Functional Analysis is an abstract theory that studies mathematical structures from a very general viewpoint. The theory it develops is of importance to topics from different branches of mathematics; for example: integral equations, dynamical systems, Optimisation Theory, and mathematical physics.
The most fundamental starting point is the generalisation of finite-dimensional vector spaces such as Rn to infinite-dimensional spaces such as spaces of sequences or functions. The corresponding generalisation of linear operators – i.e. the generalisation of matrices – then gives rise to a rich and fruitful theory.
The main focus of this module is on abstract theory, but examples will be given and a number of applications – e.g. to the theory of differential equations – will be considered as well.
Pre-requisite modules: ECM2701 Analysis, and either, ECM3740 or ECM3703
The objective of this module is to provide students with an introduction to Functional Analysis, and to cover a number of important theorems in mathematical analysis. A secondary goal is to increase the level of surety with which students can work in abstract settings such as function spaces. Examples and pointers to applications in other branches of mathematics are given to connect the abstract theory to concepts that students are familiar with from third- or second-year modules. Proofs will be carried out to further refine students' capabilities for axiomatic reasoning and mathematical rigour.
