MAT1031 Algebra

Module overview

This module provides an introduction to abstract algebra through elementary group and ring theory.  Thus it forms the starting point for all the algebraic modules that follow: MAT2005 Algebra and Codes, MAT3011 Galois Theory, MAT3032 Advanced Algebra and MATM011 Lie Algebras.

Module aims

introduce the axiomatic approach to group theory and ring theory

develop confidence in working with algebraic structures

provide a firm foundation for subsequent study of abstract algebra

Module content

Indicative content includes:

Revision of the group axioms, permutations and the integers modulo n.
Symmetries and the dihedral groups.
Cyclic groups, direct products.
Group homomorphisms and isomorphisms.
Cosets, normal subgroups, quotient groups. Lagrange's theorem.
Introduction to rings and fields.  Subrings, ideals and quotient rings.

Methods of Teaching / Learning

The learning and teaching strategy is designed to provide:

An introduction to algebraic structure theory
Experience of the methods used to interpret, understand and solve problems in group and ring theory

The learning and teaching methods include:

Three 50-minute lectures per week for eleven weeks, some being used as tutorials, problem classes and in-semester tests.
Online notes supplemented by additional examples in lectures.
Two unassessed coursework assignments, marked and returned.
Personal assistance given to individuals and small groups in office hours.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate their ability to

·         construct and interpret mathematical arguments in the context of this module;

·         display subject knowledge by recalling key definitions and results;

·         apply the techniques learnt to both routine and unfamiliar problems.


Thus, the summative assessment for this module consists of:

·         One two-hour examination at the end of Semester 1, worth 80% of the module mark.

·         In-semester test, worth 20% of the module mark.


Formative assessment and feedback

Students receive written comments on their marked coursework assignments.  Maple TA may be used in assignments to provide immediate is used for part of the assignments and provides instant grading and feedback.s to solve problemsials, complex numbers,grading and feedback.  Verbal feedback is provided in lectures and office hours.
