Also one assumes you are only interested in this limit for exp(-e)<=a<=exp(1/e),

otherwise it is not defined. if exp(-e)<=a<=exp(1/e), then it is the real attracting fixed point of a^L=L. Is this a correct understanding of your intentions?

Well, first of all, f(x) is any function, it can be x^2+3, cos(x), x, ... etc.

No, I have not tried iterate f(x) (functionally like f^oN), because these formulas are based on the iteration of addition (multiplication, exponentiation,...etc.), but I could try it, why not?

In fact it is not the lim h->infinity a^^h, because that is equals to W(-ln(a))/-ln(a). I have been looking for lim h->0 super h-th root of a.

You know, x^^(1/y) is not super y-th root of x, right?

This is my big problem, but I believe it might be our advantage.
