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.]

The absolute value measures the distance between two complex numbers. Thus, z 1 and z 2 are close when jz 1 z 2jis small. We can then de ne the limit of a complex function f(z) as follows: we write lim z!c f(z) = L; where cand Lare understood to be complex numbers, if the distance from f(z) to L, jf(z) Lj, is small whenever jz cjis small.

7.2. The complex plane. Just as real numbers can be visualized as points on a line, complex numbers can be visualized as points in a plane: plot x+ yiat the point (x;y). Addition and subtraction of complex numbers has the same geometric interpretation as for vectors. The same holds for scalar multiplication of a complex number by a real number.
