  • Fundamentals of associative algebra theory.
  • artinian, noetherian, and semisimple moduli
  • semisimple algebras and Wedderburn's theorem.
  • Decomposition theory for moduli
  • projective moduli of right artinian algebras
  • quivers of right-artic algebras
  • Quiver representations

Qualification Goals

The students

  • understand beginnings of the theory of noncommutative algebras and their representations,
  • can transfer their skills in dealing with matrices to a more abstract context,
  • understand matrices as a special case of abstract algebraic structures,
  • have deepened mathematical working methods (developing mathematical intuition and its formal justification, abstraction, proof),
  • have improved their oral communication skills in lecture and tutorials by practicing free speech in front of an audience and in discussion.


None. The competences taught in the following modules are recommended: either Algebra [Bachelor Module] or Algebra [Lehramt Module].
