Galois theory: algebraic field extensions, constructions with ruler and compass, normal and separable field extensions, cyclotomic polynomials, finite fields, solvable groups, symmetric polynomials, fundamental theorem of Galois theory, solvability of algebraic equations

Algebraic varieties: Affine varieties and Hilbert Nullstellensatz, Morphisms of Affine Varieties, Rational Functions and maps, Smooth Points, Tangent Spaces and Dimensions

Qualification Goals

The students shall

  • learn the essential features of Galois theory and its applications and appreciate its historical significance,
  • learn about the applicability of algebraic methods for the description of geometric objects (algebraic varieties),
  • Understand the translation process between geometry and algebra and be able to apply it to posed problems,
  • practice mathematical working methods (development of mathematical intuition and its formal justification, training of the ability to abstract, proof techniques),
  • improve their oral communication skills in the exercises by practicing free speech in front of an audience and during discussion.


Translation is missing. Here is the German original:

Keine. Empfohlen werden die Kompetenzen, die in den Basismodulen sowie im Aufbaumodul Elementare Algebraische Geometrie oder im Aufbaumodul Algebra vermittelt werden.


The module can be attended at FB12 in study program(s)

  • B.Sc. Mathematics
  • M.Sc. Computer Science
  • M.Sc. Mathematics
  • LAaG Mathematics

When studying M.Sc. Mathematics, this module can be attended in the study area Specialization Modules in Mathematics.

The module can also be used in other study programs (export module).

Die Wahlmöglichkeit des Moduls ist dadurch beschränkt, dass es der Reinen Mathematics zugeordnet ist.
