# GROUPS & RINGS - 2020/1

Module code: MAT2048

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.

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 grading and feedback. Verbal feedback is provided in lectures and office hours.

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

Overall student workload

Independent Study Hours: 117

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.
