Description
Module Overview: Functional Analysis
This module covers the following topics:
- Banach and Hilbert spaces
- Linear operators and linear functionals
- Fundamental theorems: Baire Category, Open Mapping, Uniform Boundedness Principle,...
- Weak and weak* topologies
- Operator topologies
- Convexity and the Krein-Milman Theorem
- The Banach-Stone Theorem
- The Markov-Kakutani Theorem
- General spectral theory: Banach algebras, Spectral theorem for self-adjoint operators
- Commutative C*-algebras – Gelfand’s theory
Weekly Preparation
Students should read and study the lecture notes prior to the lecture time and come prepared to discuss and ask questions about topics covered in the notes.
Assessment
This module is assessed in two take-home assignments with three questions per assignment:
Assignment 1
Released: Week 6
Due: Two weeks after release date
Assignment 2
Released: Week 10, last lecture
Due: Two weeks after release date
Assignments are weighted equally and each counts for 50% of the final grade.
