# MATHS 320 : Algebraic Structures

## Science

### Course Prescription

This is a framework for a unified treatment of many different mathematical structures. It concentrates on the fundamental notions of groups, rings and fields. The abstract descriptions are accompanied by numerous concrete examples. Applications abound: symmetries, geometry, coding theory, cryptography and many more. This course is recommended for those planning graduate study in pure mathematics.

### Course Overview

This course is intended for students who have enjoyed the examples of algebraic structures presented in MATHS 254/255, 253 and/or MATHS 328, and who are interested in a unified treatment of many different mathematical structures. The main focus of the course is on the fundamental algebraic structures of groups, rings and fields. The abstract descriptions are accompanied by numerous concrete examples. Emphasis is placed on the contexts in which basic structures occur, methods by which they can be modelled and analysed, and their diverse applications. This course is recommended for those planning graduate study in pure mathematics. A student completing this course will have a basic knowledge of the fundamental of algebraic systems, and be able to construct simple proofs in an algebraic setting and appreciate the strength the strength of abstract algebraic methods.

### Learning Outcomes

By the end of this course, students will be able to:
1. Display basic knowledge of fundamental algebraic systems: groups, rings and fields and their properties by solving relevant questions and examples (Capability 1 and 2)
2. Display ability to analyse and answer questions, through examples and methods (Capability 1, 2 and 3)
3. Demonstrate understanding of connections with other disciplines and real world applications by the use of relevant examples (Capability 1, 2, 3 and 4)
4. Demonstrate understanding of the nature of proof and precision in mathematics, and the ability to present arguments both formally and informally in written form (Capability 2, 4 and 5)

### Special Requirements

This course has no special requirements.

This course is a standard [15] point course and students are expected to spend 10 hours per week involved in each 15 point course that they are enrolled in.

For this course, you can expect [36] hours of lectures, a [11] hour tutorial, [36] hours of reading and thinking about the content and [67] hours of work on assignments and/or test preparation.

### Delivery Mode

#### Campus Experience

Attendance is [expected] at scheduled activities including [tutorials] to [receive credit for] components of the course. However it will be available for remote students with special circumstances (for example those outside New Zealand).

Lectures will be available as recordings, however students should be aware that it is not always possible to record material written on the whiteboards. Other learning activities including tutorials will not be available as recordings.

Attendance on campus is [required] for the [test] at the COVID alert level 1 and the test is online at levels 2, 3, 4.

The exam  in 2021 is online.

The activities for the course are scheduled as a weekly timetable delivery.

### Learning Resources

The recommended textbook is "Contemporary Abstract Algebra", by J. A. Gallian (published by D.C. Heath & Company), 8th edition or later, but also detailed course notes will be provided, and these will include definitions, examples, properties and applications of the key concepts developed in the course.

### Student Feedback

During the course Class Representatives in each class can take feedback to the staff responsible for the course and staff-student consultative committees.

At the end of the course students will be invited to give feedback on the course and teaching through a tool called SET or Qualtrics. The lecturers and course co-ordinators will consider all feedback.

Your feedback helps to improve the course and its delivery for all students.

### Digital Resources

Course materials are made available in a learning and collaboration tool called Canvas which also includes reading lists and lecture recordings (where available).

Please remember that the recording of any class on a personal device requires the permission of the instructor.

The University of Auckland will not tolerate cheating, or assisting others to cheat, and views cheating in coursework as a serious academic offence. The work that a student submits for grading must be the student's own work, reflecting their learning. Where work from other sources is used, it must be properly acknowledged and referenced. This requirement also applies to sources on the internet. A student's assessed work may be reviewed against online source material using computerised detection mechanisms.

You may copy the course content for the purposes of private study or research, but you may not upload onto any third party site, make a further copy or sell, alter or further reproduce or distribute any part of the course content to another person.

### Inclusive Learning

All students are asked to discuss any impairment related requirements privately, face to face and/or in written form with the course coordinator, lecturer or tutor.

Student Disability Services also provides support for students with a wide range of impairments, both visible and invisible, to succeed and excel at the University. For more information and contact details, please visit the Student Disability Services’ website

### Special Circumstances

If your ability to complete assessed coursework is affected by illness or other personal circumstances outside of your control, contact a member of teaching staff as soon as possible before the assessment is due.

If your personal circumstances significantly affect your performance, or preparation, for an exam or eligible written test, refer to the University’s aegrotat or compassionate consideration page .

This should be done as soon as possible and no later than seven days after the affected test or exam date.

### Learning Continuity

In the event of an unexpected disruption we undertake to maintain the continuity and standard of teaching and learning in all your courses throughout the year. If there are unexpected disruptions the University has contingency plans to ensure that access to your course continues and your assessment is fair, and not compromised. Some adjustments may need to be made in emergencies. You will be kept fully informed by your course co-ordinator, and if disruption occurs you should refer to the University Website for information about how to proceed.

With respect to the COVID alert levels this course will be delivered in the following fashion.
Level 1:  Delivered normally as specified in delivery mode
Level 2: You will not be required to attend in person.  All teaching and assessment will have a remote option.
Level 3 / 4: All teaching activities and assessments are delivered remotely
