Integrable Systems and Mathematical Physics

Integrable systems is a branch of mathematics which first came to prominence in the mid 1960's with the (mathematical) discovery of the soliton by Kruskal and Zabusky while studying dispersive shallow water waves. Broadly speaking the focus is on systems for which - despite their nonlinear behaviour - exact solutions can be derived. Today the field has come to embrace many different aspects of mathematical physics and is at the cross-roads with other modern branches of pure and applied mathematics.

Our group is one of the largest in the UK, is part of an LMS network on quantum and classical integrability and hosts its own series of international conferences, ISLAND. Staff members have a diverse range of interests including topics in algebra and geometry; details of these are given below. We welcome applications by prospective PhD students; please click on "Postgraduate Opportunities" below for examples of possible projects.

    (classical and quantum, finite and affine) W-algebras (PhD)

    Supervisors: Daniele Valeri
    Relevant research groups: Integrable Systems and Mathematical Physics

    A novel approach to W-algebras using Lax operators has been recently developed. This approach nicely shows the deep relation between W-algebras, integrable systems and Yangians. Further investigations of these relations deserves to be studied. In particular, the Lax type operator approach should be extended to quantum affine W-algebras and used to understand better their representations and relations with quantum integrable systems.
