Programme/Approved Electives for 2020/21
Available as a Free Standing Elective
This module introduces and studies the abstract algebraic structure known as a group. Starting with the axiomatic and theoretical foundations, the module progresses, through a study of subgroups, to the proof of one of the most important theorems in Group Theory, Lagrange's Theorem. The module also examines applications of group theory, and the often beautiful way in which it interacts with geometry and number theory. It concludes with a preliminary exploration of other, closely related algebraic structures, namely rings and fields.This module provides develops material required for a large number of Level 6 options.
The module aims to provide students with their first rigorous treatment of group theory as an axiomatic system, as well as exploring applications to geometry and number theory. It also aims to expose students, at an introductory level, to other algebraic structures such as rings and fields.
