AuPow is specific Abelpower function, id est, the specific Abel function for the Power function.

AuPow can be expressed as elementary function,


Where $a$ is parameter. Usually, it is assumed that $a\!>\!0$.

AuPow is inverse function of SuPow, that, in its turn, is superfunction of the power function.


AdPow and AuPow

Another abelfunction for the power function is called AdPow;


AdPow is related with AuPow function with simple relation:


For $a\!=\!2$, both functions AdPow and AuPow are shown in Fig.1

For the same $a\!=\!2$, complex map of function AuPow is shown in Fig.2.

Inverse function

For AuPow, the inverse function is SuPow, that is superpower function, id est, superfunction of the power function:


SuPow satisfies the Transfer equation


SuPow is elementary function,

$\mathrm{SuPow}_a(z)= \exp(a^z)$


AuPow appears as example of the Abel function that can be expressed as elementary function. This allows to trace evaluation of superfunction through the regular iteration; the fixed point unity can be used for the calculation.

This example seems to be important for the book Superfunctions.
