Semester 1: The highlight of this Group Theory module is Sylow's Theorem, which is probably the most fundamental result about the structure of finite groups. The Jordan - Holder Theorem shows that simple groups are the building blocks from which other groups are built, while alternating groups are also provided as the first examples of non-abelian simple groups.
Semester 2: Galois theory studies field extensions, particularly those arising from adjoining roots of polynomials. To each field extension we associate the Galois group. The structure of the group is related to the structure of the field extension via the Fundamental Theorem of Galois Theory.
