| Abstract: | This paper is concerned with the oscillatory behavior of a class of higher order nonlinear neutral delay functional difference equation with positive and negative coefficients. By using the fixed point theorem in Banach space, and a lot of inequality techniques, some new nonoscillation criteria for the equation were obtained. |
