MATH40710 Galois Theory

Academic Year 2023/2024

This is a standard course on field and Galois theory, a cornerstone of advanced algebra. It is the culmination of undergraduate mathematics in algebra, using the theory of groups, rings, modules, and fields in a beautiful way to solve central problems of both ancient and modern mathematics.
