The two regular super-exponentials to base exp(1/e) are constructed. An efficient algorithm for the evaluation of these super-exponentials and their inverse functions is suggested and compared to the already published results.
We introduce the intuitive method to select an analytic Abel function of an analytic function f at a non-fixpoint. Due to the complexity of this method by involving matrix inversion of increasing size there is little known about its convergence. We show its convergence in the simplest but still complicated case f(x)=bx. We show that the obtained Abel function is, as expected, the logarithm to base b, independent on its development point. As a by-product we obtain a new polynomial approximation sequence for the logarithm to base b.
We give a simple uniqueness criterion (and some derived criteria) for holomorphic Abel functions and show that Kneser's real analytic Abel function of the exponential is subject to this criterion.
