K周期系数差分方程xn＋1=pn＋xn-3s-2/xn-s的动力学性质

On the Dynamics of x_(n+1)=p_n+(x_(n-3s-2))/(x_(n-s)) with a Period-k Coefficien

研究非自制差分方程x_(n+1)=p_n+(x_(n-3s-2)/x_(n-8)),其中p_n>0是一K周期序列.最后得到了方程解的有界性的一些充分条件.

In this paper, we consider the boundedness character of solutions of the nonautonomous difference equation xn＋1=pn＋xn-3s-s/xn-s, where the parameter pnis a period-k sequence, with positive values and the initial conditions axe positive.
