Abstract.  Many phenomena in mathematical physics and in the theory ofdynamical populations are described by difference equations. The aim of this work is to present new approach to study the qualitative properties of solutions for some algebraic difference equations. The technique used is based on convergence of series associated with the forcing term. We also consider the problem of existence of almost periodic solution by the compactly characterization of family associated with the forcing term. For illustration, we provide some applications. Our results generalizes the main results of our precedent work in [E.Ait Dads & L. Lhachimi, 2016].
