Abstract: In this paper, necessary and sufficient conditions for the existence of nonoscillatory solutions of the forced nonlinear difference equation $$ \Delta (x_{n}-p_{n} x_{\tau (n)})+f(n,x_{\sigma (n)})=q_{n} $$ are obtained. Examples are included to illustrate the results.

Keywords: difference equations, nonlinear, forced term, nonoscillation

Classification (MSC2000): 39A10
