Spectral geometry

Spectral geometry lies at the intersection of differential geometry, partial differential equations, and analysis. To a large extent it is motivated by questions originating in the study of real-life phenomena, such as vibration, heat propagation, oscillation of fluids, and quantum mechanical effects.<br /> <br /> For example a model question, posed by Mark Kac half a century ago is, Can one hear the shape of a drum? The challenge is to understand the geometry of an idealized drum from the set of its vibration frequencies, that is the Laplace eigenvalues. The question Kac poses is closely linked to other topics in spectral geometry, including shape optimization, spectral asymptotics, and spectral invariants.<br /> <br /> There are many starting points for a project in this general area, including isoperimetric inequalities, eigenvalue problems and spectral invariants in Riemannian geometry, eigenvalue problems in the minimal surface theory, and extremal eigenvalue problems.

Applicants to research degree programmes should normally have at least a first class or an upper second class British Bachelors Honours degree (or equivalent) in an appropriate discipline. The criteria for entry for some research degrees may be higher, for example, several faculties, also require a Masters degree. Applicants are advised to check with the relevant School prior to making an application. Applicants who are uncertain about the requirements for a particular research degree are advised to contact the School or Graduate School prior to making an application.

The minimum English language entry requirement for research postgraduate research study is an IELTS of 6.0 overall with at least 5.5 in each component (reading, writing, listening and speaking) or equivalent. The test must be dated within two years of the start date of the course in order to be valid. Some schools and faculties have a higher requirement.
