3) holds at P , then f has a complex derivative at P . Thus a C 1 function that is conformal in either sense at all points of an open set U must possess the complex derivative at each point of U . Then f is holomorphic if it is C 1 . We leave the proof of these assertions to the reader. ✐ ✐ ✐ ✐ ✐ ✐ “master” — 2010/12/8 — 16:23 — page 26 — #44 ✐ ✐ 26 A Guide to Complex Variables It is worthwhile to consider the theorem expressed in terms of real functions. We write f D u C iv; where u; v are real-valued functions.

2. 6). In fact this power series property is a complete characterization of holomorphic functions; we shall discuss it in detail below. The use of “differentiable” derives from properties related to the complex derivative. These pieces of terminology and their significance will be sorted out as the book develops. ” “Conformality” is an important geometric property of holomorphic functions that make these functions useful for modeling incompressible fluid flow and other physical phenomena. 5. See also [KRA6].

4. One derives this more general version of Cauchy’s formula with the standard device of deformation of curves. 4). Simple connectivity is a mathematically rigorous condition that corresponds to the intuitive notion that the region U has no holes. If U is simply connected, and is a closed curve in U , then it follows that can be continuously deformed to lie inside a disc in U . 4.
