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.
