✦ Synopsis


In

this paper, we use the upper and lower solutions method to show that there exists a A*, such that the nonlinear functional difference equation of the form

has at least one positive T-periodic solutions for A E (0, A*] and does not have any positive T-periodic solutions for A > A*, where a(n), h(n), and ~-(n) are T-periodic functions. @

We extend to difference equations the classical method of harmonic balance. We show that the method can be used to obtain an approximation to the periodic solutions of a special class of second-order nonlinear di$erence equations containing a small parameter. Two examples illustrating the method are
