GALOIS THEORY - 2019/0
Module code: MAT3011
In light of the Covid-19 pandemic the University has revised its courses to incorporate the ‘Hybrid Learning Experience’ in a departure from previous academic years and previously published information. The University has changed the delivery (and in some cases the content) of its programmes. Further information on the general principles of hybrid learning can be found at: Hybrid learning experience | University of Surrey.
We have updated key module information regarding the pattern of assessment and overall student workload to inform student module choices. We are currently working on bringing remaining published information up to date to reflect current practice in time for the start of the academic year 2021/22.
This means that some information within the programme and module catalogue will be subject to change. Current students are invited to contact their Programme Leader or Academic Hive with any questions relating to the information available.
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.

|Assessment type||Unit of assessment||Weighting|
|School-timetabled exam/test||IN-SEMESTER TEST (50 MINS)||20|
|Examination||EXAMINATION (2 HOURS)||80|
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 instant grading and immediate feedback. Verbal feedback is provided in lectures and office hours.
- 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.
|1||Demonstrate a deeper appreciation of algebraic structures and of the power of linking different structures||KCT|
|2||Solve cubic and quartic equations, understanding the limitations of the methods||KC|
|3||Evaluate the degree of finite field extensions and apply this to algebraic and geometric examples||KC|
|4||Evaluate specific Galois groups and relate their structure to that of field extensions and to the solvability of polynomial equations .||KC|
|5||Construct simple proofs similar to those encountered in the module.||KCT|
C - Cognitive/analytical

P - Professional/Practical skills
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.
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
