## Overview

Symmetric functions are ubiquitous in many areas of mathematics. They arise naturally in group theory when studying the characters of the symmetric group and the general linear group. They also appear in the study of the geometry of grassmannians and flag varieties, and are an important tool in algebraic combinatorics and representation theory.

The main aim of the course will be to provide a solid introduction to the basics of symmetric polynomials and symmetric functions. After covering these basics, we will discuss applications of symmetric functions to other areas of mathematics. In particular, we will cover the following topics.

- Partitions and Young tableaux
- Symmetric polynomials and the ring of symmetric functions
- Elementary and complete homogeneous symmetric functions
- Power sum symmetric functions
- Schur functions and orthogonality
- Hopf algebra structure on the ring of symmetric functions
- Characters of the symmetric group
- Bosonic Fock space and the boson-fermion correspondence

## Prerequisites

Student should have completed introductory courses in group theory, and the theory of rings and modules. For example, students having completed uOttawa courses MAT 3143/3543 will have the required prerequisites. Completion of MAT 4141/5141 is an asset, but not a requirement.
