摘要：
The oscillatory behavior of solutions of the neutral difference equations with nonlinear neutral term, Delta(x(n)-p(n)x(n)(alpha)-tau) + q(n)x(n-sigma)(beta) = 0, n >= n(0), is studied in the case when a not equal 1. A necessary and sufficient oscillatory conditions for the case 0 < alpha < 1 and an almost "sharp" oscillatory and nonoscillatory criteria for the case alpha > 1 are obtained. (c) 2006 Elsevier Ltd.
