ABSTRACT.
In this paper, some new oscillation criteria for second-order Emden-Fowler delay difference equations with a sublinear neutral term are presented. An important feature of the results is that oscillation of the equation under investigation is ensured via only one condition. The results essentially improve, extend and simplify some known ones reported in the literature. Examples are given to illustrate the results.
