Based upon ideas similar to my recent TPID 4 proof , and knesers sexp , I came close to a proof (imho) and now conjecture :
There is a semistrip on the complex plane , parallel and symmetric to the real line , that includes \( +oo \) with \( -\pi/4 < \) \( Im \) \( < \pi/4 \) such that exp^[1/2+eps](z) has no singularities for z in that strip.
(of course eps > 0 and real as usual.)
