MAT-30013 - Group Theory

None

MAT-20025: Abstract Algebra

None

This module builds on the Group Theory introduced in MAT - 20025 to develop some of the mathematics underlying the classification of finite groups. This culminates in a proof of Sylow's First Theorem which offers a partial converse to Lagrange's Theorem proved in MAT - 20025. The module also develops some applications of Group Theory, the natural setting for which is that of group actions. Several examples of applying group theoretic ideas to counting combinatorial configurations are presented.

The aim of this module is to develop some of the mathematics underlying the classification of finite groups and to develop some applications of Group Theory.
