摘要
给出了共轭方程φ(f(x))=f(φ(x))在f和g严格递减的情况下其单调递减根存在性的条件,并利用此结果研究了一类有两个非单调点的函数迭代根的存在性.
The existence of decreasing roots of the conjugate function φ(f(x))=g(φ(x)) is discussed when f and g are decreasing,and the existence of iterative roots of one kind of functions which have two non-monotone points is studied.
