Mathematica 7.0.1 gives (as InputForm of the result):
Element[C, Integers] && E^z != 0 && w == (2*I)*Pi*C + Log[E^z]
How can Mathematica be forced to simplify this to what is the fact,
namely, the following?
Element[C, Integers]&& w == (2*I)*Pi*C + z
(At the very least, certainly the expression E^z != 0 is redundant.)
