lemma 1

let f(z) be a real entire function with 2 conjugate fixpoints and no other fixpoints.

we define sf(z) as its superfunction and isf(z) as its inverse superfunction.

z and k are complex numbers.

if sf(isf(z) + k) is analytic with respect to z then it is also analytic with respect to k.

which superfunction?
