Periodic solutions of a system of nonlinear difference equations with periodic coefficients

Durhasan Turgut Tollu

摘要:

本文讨论了如下差分方程组:x_{n+1} =((a_{n})/(x_{n}))+((b_{n})/(y_{n})),y_{n+1} =((c_{n})/(x_{n}))+((d_{n})/(y_{n})),n在N_0中,其中初始值x_0,y_0是正实数,并且系数(a_{n})_{n>=0},(b_{n})_{n>=0},(c_{n})_{n>=0},(d_{n})_{n>=0}是具有正项的双周期序列。该系统是所有正解都是双周期或收敛于其双周期解的系统的推广。本文通过一种新的求解方法,考察了该系统正解的长期行为。

英文摘要:

In this paper it is dealt with the following system of difference equations x_{n+1}=((a_{n})/(x_{n}))+((b_{n})/(y_{n})), y_{n+1}=((c_{n})/(x_{n}))+((d_{n})/(y_{n})), n in N_0, where the initial values x_0,y_0 are positive real numbers and the coefficients (a_{n})_{n>=0}, (b_{n})_{n>=0}, (c_{n})_{n>=0}, (d_{n})_{n>=0} are two-periodic sequences with positive terms. The system is an extention of a system that every positive solution is two-periodic or converges to its a two-periodic solution. Here, the long-term behavior of posistive solutions of the system is examined by using a new method to solve the system.
