MATHS 721 : Representations and Structure of Algebras and Groups
Science
2020 Semester Two (1205) (15 POINTS)
Course Prescription
Course Overview
This course is intended for students who have enjoyed the introduction to abstract algebra and parts of groups and rings presented in MATHS 255 / 254 / 320 / 326 / 328.
The main focus of the course is on structural properties and actions on abelian groups/vector spaces, and illustrating their fundamental role in the study of the structure of algebras and groups: for example, the character, module and ring approaches. Emphasis is placed on the contexts in which these structures occur, methods by which they can be modelled and analysed, and their diverse applications. We introduce students to some of the major results in the area: for example, the Wedderburn and Krull-Schmidt theorems.
A student completing this course will have a good knowledge of foundations of representation theory, its connections and applications and approaches in this field of growing importance. This is a core mathematics course for the BSc (Hons) and PGDipSci. It is also important to student wishing to pursue other graduate level courses in pure mathematics, and for those wishing to pursue graduate education in mathematics.

Learning Resources
Workload Expectations
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 [3] hours of lectures and [5] hours of reading and thinking about the content each week. You can expect [5] hours of work on each of the [4] assignments and exam preparation.
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.
Copyright
The content and delivery of content in this course are protected by copyright. Material belonging to others may have been used in this course and copied by and solely for the educational purposes of the University under license.
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.
Academic Integrity
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.
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 at http://disability.auckland.ac.nz
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: https://www.auckland.ac.nz/en/students/academic-information/exams-and-final-results/during-exams/aegrotat-and-compassionate-consideration.html.
This should be done as soon as possible and no later than seven days after the affected test or exam date.
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.
Student Charter and Responsibilities
The Student Charter assumes and acknowledges that students are active participants in the learning process and that they have responsibilities to the institution and the international community of scholars. The University expects that students will act at all times in a way that demonstrates respect for the rights of other students and staff so that the learning environment is both safe and productive.
