Description including Unit Aims

Unit Aims

The unit aims to provide students with a firm grounding in the theory and techniques of functional analysis and to offer students ample opportunity to build on their problem-solving ability in this area.

Unit Description

This course sets out to explore some core notions in Functional Analysis. The focus of Functional Analysis is the study of infinite-dimensional vector spaces and the space of linear functions defined on an infinite-dimensional vector space. These spaces are endowed with some structures, e.g. norm, inner product, etc. Dealing with an infinite-dimensional space opens new possibilities, for example, Cauchy sequences may not converge. Banach spaces are spaces in which all Cauchy sequences converge. However, these spaces are in general very different from finite dimensional vector spaces. Hilbert spaces are an important subfamily of Banach spaces in which many of the familiar properties of finite-dimensional vector spaces hold.

Students will be introduced to the theory of Banach and Hilbert spaces. We reassert similar results to those studied in Linear Algebra in the finitedimensional setting. The highlight of the course will be an exposition of the four fundamental theorems in the Functional Analysis (Hahn-Banach theorem, uniform boundedness theorem, open mapping theorem, closed graph theorem). The unit may also include some discussion of the spectral theory of linear operators.

Functional analysis is helpful in the study of integral/differential equations and more general equations for operators in infinite dimensional spaces. It has found broad applicability in diverse areas of mathematics, physics, economics, and other sciences.

Relation to Other Units

This is a Level 7 version of the Level 6 unit Functional Analysis 3, and students may not take both units.

Intended Learning Outcomes

Learning objectives

By the end of the unit, students will

  • understand basic concepts and results in functional analysis;
  • be able to solve routine problems;
  • have developed skills in applying the techniques of the course to unseen situations.

Transferable skills

Deductive thinking; problem-solving; mathematical exposition

Teaching Information

The unit will be taught through a combination of

  • synchronous online and, if subsequently possible, face-to-face lectures
  • asynchronous online materials, including narrated presentations and worked examples
  • guided asynchronous independent activities such as problem sheets and/or other exercises
  • synchronous weekly group problem/example classes, workshops and/or tutorials
  • synchronous weekly group tutorials
  • synchronous weekly office hours

Assessment Information

  • 90% Timed, open-book examination
  • 10% Coursework


If this unit has a Resource List, you will normally find a link to it in the Blackboard area for the unit. Sometimes there will be a separate link for each weekly topic.

If you are unable to access a list through Blackboard, you can also find it via the Resource Lists homepage. Search for the list by the unit name or code (e.g. MATHM6202).

How much time the unit requires
Each credit equates to 10 hours of total student input. For example a 20 credit unit will take you 200 hours of study to complete. Your total learning time is made up of contact time, directed learning tasks, independent learning and assessment activity.

See the Faculty workload statement relating to this unit for more information.

The Board of Examiners will consider all cases where students have failed or not completed the assessments required for credit. The Board considers each student's outcomes across all the units which contribute to each year's programme of study. If you have self-certificated your absence from an assessment, you will normally be required to complete it the next time it runs (this is usually in the next assessment period).
The Board of Examiners will take into account any extenuating circumstances and operates within the Regulations and Code of Practice for Taught Programmes.
