GROUPS & RINGS - 2021/2
Module code: MAT2048
In light of the Covid-19 pandemic, and in a departure from previous academic years and previously published information, the University has had to change the delivery (and in some cases the content) of its programmes, together with certain University services and facilities for the academic year 2020/21.
These changes include the implementation of a hybrid teaching approach during 2020/21. Detailed information on all changes is available at: https://www.surrey.ac.uk/coronavirus/course-changes. This webpage sets out information relating to general University changes, and will also direct you to consider additional specific information relating to your chosen programme.
Prior to registering online, you must read this general information and all relevant additional programme specific information. By completing online registration, you acknowledge that you have read such content, and accept all such changes.
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.

|Assessment type||Unit of assessment||Weighting|
|School-timetabled exam/test||IN-SEMESTER TEST (50 MINS)||20|
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 grading and feedback. Verbal feedback is provided in lectures and office hours.
- 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

Lecture Hours: 33
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.
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.
