MANIFOLDS AND TOPOLOGY - 2021/2
Module code: MAT3009
In light of the Covid-19 pandemic, and in a departure from previous academic years and previously published information, the University has had to change the delivery (and in some cases the content) of its programmes, together with certain University services and facilities for the academic year 2020/21.
These changes include the implementation of a hybrid teaching approach during 2020/21. Detailed information on all changes is available at: https://www.surrey.ac.uk/coronavirus/course-changes. This webpage sets out information relating to general University changes, and will also direct you to consider additional specific information relating to your chosen programme.
Prior to registering online, you must read this general information and all relevant additional programme specific information. By completing online registration, you acknowledge that you have read such content, and accept all such changes.
This module introduces students to topological spaces and manifolds. Topology is the study of properties of spaces which are invariant under continuous transformations, and forms one of the cornerstones of pure mathematics. Study of topology leads to a deeper understanding of concepts of continuity and connectedness. After introducing these key ideas, with appropriate examples, smooth manifolds are introduced. Differential forms and cohomology are developed, which enables the classification of manifolds using topologically invariant numbers.

|Assessment type||Unit of assessment||Weighting|
|School-timetabled exam/test||IN-SEMESTER TEST (50 MINS)||20|
The assessment strategy is designed to provide students with the opportunity to demonstrate
- The ability to understand and formulate statements about the topology and geometry of various spaces.
- A knowledge of the subject, important definitions, and theorems with proofs
- The ability to apply this knowledge to the analysis of unseen problems in the tests and the examination.
Thus, the summative assessment for this module consists of:
One two hour examination (the best three answers out of five questions contribute to the exam mark) at the end of Semester 2; worth 80% of the module mark.
One in-semester test, worth 20% of the module mark.
Formative assessment and feedback
There is written feedback from marked coursework assignments over an 11 week period.
Verbal feedback is provided by the lecturer during seminars, and also in office hours.
- Introduce students to topological spaces, and ideas such as Haudsorff topological spaces, homeomorphisms, connectedness and compactness.
- Introduce students to the core ideas of differential geometry, such as smooth manifolds, vector fields, differential forms and operators such as the exterior derivative and the wedge product.
- Develop ideas of integration over manifolds, Stokes's Theorem and its applications, culminating in an investigation of de Rham cohomology, including the Poincarè Lemma and the Mayer-Vietoris sequence.
|1||Demonstrate understanding of topological spaces and smooth manifolds, properties of differential forms and the action of the exterior derivative and wedge product.||K|
|2||Apply these techniques in calculating the homotopy operator for closed differential forms, solving certain classes of partial differential equations, and using Stokes's Theorem to determine whether certain closed differential forms are exact.||KCT|
|3||Construct the Mayer-Vietoris sequence for large classes of manifolds and use the associated techniques to calculate the corresponding Betti numbers. Understand how this construction can be used to distinguish between topologically distinct spaces.||KC|
C - Cognitive/analytical
K - Subject knowledge
T - Transferable skills
P - Professional/Practical skills

Methods of Teaching / Learning
The learning and teaching strategy is designed to:
Be an introduction to the core ideas in topology and differential geometry, concentrating in particular on differential forms and how their properties can be used to classify different types of manifolds.
The learning and teaching methods include:
2x1 and 1x1 hour lectures per week, for 11 weeks, with typeset notes to complement the course, and Q+A opportunities for students.
4 additional seminars to discuss aspects of the course, such as the example
sheets provided to the students.
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
