While I have looked for a simple way to move between Abel's and Schroeder's equations, they are not topologically conjugate.

This is the complex valued superfunction, which you are familiar with

Kneser's would take the Schroeder function of the real valued tetration function, to get what he called the Chi-Star function; but I was actually showing my construction, and its equivalence to Kneser's; see my last post showing the Riemann mapping to a circle. As far as the topologically conjugate issue, yes the complex valued superfunction is Periodic in the complex plane with period~= 4.447 + 1.058i, so it is not one to one. You have to be consistent with your branch to get the real valued sexp(z) via the theta(z) function. Knesser's Riemann mapping for that matter, must also be consistent. But the periodicity of the complex valued superfunction is not an issue. And in fact, Kneser's tetration solution is psuedo periodic with a pseudo period approaching arbitirarily closely to the period of the complex valued superfunction as imag(z) increases.
