## PURE MTH 3007 - Groups and Rings III

### North Terrace Campus - Semester 1 - 2020

The algebraic notions of groups and rings are of great interest in their own right, but knowledge and understanding of them is of benefit well beyond the realms of pure algebra. Areas of application include, for example, advanced number theory; cryptography; coding theory; differential, finite and algebraic geometry; algebraic topology; representation theory and harmonic analysis including Fourier series. The theory also has many practical applications including, for example, to the structure of molecules, crystallography and elementary particle physics. Topics covered are: (1) Groups, subgroups, cosets and normal subgroups, homomorphisms and factor groups, products of groups, finitely generated abelian groups, groups acting on sets and the Sylow theorems. (2) Rings, integral domains and fields, polynomials, ideals, factorization in integral domains and unique factorization domains.

• Learning Outcomes
##### Course Learning Outcomes
 1. Demonstrate understanding of the idea of a group, a ring and an integral domain, and be aware of examples of these structures in mathematics. 2. Appreciate and be able to prove the basic results of group theory and ring theory. 3. Understand and be able to apply the fundamental theorem of finite abelian groups. 4.

##### Recommended Resources
J. B. Fraleigh, “A first course in abstract algebra", Addison-Wesley, 7th edition, 2002; covers most of the material in the course in a similar manner to that presented in lectures.

M. A. Armstrong, "Groups and Symmetry", Springer, 1988; covers most of the material about groups in the course, but in addition has many geometric applications and examples.

There are many other introductory texts on abstract algebra in the library which students may find useful as references.
##### Online Learning
Assignments, tutorial exercises, handouts, and course announcements will be posted on MyUni.
• Learning & Teaching Activities
##### Learning & Teaching Modes
Lecture notes for the course will be made available to students, students will be expected to read over this material in advance. The lecturer guides the students through the course material in the lectures, working through proofs and examples. In particular students will have opportunity to raise any points of difficulty arising from their own reading of the notes. Whilst they will be recorded, students will not
gain the full benefit if not able to attend in person. Fortnightly homework assignments help students strengthen their understanding of the theory and their skills in applying it, and allow them to gauge their progress.

The information below is provided as a guide to assist students in engaging appropriately with the course requirements.

In weeks 2,4,6,8,10 and 12 there will be a tutorial in the Wednesday class.
There will be a mid semester test, most likely in the Wednesday class in week 7 after the mid semester break. There will be one meeting during one of the classes for discussions about the group project.
##### Small Group Discovery Experience
A group project with a written report develops research skills, teamwork skills, and communication skills.
• Assessment

The University's policy on Assessment for Coursework Programs is based on the following four principles:

1. Assessment must encourage and reinforce learning.
2. Assessment must enable robust and fair judgements about student performance.
3. Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
4. Assessment must maintain academic standards.

##### Assessment Summary
Examination Summative Examination period 60% All
Homework assignments Formative and summative Weeks 3,5,7,9,11 15% All
Mid semester test Summative Week 7 15% All
Group Project Formative and summative Week 10 10% All
Due to the current COVID-19 situation modified arrangements have been made to assessments to facilitate remote learning and teaching. Assessment details provided here reflect recent updates.

The modified assessment arrangements and the weighting for each component for this course are as follows:

50% exam, administered online during the usual exam period
30% assignments, this means each of the 5 assignments counts for 6%, timing of the assignments as announced in the course outlineLinks to an external site.
20% individual project, to be announced in week 6 and due in week 12.
The mid semester test is cancelled and the group project replaced by an individual project.
##### Assessment Related Requirements
An aggregate score of 50% is required to pass the course.
##### Assessment Detail
Assignment 1 Week 1 Week 3 3%
Assignment 2 Week 3 Week 5 3%
Assignment 3 Week 5 Week 7 3%

##### Submission

Homework assignments must be given to the lecturer in person or emailed as a pdf. Failure to meet the deadline without reasonable and verifiable excuse may result in a significant penalty for that assignment.  Assignments will be returned within two weeks.

Students may be elegible for an extension or exemption from an assignment for medical or compassionate reasons. Documentation is required and the lecturer must be notified as soon as possible.

Grade Descriptors are available which provide a general guide to the standard of work that is expected at each grade level. More information at Assessment for Coursework Programs.

Final results for this course will be made available through Access Adelaide.

• Student Feedback

The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.

SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

• Student Support
• Policies & Guidelines
• Fraud Awareness

Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's studentâ€™s disciplinary procedures.

The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
