where p_q(z) is a periodic function and Q is a constant.
Yes, first a (regular) superfunction is always undetermined by an x-axis shift, this is the role of Q.
Second if you have any two superfunctions f and g, then
\( g^{-1}(f(x)) \) (if g is suitably injective) is always a 1-periodic function, which follows from the definition of Abel and superfunction.
