On some properties of polynomial functions
In the paper sufficient conditions for the difference equation :Δxn = Σi=0r an(i) xn+ito have a solution which tends to a constant, are given. Applying these conditions, an asymptotic formula for a solution of an m-th order equation is presented.
For the linear difference equation sufficient conditions for the existence of an asymptotically periodic solutions are given.
Autonomous linear neutral delay and, especially, (non-neutral) delay difference equations with continuous variable are considered, and some new results on the behavior of the solutions are established. The results are obtained by the use of appropriate positive roots of the corresponding characteristic equation.
In this paper we investigate the global convergence result, boundedness and periodicity of solutions of the recursive sequence where the parameters and for are positive real numbers and the initial conditions are arbitrary positive numbers.
