PURE MTH 7059 - Groups & Rings

North Terrace Campus - Semester 1 - 2017

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 Resources
    Required Resources
    Recommended Resources
    J. B. Fraleigh, “A first course in abstract algebra", covers most of the material in the course in a similar manner to that presented in lectures. 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
    A complete set of notes for the course will be made available to students at the start of semester.
    Each week the lecturer will indicate which material will covered, students will be expected to read over this material in advance and the lecture time will be used to guide the class through the material, 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. These classes are intended to have a high level of interaction, whilst they will be recorded, students will not gain the full benefit if not able to attend in person.
    The material is challenging and students are not expected to be able to learn it based solely on their own study.
    The third class each week will be a tutorial focusing on problem solving, involving a combination of students working in groups, and the lecturer presenting solutions. There will be some slight variation to the schedule accomodate public holidays and the mid-semester tests.

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

  • 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.

  • 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 student’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.
