GaloisTheory - University of Illinois Urbana-Champaign

faculty.math.illinois.edu

Galois theory is based on a remarkable correspondence between subgroups of the Galois group of an extension E/Fand intermediate fields between Eand F. In this section we will set up the machinery for the fundamental theorem. [A remark on notation: Throughout the chapter,the compositionτ σof two automorphisms will be written as a product τσ.]

2 Complex Functions and the Cauchy-Riemann Equations

www.math.columbia.edu

2 Complex Functions and the Cauchy-Riemann Equations 2.1 Complex functions In one-variable calculus, we study functions f(x) of a real variable x. Like-wise, in complex analysis, we study functions f(z) of a complex variable z2C (or in some region of C). Here we expect that f(z) will in general take values in C as well.

connection to complex analysis. The key connection to 18.04 is that both the real and imaginary parts of analytic functions are harmonic. We will see that this is a simple consequence of the Cauchy-Riemann equations. In the next topic we will look at some applications to hydrodynamics. 5.2 Harmonic functions

The real and imaginary parts of an analytic function are harmonic conjugate functions, i.e., solutions to Laplace equation and satisfy the Cauchy Riemann equations (2, 3). 3 Singularities of Analytic Functions Points at which a function f(z) is not analytic are called singular points or singularities of f(z). There are two different types of ...

It is also possible to show that if the Cauchy–Riemann equations hold at a point z, then f is differentiable there (subject to certain technical conditions on the continuity of the partial derivatives).

LECTURE 2: COMPLEX DIFFERENTIATION AND CAUCHY RIEMANN EQUATIONS 3 (1) If f : C → C is such that f0(z) = 0 for all z ∈ C, then f is a constant function. This is because, by CR equation u x = u y = v x = v y = 0. So by MVT of two variable calculus u and v are constant function and hence so is f.

3 Contour integrals and Cauchy’s Theorem 3.1 Line integrals of complex functions Our goal here will be to discuss integration of complex functions f(z) = u+ iv, with particular regard to analytic functions. Of course, one way to think of integration is as antidi erentiation. But there is also the de nite integral.
