Course Description

This is a second course on Abstract Algebra. In this course, we will discuss more advanced topics in group theory and ring theory which include:

- Normal subgroups; quotient groups

- Free groups; presentations of groups

- Isomorphism theorems; subgroup series

- Group action; Cayley's theorem

- Sylow theorems and their applications

- Prime and maximal ideals

- Factorization in rings

- PIDs and UFDs

We assume as prerequisite a solid understanding of the basic theory of groups and rings, as covered in MATH2070/2078.
