Module overview

Galois Theory applies the principles of algebraic structure to questions about the solvability of polynomial equations. The feasibility of certain geometrical constructions is also considered.

Module aims

review the theory of groups, rings, fields and polynomials.

develop and apply the theory of field extensions and Galois groups.

show the power of abstract algebra to produce practical and applicable results.

Module content

Indicative content includes:

Theory of polynomials.  Criteria for irreducibility.
Solution of cubic and quartic equations.
Field extensions. The degree of an extension.  The Tower law.
Geometric constructions.
Field automorphisms and their properties.
The Galois correspondence and the fundamental theorem.
Solvable groups.  Conditions for solvability of polynomials by radicals.

Methods of Teaching / Learning

The learning and teaching strategy is designed to provide:

An awareness of the applicability of abstract algebra to classical problems.
Knowledge of the historical context in which the subject material was developed.
Experience of the methods used to interpret, understand and solve problems in Galois 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.
