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.


None. The competences taught in the following modules are recommended: either Linear Algebra I and Linear Algebra II or Basic Linear Algebra, either Analysis I and Analysis II or Basic Real Analysis, either Elementary Algebraic Geometry or Algebra.
