Closed-form Iterative Roots of Power Functions
-
摘要: 研究了幂函数的迭代根. 首先给出了单调幂函数的闭形式迭代根,然后对于非单调幂函数的情形,通 过延拓的方法给出 了其闭形式迭代根.Abstract: Iterative roots of power functions were studied. First, a closed-form iterative root of monotonic power func-
tions was given,then a closed-form iterative root of non-monotonic power functions was given by extension method.
