Existence of Nonoscillatory Solution of High Order Linear Neutral Delay Difference Equation

Shasha Zhang, Xiaozhu Zhong, Ping Yu, Wenxia Zhang, Ning Li


Consider the high order neutral delay difference equation with positive and negative coefficients

Where are positive real sequences. A sufficient condition for the existence of the eventually positive solution of the above equation is set forward in terms of . This result got rid of a quite strong tentative of existing literature, which improve the relevant theorem.
