Algebra and Number Theory Group
The Algebra and Number Theory Group at Queen Mary has a long and distinguished history, going back to such names as Kurt Hirsch, Karl Gruenberg and Ian G. Macdonald.

Having made its reputation primarily in group theory, the group now covers a range of areas in number theory, representation theory, automorphic forms, algebraic combinatorics, algebraic geometry, logic, homological/categorical algebra, and computational methods.
Research interests
- Structure of finite groups
- Growth functions on finitely-generated groups and their combinatorics and number-theoretic properties
- Computational group theory and group-theoretical databases
- Representations of finite groups
- Representations of p-adic groups
- Representations of symmetric groups and Hecke algebras
- Modular forms
- Maass forms
- Siegel modular forms
- Representations of p-adic groups
- Langlands programme
- L-functions
- Galois representations
- Arithmetic quantum chaos
- Algebraic graph theory
- Matroid theory
- Finite geometry
- Computation
- Combinatorics of partitions
- Topos theory
- Categorical logic
- Model theory of difference and differential fields
- Higher categorical/derived structures in algebra and geometry

- Combinatorial algebraic geometry
- Complex geometry
- Arithmetic geometry
- Non-Archimedean geometry
Group seminars
We normally hold our Algebra and Number Theory Seminar during term time. We aim for this seminar to be informal and accessible.
In conjunction with Imperial College, City University and Birkbeck University of London we also run the weekly London Algebra Colloquium, which has been running continuously since 1950.
