โœฆ Synopsis

Linear delay or advanced difference equations with variable coefficients and not (neceasarlly) constant delays or advanced arguments are considered, and some new oscillation and nonoscll-l&ion criteria are given. More precisely, sufficient conditions for the oscillation of all solutions are obtained; moreover, conditions which guarantee the existence of positive solutions are derived.

## In this paper, we obtain some sharp conditions for oscillation and nonoscillation of the difference equation with variable delays where m is a positive integer, {ki(n)}r=,, and {pi(n)}~& (i = 1,2,. , m) are sequences of positive integers and real numbers, respectively. Our results improve and e

In this study, a new companion transformation is used for the neutral delay difference equation where n โˆˆ Z, R, P, Q are nonnegative sequences and r, k, l are positive integers. New criteria, which do not need the conditions and/or for all sufficiently large n, are introduced. All the recent resu
