摘要 考虑一类推广后的Feigenbaum函数方程其中h(x)是[-1,1]上的递减光滑奇函数且满足h(0)=0,-1<h′(x)<0,x∈[-1,1].利用构造性方法讨论上述方程的光滑解的存在性及唯一性. This work focuses on a class of generalized Feigenbaum's functional equations {g(0)=1,-1≤g(x)≤1,x∈[-1,1],h(g(x))=g(g(h(x)))where h(x) is C∞-decreasing odd function on [-1, 1] and satisfies h(O) = 0,-1 〈 h'(x) ,〈 0,x ∈ [-1, 1]. Using constructive methods, we discuss the existence and uniqueness of C∞-solutions of the above equation.
