  • Basic representation theory of quivers and algebras: representations, Jordan-Hölder Theorem, etc.
  • Basic category theory: categories, functors, natural transformations, limits, colimits, etc.
  • Basic homological algebra: exact sequences, complexes, (co-)resolutions, Ext and Tor, etc.

Basic knowledge of derived categories of abelian categories or of triangulated categories will not be assumed, but will be helpful.


The course will consist on a (biased) introduction to the representation theory of differential graded algebras with a particular focus on some of its applications to representation theory of quivers and algebras.


Lecture notes will be made available online as the course progresses. Recommended complementary literature will be included in the notes.
