单峰映像相序的非负性

Nonnegative phase order of unimodal map

以逻辑斯蒂映像和帐篷映像为例研究了单峰映像的方向相,通过理论与数值的方法详细分析了系统的运动轨道及系统状态的不变测度,从而证实一般单峰映像都具有非负相序这一普适特性.

The direction phase of unimodal map is investigated by the example of logistic map and tent map.Based on the analytical and numerical method the traj ectory and invariant density of system states are studied.It can be confirmed that the phase order is nonnegative for general uni-modal map.
