两个非单调点PM函数的非单调高度

众所周知,单调函数的非单调高度都为0,而对于非单调的函数,情况将变得非常复杂。由于非单调高度的变化影响迭代根的构造,因此在动力系统的研究中具有重要的意义。将在之前N型PM函数的非单调高度研究的基础上,继续讨论两个非单调点PM函数的非单调高度分类,得到此类函数高度的完整分析,并以此研究其动力学性质。
Nonmonotonicity Height of PM Functions with two Non-Monotone Points
It is well known that the nonmonotonicity height of each monotone function is zero.However,the situation is very complicated for non-monotone functions.Since the variation of nonmonotonicity height is related to the construction of iterative roots,it be-comes an important subject in dynamical systems.Based on the previous work about N-type PM functions,we continue to discuss the classification of nonmonotonicity height for PM functions with two non-monotone points,and then a completed analysis of nonmonotonicity height is given for such functions,which helps to study their dynamic properties.
