• Module code: MA377
• Module name: Rings and Modules
• Department: Mathematics Institute
• Credit: 15

## Module content and teaching

###### Principal aims

A ring is an important fundamental concept in algebra and includes integers, polynomials and matrices as some of the basic examples. Ring theory has applications in number theory and geometry. A module over a ring is a generalization of vector space over a field. The study of modules over a ring R provides us with an insight into the structure of R. In this module we shall develop ring and module theory leading to the fundamental theorems of Wedderburn and some of its applications.This module aims to realise the importance of rings and modules as central objects in algebra and to study some applications.

###### Principal learning outcomes

By the end of the course the student should understand:The importance of ring as a fundamental object in algebra; The concept of a module as a generalisation of a vector space and an Abelian group; Constructions such as direct sum, product and tensor product; Simple modules, Schur's lemma; Semisimple modules, artinian modules, their endomorphisms. Examples; Radical, simple and semisimple artinian rings. Examples; The Artin-Wedderburn theorem; The concept of central simple algebras, the Brauer group.
