Type of module:

Summary module description:
Operator theory is a diverse area that has grown out of linear algebra and complex analysis, and is often described as the branch of functional analysis that deals with bounded linear operators and their (spectral) properties. It has developed with strong links to (mathematical) physics and mechanics, and continues to attract both pure and applied mathematicians in its vast area.

Aims:

To introduce the basic theory of Banach algebras and spectral theory, to develop further theory of bounded operators on Hilbert space, to discuss the theory of compact and Fredholm operators, and finally apply the results to the study ofÌýinfinite matrices and concrete operators in function spaces.

Assessable learning outcomes:

By the end of the module students are expected to be able to:

• use Banach algebra techniques to solve problems in mathematics, applied mathematics and mathematical physics;


• demonstrate understanding of the difference between Banach space and Hilbert space operators;


• demonstrate understanding of the geometry of Hilbert space;


• solve problems involving bounded linear operators acting on function spaces





This module will be assessed to a greater depth than the excluded module MA3OT.Ìý

Additional outcomes:
To understand the fruitful interplay between functional analysis, complex analysis and linear algebra, and how this produces remarkable results in mathematics and its applications.

Outline content:
Banach algebras. Basic geometry of Hilbert space. Introduction to the theory of C*-algebras. Further theory of compact and bounded linear operators on Hilbert space. Fredholm operators. Concrete operators (such as Toeplitz and Hankel operators) acting on function spaces (such as Hardy and Bergman spaces).

Penalties for late submission:

The Support Centres will apply the following penalties for work submitted late:

• where the piece of work is submitted after the original deadline (or any formally agreed extension to the deadline): 10% of the total marks available for that 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.

Assessment requirements for a pass:
A mark of 50% overall.

Reassessment arrangements:

One examination paper of 2 hours duration in August/September.
