二阶有理差分方程的复动力学

Complex Dynamics of a Second Order Rational Difference Equation

Sk Sarif Hassan, Anupam Bhandari

摘要:

研究了具有实参数$α$、$β$和任意非负实初始条件的二阶有理差分方程$\displaystyle{z_{n+1}=\frac{α+ z_{n-1}}{βz_n + z_{n-1}}}$的动力学问题。在本手稿中,考虑到参数$α$和$β$为复数并且初始值为任意复数,已经重新讨论了相同的问题。结果表明,某些结果在实直线上成立,但在复平面上不成立。得到了复参数差分方程的混沌解,但在实参数情况下不存在混沌解。

英文摘要:

The dynamics of the second order rational difference equation $\displaystyle{z_{n+1}=\frac{α+ z_{n-1}}{βz_n + z_{n-1}}}$ with the real parameter $α$, $β$ and arbitrary non-negative real initial conditions is investigated a decade ago. In the present manuscript, the same has been revisited considering the parameters $α$ and $β$ as complex numbers and the initial values as arbitrary complex numbers. It is found that some of the results which are valid in real line but does not valid in complex plane. The chaotic solutions of the difference equation with complex parameters are achieved, however there does not exists such solutions in the case of real parameters.
