Consider the Ackermann successor function \[\varphi(u)\] such that \[\varphi(a \uparrow ^m b)=a \uparrow ^{m+1} b\]. Is \[\varphi(u)\] analytic? If so then the complex dynamics of \[\varphi^n(u)\] can be studied where there is a finite real fixed at point \[a\uparrow^\infty\infty\]. For example where \[1 \leq a < e^\frac{1}{e}\].
