Summary  NB. This course is delivered *biennially* with the next instance being in 2023  24. It is anticipated that it would then be delivered every other session thereafter.
This course will cover the foundations of functional analysis in the context of normed linear spaces The Big Theorems (HahnBanach, Baire Category, Uniform Boundedness, Open Mapping and Closed Graph) will be presented and several applications will be analysed. The important notion of duality will be developed in Banach and Hilbert spaces and an introduction to spectral theory for compact operators will be given.

Course description 
This course covers major theorems of Functional Analysis that have applications in Harmonic and Fourier Analysis, Ordinary and Partial Differential Equations. This course is a natural follow on of the course Linear Analysis; while the main focus of the Linear Analysis is on Hilbert spaces with its rich geometrical structures this course will work with normed linear spaces. Hilbert space is a special case of a normed linear space. Despite working in this more general framework many results encountered in Linear Algebra will be reintroduced in this course in more general form. For example the spectral theorem will be presented for all compact operators.
Review of linear spaces and their norms.
The HahnBanach, Baire Category, Uniform Boundedness Principle, Open Mapping and Closed Graph theorems.
Duality in Banach and Hilbert spaces.
Spectral theory for compact operators on Banach spaces. Fredholm alternative.
Weak topologies, BanachAlaoglu and the ArzelaAscoli theorem.

Learning Outcomes
On completion of this course, the student will be able to:
 Demonstrate facility with the main, big theorems of functional analysis.
 Use duality in various contexts and theoretical results from the course in concrete situations.
