The London research grouping in geometry and number theory covers around 60 academics (faculty) and 30 postdocs. At the time of writing (October 2023) the LSGNT has four current student cohorts, with approximately 15 in each cohort. There are also many other research students working in these areas in London.
Our research covers very large areas of modern geometry and number theory. In geometry, we cover the spectrum from algebraic geometry, complex geometry, symplectic geometry, through to differential and riemannian geometry, geometric analysis, including techniques from nonlinear elliptic and parabolic partial differential equations. Subjects such as geometric group theory, knot theory, discrete systems and inverse problems are also represented.
Number theory is similarly broad, with researchers in both analytic and algebraic number theory, with specialists in (p-adic) Galois representations, modular and automorphic forms, arithmetic geometry, arithmetic aspects of spectral theory, arithmetic statistics and additive combinatorics.
Topics at the interface include the Langlands programme, arithmetic geometry, mirror symmetry, motives and moduli spaces.
Please browse to our academic staff pages for more detailed information.
