On global attractivity of nonlinear delay difference equations with a forcing term.

In this paper, we study global attractivity of solutions of the delay difference equation with a forcing term where {p(n)} is a nonnegative sequence, f:R?R is a continuous function with xf(x)>0 for x?0, {r(n)} is a real sequence, and k is a nonnegative integer. Several global attractivity results are obtained. [ABSTRACT FROM AUTHOR]
