Webthere is no point z0 in D such that If(z) I < jf(zo) j for all z in D. This immediately follows from the Open Mapping Theorem since, in particular, f(D) is open and, thus, to each point wo = f(z0) in f(D) there is a neighborhood N of w0 contained in f(D). It is clear that some points w =f(z) in N satisfy j w j > j wj . Such points are illus- WebTherefore, f satisfies the Cauchy-Riemann equations and has an antiderivative F. This antiderivative is necessarily of the form u+iv(x,y) for some x,y since ∂F ∂z = ∂F ∂x. So we have the equation ∂Ref ∂x +i ∂Imf ∂x = ux −iuy. So equating real parts, we get ux = ∂Re(F) ∂x. But the real part of this derivative of F is ∂u ...
