Course content

The content of the course may vary, but the core will consist of representations of quivers, path algebras, artinian, noetherian and local rings, projective and injective modules, the Jordan-Hölder Theorem, radical of modules and rings, socles, exact sequences, categories, functors, equivalence, and duality.

Learning outcome

1. Knowledge. The student masters the connection between module theory over finite dimensional algebras and representations of quivers. The student has basic knowledge of categories, functors, radical, base, and exact sequences. The student understands the Jordan-Hölder theorem and the Krull-Schmidt theorem.

2. Skills. The student is able to find radicals, bases etc. for special classes of finite dimensional algebras. The student is able to describe the corresponding module if a representation is given, and vice versa. The student is able to find the projective cover of a representation, and to calculate almost exact splitting sequences for given finite dimensional algebras.

Learning methods and activities

Lectures. The lectures will be given in English if they are attended by students from the Master's Programme in Mathematics for International students.
