摘要
在本研究中,我们开发了获得逻辑映射Tr中任意目标不动点的同斜分岔参数的方法。我们考虑了Tr在x = 0.5附近的几何结构,并推导了分岔发生的核心条件。通过数值实验,我们计算出了l≤256时T l r不动点的精确分岔参数。我们还讨论了在分岔参数和不动点坐标序列中发现的Feigenbaum常数。这一事实意味着不动点的局部稳定性和它周围的全局结构通过常数联系在一起。
In this study, we have developed the method to obtain the homoclinic bifurcation parameter of an arbitrary targeted fixed point in the logistic map Tr. We have considered the geometrical structure of Tr around x = 0.5 and derived the core condition of the bifurcation occurrence. As the result of numerical experiment, we have calculated the exact bifurcation parameter of the fixed point of T l r with l ≤ 256. We have also discussed the Feigenbaum constants found in the bifurcation parameter and the fixed point coordinate sequences. This fact implies the local stability of the fixed point and global structure around it are in association via the constants.
