Summary module description:
Functional analysis is a vast area of modern mathematics that in its simplest form studies infinite-dimensional linear (vector) spaces equipped with a given topology. The two main directions are the study of the geometry of the linear space and of the linear operators acting on the space. Our focus is on the former, while MA3/4OT (Operator Theory) is concerned with the latter. The types of linear spaces we study are Banach spaces and Hilbert spaces, which are the two most fundamental structures with great importance in other parts of mathematical analysis and its applications.
Aims:
To introduce the basic theory of Hilbert spaces, discuss their geometry, which generalizes the notion of the finite-dimensional Euclidean spaces, and demonstrate the effect of the dimension of the space in its study. To recall the concept of Banach spaces, introduced in MA3TLA, study their further properties, and provide examples of useful Banach spaces that are not Hilbert spaces. To discuss applications of functional analysis in other parts of mathematics and mathematical physics. To prepare students for further (MSc and Phd) studies in the area of analysis and its applications, and for a career in industry as a highly skilled research mathematician that can deal with a variety of (physical) applications.
Assessable learning outcomes:
By the end of the module students are expected to be able to:
• demonstrate understanding of the geometry of Hilbert spaces;
• demonstrate understanding of the difference between Hilbert and Banach spaces, and the role that the inner product of Hilbert space plays in it;
• prove the main theorems and use them to solve problems in other areas of mathematics.
Additional outcomes:
To understand the role that functional analysis plays in other branches of mathematics, mathematical physics and their applications.
Outline content:
Hilbert spaces, examples of Hilbert spaces, orthogonality, the Riesz representation theorem, orthonormal sets, isomorphic Hilbert spaces. Banach spaces, examples of Banach spaces, bounded linear operators and functionals, the Hahn-Banach theorem, the dual space, the open mapping theorem, the closed graph theorem, the principle of uniform boundedness. Applications.

Penalties for late submission:
The Module Convenor will apply the following penalties for work submitted late, in accordance with the University policy.
where the piece of work is submitted up to one calendar week after the original deadline (or any formally agreed extension to the deadline): 10% of the total marks available for the piece of work will be deducted from the mark for each working day (or part thereof) following the deadline up to a total of five working days;
where the piece of work is submitted more than five working days after the original deadline (or any formally agreed extension to the deadline): a mark of zero will be recorded.
The University policy statement on penalties for late submission can be found at:

You are strongly advised to ensure that coursework is submitted by the relevant deadline. You should note that it is advisable to submit work in an unfinished state rather than to fail to submit any work.
