Contents
- polynomials in several variables,
- splitting fields, algebraic closure, Steinitz's theorem,
- Normal, separable and inseparable field extensions,
- Galois extensions, fundamental theorem of Galois theory,
- Computation of the Galois group, translation theorem,
- Finite fields, roots of unity, cyclotomic polynomials,
- Pure equations, cyclic Galois groups,
- solubility of algebraic equations by radicals (in any characteristic), constructions with compass and ruler, regular n-gons
Qualification Goals
The students
1. get to know Galois theory and its applications and, in particular, are able to assess its historical significance,
2. learn how elementary questions about geometric constructions and solving equations can be approached by abstract algebraic methods,
3. train the use of algebraic methods using many concrete examples,
4. practice mathematical methods (development of mathematical intuition and its formal justification, training of the ability to abstract, proof methods),
5. improve their oral communication skills in the recitation classes by practicing free speech in front of an audience and during discussion.
Prerequisites
Translation is missing. Here is the German original:
Keine. Empfohlen werden die Kompetenzen, die in den Basismodulen und im Aufbaumodul Algebra vermittelt werden.
