Also to warn others , I want to mention gottfriend " dream of a sequence " again.
It " pseudofactors " the exp(z).
Why does that matter ? Well because theorems about stable polynomials assume factorizations to hold everywhere.
Hence the analogue theorems for (stable) Taylor series might fail strongly !
