Title
Auslander-Reiten translation and $\tau$-tilting theory

 

Abstract
In the representation theory of finite dimensional algebras, Auslander-Reiten (AR) translation is an important tool to understand the modules. In these lectures, I first recall some basic properties of algebras including quiver representations. Then, I will explain some properties and explicit calculations of AR translation. After that, I would like to show you how AR translation is related to classical tilting theory and $\tau$-tilting theory.
