RIEMANNIAN GEOMETRY - 2021/2
Module code: MAT3044
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.
The module introduces the subject of manifolds of dimension greater than two, with particular emphasis on manifolds which admit a metric which enables the measurement of distance. The course begins with the introduction of manifolds and metrics, with illustrative examples such as spheres, hyperbolic spaces, and Lie groups. The course continues with geodesics, isometries, covariant derivatives, the Levi Civita connection, and concludes with curvature and its properties.

|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 geometry of various surfaces in higher dimensional space.
- A knowledge of the subject, important definitions, and concepts.
- 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 four 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 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 the geometry of manifolds of dimension greater than two, with the added feature of a metric on the manifold.
- Introduce the students to the concepts of a covariant derivative and connection and their implications.
- Analysis of the above new concepts in the setting of examples like hypersurfaces, homogeneous spaces, and projective spaces.
|1||On successful completion of this module, students should understand the fundamental properties of Riemannian geometry, including the concept of a manifold, the use of a metric, the definition of a covariant derivative and its relation to a connection, the fundamental theory of Riemannian geometry, isometries, geodesics, parallel transport, and the various curvatures of a Riemannian manifold.||KC|
|2||On successful completion of the module the students should have a clear idea of how to implement the above theory in examples.||KCP|
C - Cognitive/analytical
K - Subject knowledge

Overall student workload
Independent Study Hours: 117
Lecture Hours: 33
Methods of Teaching / Learning
The learning and teaching strategy is designed to:
Be an introduction to the core ideas in Riemannian geometry, concentrating in particular on metric, covariant derivative, and curvature and how they can be used to identify properties and 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 dedicated lectures for example classes to discuss aspects of the examples and their solution.
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.
