Given the mathematics, I think the domain in the draft is wrong and should
have read 'finite non-zero x'
As the special case in
a) the 6th bullet point says 'finite non-zero x x', it is not out of
the realm of possibility that the domain in that 5th point is a typo
b) an earlier bullet point has a domain 0 + I * INFINITY overlaps, which
it must not, then this 'positive finite x' is highly questionable
Thanks - Damian
