Complex map of function SuNem with parameter $q\!=\!1$;

$u\!+\!\mathrm i v=\mathrm{SuNem}_1(x\!+\!\mathrm i y)$

Description

Nemtsov function is polynomial of the special kind,

$\mathrm{Nem}_q(z)=z+z^3+qz^4$

where $q$ is positive parameter.

For the Nemtsov function, its superfunction SuNem is solution $F=\mathrm{SuNem}_q$ of the transfer equation

$F(z\!+\!1)=\mathrm{Nem}_q(F(z))$

whit specific behaviour at -infinity

$\displaystyle \mathrm{SuNem}_q(z) = \frac{1}{\sqrt{-2z}} \left(1+O\left( \frac{1}{\sqrt{-2z}} \right)\right)$

and specific value at zero, $\mathrm{SuNem}_q(0)=1$.

The Nemtsov function is suggested as an example of the transfer finction, for wich the exotic iterates cannot be constructed with algorithms, presented in the First Russian version of the book Superfunctions.
