Algebraic Geometry: Projective Varieties
(dt. Algebraische Geometrie: Projektive Varietäten)

Level, degree of commitment Specialization module, depends on importing study program
Forms of teaching and learning,
Lecture (4 SWS), recitation class (2 SWS),
270 hours (90 h attendance, 180 h private study)
Credit points,
formal requirements
9 CP
Course requirement(s): Written or oral examination
Examination type: Successful completion of at least 50 percent of the points from the weekly exercises.
The grading is done with 0 to 15 points according to the examination regulations for the degree program M.Sc. Mathematics.
Origin M.Sc. Mathematics
One semester,
Regularly alternating with other specialization modules in Geometrie
Person in charge of the module's outline Prof. Dr. Thomas Bauer


Algebraic varieties: Affine and projective varieties, Hilbert's Nullstellensatz, singularities, tangent spaces and dimensions

Morphisms of varieties: regular and rational functions and maps, blow-up and resolution of singularities

Geometric applications: Linear systems of plane curves, cubic surfaces in three-space

Advanced algebro-geometric techniques: Divisors, differential forms, Riemann-Roch theorem on curves

Qualification Goals

The students shall

  • learn about the application of algebraic methods for the description of geometric objects (algebraic varieties),
  • understand the geometry-algebra-geometry translation process and be able to apply it to presented problems,
  • learn how geometric problems can be solved by using abstract algebraic techniques,
  • to develop their capacity for abstraction,
  • be introduced to current developments and results by learning modern methods of algebraic geometry,
  • 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.

Please note:

This page describes a module according to the latest valid module guide in Winter semester 2018/19. Most rules valid for a module are not covered by the examination regulations and can therefore be updated on a semesterly basis. The following versions are available in the online module guide:

The module guide contains all modules, independent of the current event offer. Please compare the current course catalogue in Marvin.

The information in this online module guide was created automatically. Legally binding is only the information in the examination regulations (Prüfungsordnung). If you notice any discrepancies or errors, we would be grateful for any advice.
