Özet
In this manuscript, new oscillation criteria are given for solutions of h-order delay difference equation in the equation (1.1). There, four cases of (Formula presented.) are considered: for (Formula presented.), as oscillatory periodic sequences with periods (Formula presented.) and (Formula presented.) and a quickly oscillating sequence such that (Formula presented.). It is well-known that coefficient functions have a very important role in the behavior of the solutions of an equation. The coefficient sequence (Formula presented.) has been considered as positive sequences in all oscillation criteria so far. But it is considered as oscillatory periodic sequences and quickly oscillatory sequences for the first time in this study. We use a new technique to prove our results. Also, some examples are provided to demonstrate the effectiveness of the main results.
