Abstract

Asymptotic properties of solutions of a difference equation of the form are studied. We present sufficient conditions under which, for any polynomial of degree at most and for any real , there exists a solution x of the above equation such that . We give also sufficient conditions under which, for given real , all solutions x of the equation satisfy the condition for some polynomial of degree at most . MSC:39A10.

Summary

Introduction

Let N, Z, R denote the set of positive integers, the set of all integers and the set of real numbers, respectively. In [ ], Popenda and Drozdowicz presented necessary and sufficient conditions under which the equation mxn = anf (xn) has a convergent solution (i.e., a solution that is asymptotically polynomial of degree zero). In [ ] sufficient conditions under which, for any φ ∈ Pol(m – ), there exists a solution x of the equation mxn = anf (xn) + bn such that xn = φ(n) + o( ) are presented. In [ ] sufficient conditions under which every solution x of the equation mxn = anF(n, xg(n)) + bn has the property xn = φ(n) + o( ) for some φ ∈ Pol(m – ) are presented. Sufficient conditions under which, for every φ ∈ Pol(m – ) there exists a solution x of this equation such that xn = φ(n) + o( ), are presented.
