Course Objective

The aim of this course is to introduce the fundamental concepts in algebras and quiver representations.

Learning Outcomes of the Course Unit

1   Will be able to identify main kinds of algebras like semisimple algebras, central simple algebras, separable algebras, Quasi-Frobenious algebras and serial algebras.
2   Will be able to use representations of algebras and groups.
3   Will be able to understand how the study of finite-dimensional algebras over a field reduces to the study of bound quiver algebras.
4   Will be able to understand how Gabriel s Theorem gives the indecomposable representations by roots of associated quadratic forms for a connected quiver with finite representation type.
5   Will be able to use Auslander-Reiten quiver of a finite dimensional algebra A to approximate the category of A-modules.
