Some oscillation results for even order delay difference equations with a sublinear neutral term.(English)Zbl 1470.39025

Summary: In this paper, some new results are obtained for the even order neutral delay difference equation $$\Delta \left(a_n \Delta^{m - 1} \left(x_n + p_n x_{n - k}^\alpha\right)\right) + q_n x_{n - \ell}^\beta = 0$$, where $$m \geq 2$$ is an even integer, which ensure that all solutions of the studied equation are oscillatory. Our results extend, include, and correct some of the existing results. Examples are provided to illustrate the importance of the main results.
