ASYMPTOTIC STABILITY FOR A HIGHER-ORDER RATIONAL <strong>DIFFERENCE</strong> EQUATION M. DEHGHAN, C. M. KENT, AND H. SEDAGHAT For the rational difference equation x n = (α + ∑ m i=1 a i x n−i )/(β + ∑ m i=1 b i x n−i ), n = 1,2,..., we obtain sufficient conditions for the asymptotic stability of a unique fixed point relative to an invariant interval. We focus on negative values for the coefficients a i ,arangethat has not been considered previously. Copyright © 2006 M. Dehghan et al.

Introduction Consider the higher-order difference equation x n = f ( x n−1 ,...,x n−m ) , n = 1,2,..., (1.1) where m is a nonnegative integer and f : R m → R is a given function. In the literature on difference equations, problems involving the asymptotic stability of fixed points of (1.1) in the case in which f is monotonic (nonincreasing or nondecreasing) in each of its arguments or coordinates arise frequently. In particular, the general rational difference equation x n = α + ∑ m i=1 a i x n−i β + ∑ m i=1 b i x n−i , n = 1,2,..., (1.2) and various special cases of it have been studied extensively in the literature; see, for example, [3, 5] for a discussion of (1.2) in its general form and [4] for a discussion of the second-order case. The bibliographies in these books contain numerous references to additional results that discuss asymptotic stability for various special cases. In this paper we consider (1.2) in its general form above and give conditions for the asymptotic stability of a fixed point relative to an invariant interval that contains the fixed point. Our results concern a range of parameters, including negative coefficients, that extend those previously considered elsewhere.
