Research
Anthony is a member of the Department of Applied Mathematics and Theoretical Physics and works in the Applied and Computational Analysis group. His research interests include: novel approaches to elliptic boundary value problems, Lie groups in PDE, new approaches to rigorous problems in Linear PDE theory and certain aspects of mathematical physics.
Teaching
I am lecturing the Part III course Distribution Theory & Applications, which focuses on classical distribution theory and application to the analysis of linear PDEs. Example sheets are here and the corresponding solutions will appear below
There are also some handouts
I've also lectured Part II Integrable Systems which includes topics such as: the Arnold-Liouville theorem, inverse scattering, infinite dimensional Hamiltonian systems and Lie group methods in PDE. Handouts were
- Generating functions
- Arnold-Liouville theorem and worked example
- Evolution of scattering data
- From Lax pairs to zero curvature
- Painlevé equations
In Lent term 2019 I am lecturing Part IA Vector Calculus, where we take a look extending our ideas about calculus to two and three dimensions. We go on to discuss some aspects of PDE and right towards the end we start to look at Cartesian tensors. Handouts are
I will update this set of notes as we progress through the course. They currently cover lectures 1-9.
