Abstract:
Oscillation criteria for all solutions of the first order delay difference equation of the formwhere {pn} is a sequence of nonnegative real numbers and k is a positive integer are established especially in the case that the well-known oscillation conditionsare not satisfied.Dedicated to Professor Y.G. Sficas on the occasion of his 60h birthday
