To develop the student's understanding of groups, one of mathematics' most fundamental constructs.
Groups are one of the main building blocks in mathematics. They form the basis of all rings, fields and vector spaces, and many objects studied in analysis and topology have a group-theoretic structure. Also, physicists use groups to describe properties of the fundamental particles of matter. Pure mathematicians use them to study symmetry properties of geometric figures, in problems concerning permutations, to classify sets of objects like points of algebraic curves, and to study collections of matrices as well as in many other uses. The unit will cover the basic parts of the subject and study finite groups in some detail.
Relation to other units
This unit develops the Group Theory material in Level C/4 Pure Mathematics. The ideas are carried further in the Level M/7 units Representation Theory, Algebraic Topology, and Galois Theory.
After taking this unit, students should have gained an understanding of the basic properties of finite groups and an appreciation of the beauties of the subject and the limits of our present understanding.
