Anthony is a member of the Department of Applied Mathematics and Theoretical Physics and works in the Applied and Computational Analysis group. He did his PhD under the supervision of Prof. A.S. Fokas. 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.
He is 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 are below.
There are also some handouts:
- Hand Out 1 (notation)
- Hand Out 2 (distributions supported at a point)
- Hand Out 3 (fundamental solution to heat operator)
He also lectures 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.
- Hand Out 1 (generating functions)
- Hand Out 2 (Arnold-Liouville worked example)
- Hand Out 3 (evolution of scattering data)
- Hand Out 4 (from Lax pairs to zero curvature)
- Hand Out 5 (Painleve transcendents)
