Asymptotic behavior of solutions of certain difference equations
Consider the following two difference equations \[ \Delta y_n= \sum^m_{k=1} a_k(n) f_k(y_{\tau_k(n)}) \] and \[ \Delta y_n=b_ny_n+ \sum^n_{k =1} a_k(n) |y_{\tau_k(n)} |^{\alpha_k} \text{sgn} y_{\tau_k(n)}. \] The author obtains some asymptotic estimates of solutions for these equations.
