摘要
In this paper, necessary and sufficient conditions for the existence and classification of positive solutions of the higher-order neutral difference equation [GRAPHICS] are obtained, where r(n) > 0, p(n)(i) greater than or equal to 0, i = 1, 2,..., m, and f(n, s(1),.... s(1)) is continuous with respect to n and s(j), j = 1,..., l.
