Competencies

Non-official translation of the module descriptions. Only the German version is legally binding.

Students master the essential contents and methods of Representation Theory, in particular they can independently carry out very complex proofs in this area requiring a high level of mathematical expertise. The essential competences in Representation Theory include

  • Describe key concepts and definitions in the representation theory of finite-dimensional associative algebras.
  • Explain important theorems and results, and outline their proofs.
  • Compute the indecomposable projective and injective modules for an algebra given by a quiver with relations.
  • Compute Auslander-Reiten quivers by the so-called knitting method.
  • Classification of indecomposable representations for quivers of finite representation type.

Furthermore, the students recognise further-reaching connections to mathematical facts already acquired. They can transfer and apply the knowledge and methods they have learnt so far to deeper mathematical problem areas. Students also expand their mathematical intuition as a result of more intensive study.
In the tutorials, students develop their ability to discuss mathematical topics and thus further prepare themselves for the requirements of the Master's module, in particular for the scientific discussion within the Master's seminar presentation and the defence of their Master's thesis.

Content of teaching

The following basic content of teaching from the field of Representation Theory is compulsory:

  • Structure of finite-dimensional associative algebras
  • Representations of quivers
  • Auslander-Reiten sequences and the Auslander-Reiten quiver.

In addition, the following content of teaching can be covered, for example:

  • Quivers of tame representation type
  • (tau-)Tilting theory

Recommended previous knowledge

Linear algebra, Rings and modules, Homological algebra

Study requirements

Allocated examiner Workload LP2
Teaching staff of the course Tutorials Representation Theory 1 (exercise)

Regular completion of the exercises, each with a recognisable solution approach, as well as participation in the exercise groups for the module's lecture. As a rule, participation in the exercise group includes presenting solutions to exercises twice after being asked to do so as well as regular contributions to the scientific discussion in the exercise group, for example in the form of comments and questions on the proposed solutions presented. The organiser may replace some of the exercises with face-to-face exercises.
