The module introduces the key abstract algebraic objects of groups, rings and fields and develops their fundamental theory. The theory will be illustrated and made concrete through numerous examples in settings that students will already have encountered.
To introduce basic principles of abstract algebraic structures and to teach how an extensive and important theory can be developed by logical deductions from a small number of axioms.
On completion of the course, students should:
• Know and understand the formal definitions for Groups, Rings, and Fields
• be able to produce simple proofs based on the algebraic axioms
• Be familiar with standard examples of these algebras, including the Symmetric Group, Modular Arithmetic, finite abelian groups, Polynomial and Matrix Rings, and examples of finite fields.
• Be familiar with the notions of subalgebras as they apply to Groups, Rings, and Fields
• Understand the notion of isomorphism and homomorphism of these algebra types
• (Level 7) have a comprehensive understanding and appreciation of the theory as above
• (Level 7) be able to produce more difficult arguments in proofs
• (Level 7) understand Euclidean domains, Principal Ideal Domains, and Unique Factorization Domains
• (Level 7) ED => PID => UFD theorem
Syllabus
Groups: Binary operations, groups, subgroups, cyclic groups, direct products, groups of permutations, cosets, Lagrange's theorem; Isomorphisms and homomorphisms of groups; Cayley graphs.
Rings, Fields, zero divisors and integral domains, subrings, ideals. Direct products, homomorphisms, Isomorphisms. The Ring of integers modulo n, polynomial rings.
Fields including simple examples of finite fields.
This module will run in alternate years (first year 2018/19).
Teaching will be delivered in a way that blends face-to-face classes, for those students that can be present on campus, with a range of online lectures, teaching, learning and collaborative support.
There will be additional sessions on Ring Theory (assessed in final examination).

Exam format definitions
- Remote, open book: Your exam will take place remotely via an online learning platform. You may refer to any physical or electronic materials during the exam.
- In-person, open book: Your exam will take place on campus under invigilation. You may refer to any physical materials such as paper study notes or a textbook during the exam. Electronic devices may not be used in the exam.
- In-person, open book (restricted): The exam will take place on campus under invigilation. You may refer only to specific physical materials such as a named textbook during the exam. Permitted materials will be specified by your department. Electronic devices may not be used in the exam.
- In-person, closed book: The exam will take place on campus under invigilation. You may not refer to any physical materials or electronic devices during the exam. There may be times when a paper dictionary,
for example, may be permitted in an otherwise closed book exam. Any exceptions will be specified by your department.
Your department will provide further guidance before your exams.

be necessary to make changes, for example to programmes, modules, facilities or fees. Examples of such reasons might include a change of law or regulatory requirements,
industrial action, lack of demand, departure of key personnel, change in government policy, or withdrawal/reduction of funding. Changes to modules may for example consist
of variations to the content and method of delivery or assessment of modules and other services, to discontinue modules and other services and to merge or combine modules.
The University will endeavour to keep such changes to a minimum, and will also keep students informed appropriately by updating our programme specifications and module directory.
