Summary module description:

This module is an introduction to the basic concepts of algebra, centered around group, ring and field theory.

Aims:

To develop the basic theory of groups, rings and fields; to illustrate the fascinating and unexpected interconnections among seemingly unrelated topics, especially between concrete and "abstract" algebra.

Assessable learning outcomes:

By the end of the module students are expected to be able to:

• Work with groups, subgroups and quotient groups;

• Recognise homomorphisms and establish simple isomorphisms;

• Work with permutations expressed in cycle notation;

• Recognise subrings and ideals;

• Construct quotient rings;

• Construct simple algebraic extensions.

By the end of the course, students are expected to have acquired skill in logical reasoning and construction of proofs.

Outline content:

The first half of the module studies in detail the basic theory of groups, i.e. sets equipped with an abstract operation of multiplication satisfying certain axioms modelled on a plethora of motivating examples. This provides both an understanding of the common properties of many different kinds of mathematical objects and insight into the differences between them. In particular the following topics will be  discussed:

• Groups, subgoups, quotient groups, L agrange's Theorem, cyclic groups, symmetric groups, homomorphisms and isomorphisms, Cayley's Theorem.

• The second part of the module proceeds along the same pattern to introduce the theory of rings and fields. In particular the following topics will be discussed:

• Rings, subrings, ideals, the quotient ring with respect to an ideal, ring homomorphisms, polynomials and polynomial rings, algebraic and transcendental extensions, finite fields.

Penalties for late submission:

The Support Centres will apply the following penalties for work submitted late:

• where the piece of work is submitted after the original deadline (or any formally agreed extension to the deadline): 10% of the total marks available for that piece of work will be deducted from the mark for each working day (or part thereof) following the deadline up to a total of five working days;
• where the piece of work is submitted more than five working days after the original deadline (or any formally agreed extension to the deadline): a mark of zero will be recorded.
The University policy statement on penalties for late submission can be found at: http://www.reading.ac.uk/web/FILES/qualitysupport/penaltiesforlatesubmission.pdf
You are strongly advised to ensure that coursework is submitted by the relevant deadline. You should note that it is advisable to submit work in an unfinished state rather than to fail to submit any work.

Assessment requirements for a pass:

A mark of 40% overall.

Reassessment arrangements:

One examination paper of 3 hours duration in August/September - the resit module mark will be the higher of the exam mark (100% exam) and the exam mark plus previous coursework marks (80% exam, 20% coursework).
