0, qn >\_ 0, cn \_> 0, k, l, and r are integers with 0 < I < k -1, r > 0, Pn -qn-k+l ~--0, and not identically
In this work, the oscillatory and asymptotic properties of higher order nonlinear neutral difference equations with oscillating coefficients are studied. Some new necessary and sufficient criteria, which improve several known results, are obtained.
