MSc Pure Mathematics

Fees for entry in 2027 have not yet been set. For reference, the fees for the academic year beginning September 2026 were as follows:

• MSc (full-time)
  UK students (per annum): £14,700
  International, including EU, students (per annum): £36,300
• MSc (part-time)
  UK students (per annum): £7,400
  International, including EU, students (per annum): £14,700

The fees quoted above are fully inclusive of tuition, administration and computational costs.

Fees for entry are subject to yearly review. The University reserves the right to increase your tuition fee by up to 7% each year for courses lasting more than one year, including to reflect rising costs associated with delivering our educational and wider student experience.

Always contact the admissions team if you are unsure which fee applies to your qualification award and method of attendance.

International student CAS deposit

Self-funded international applicants are required to pay a deposit of £2500 towards their tuition fees before a confirmation of acceptance for studies (CAS) is issued. Some applicants will be required to pay a higher deposit. More information on tuition fee deposits .

All students should normally be able to complete their programme of study without incurring additional study costs over and above the tuition fee for that programme. Any unavoidable additional compulsory costs totalling more than 1% of the annual home undergraduate fee per annum, regardless of whether the programme in question is undergraduate or postgraduate taught, will be made clear to you at the point of application. Further information can be found in the University's Policy on additional costs incurred by students on undergraduate and postgraduate taught programmes (PDF document, 91KB).

The Martingale Foundation helps provide access to postgraduate mathematics study for UK students facing financial barriers by offering fully-funded MSc and PhD programmes. Find more information on the Martingale Foundation website . Applications for 2027 scholarships open Wednesday 12 August 2026.

Our Manchester Master's Bursaries are aimed at widening access to master's courses by removing barriers to postgraduate education for students from underrepresented groups.

We also welcome the best and brightest international students each year and reward excellence with a number of merit-based scholarships. See our range of master’s scholarships for international students .

If you have completed or are in the final year of an undergraduate degree at The University of Manchester, you may be eligible for a discount of 10% on tuition fees for postgraduate study. Find out if you're eligible and how to apply .

In Mathematics it is often useful to study mathematical objects (such as groups, vector spaces, and topological spaces) not only in isolation, but also in relation to each other, by considering the appropriate kind of morphisms between them (such as group homomorphisms, linear maps and continuous functions, respectively). This apparently simple idea led to the discovery of one of the most important concepts of 21st century mathematics, that of a category, and the development of the corresponding theory, Category Theory.

Category Theory allows us to establish precise analogies between different parts of mathematics and to discover unexpected connections between them. This led to deep applications in Algebra, Algebraic Geometry, Algebraic Topology, and Logic. As such, Category Theory should be of interest to a wide range of students interested in Pure Mathematics.

In this unit, you will first learn about the basic notions and results of Category Theory, leading up to adjunctions and limits. You will then see some applications of Category Theory and explore how fundamental notions of Algebra and Logic can be phrased and studied category-theoretically. Throughout the unit, definitions and theorems will be illustrated with concrete examples.

Some knowledge of Logic is beneficial but not necessary.

MATH20201 Algebraic Structures 1 and one of MATH20212 Algebraic Structures 2 or MATH20122 Metric Spaces.  

Some knowledge of Logic is beneficial but not necessary. 

The unit aims to introduce the fundamental concepts, techniques, and results of Category Theory, and to illustrate how they can be applied to other parts of Mathematics, especially Algebra and Logic. 

• Define the notion of a category and check the axioms for it in simple examples.
   
• Define the notions of a functor and of a natural transformation and check the functoriality and naturality axioms in simple examples.
   
• Explain the equivalence between different formulations of the notion of an adjunction and apply them to identify adjunctions in simple examples.
   
• Name the fundamental kinds of limits and colimits and answer simple questions about their properties and relationship.
   
• Formulate and apply the fundamental result on preservation of limits by adjoint functors.
   
• Verify simple properties of syntactic categories.
   
• Relate precisely models of a theory and structure-preserving functors from its syntactic category.
   
• Relate precisely homomorphisms of models and natural transformations.

Feedback will be given on the weekly problem sheet assignments. Tutorials will provide an opportunity for students' work to be discussed and for feedback on their understanding to be given. Students can also get feedback on their understanding directly from the lecturer, for example during the lecturer's office hour.

Final exam - Generic feedback made available after exam period 100%
