Webh(z) = p z(z −1). Notice, however, that it is positive both above one and below zero. Furthermore, the branch structure is quite diﬀerent. This may be seen by writing it as h(z) = r (z − 1 2)2 − 1 4. This has a cut when when z = x is real and in the unit interval, but also when z − 1/2 = iy is pure imaginary. Thus there is a second ...
