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

$u\!+\!\mathrm i v=\mathrm{SuNem}_{1}(x\!+\!\mathrm i y)$

SuNem is superfunction for the Nemtsov function,

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

The map is symmetric with respect to reflection from the real axis; so, the only upper half of the complex plane is shown.
