Course description and aims
The main topic of this course is representation theory of quivers. The representation theory of quivers can be thought of as an extension of linear algebra, and can be regarded as a part of representation theory of associative algebras. In the study of representation theory of quivers, we essentially use various mathematical tools such as category theory, homological algebra, and geometry. The representation theory of quivers has applications in many fields, including the theory of cluster algebras and the representation theory of Lie algebras and quantum groups.
Following "Advanced topics in Algebra G", the aim of this course is to introduce the basic notions in the representation theory of quivers and to explain its applications. In particular, the latter half of the course will focus on explaining the breadth of representation theory of quivers, not in the form of explaining the details of proofs, but in the form of introducing many topics. Through this course, students are expected to learn that various mathematical tools are essentially used in the representation theory.
Student learning outcomes
- To be able to explain the definition of Auslander–Reiten quivers of finite dimensional K-algebras
- To be able to write an example of an Auslander–Reiten quiver of a finite dimensional K-algebra
- To be able to explain applications of representation theory of quivers to other fields.
