Algebra, logic and number theory
We are engaged in research across diverse and interrelated areas of algebra, logic and number theory.
We have concentrations of expertise across broad areas of fundamental pure research underpinning much of mathematics.
We explore algebra, model theory and number theory in depth as well as the connections between and with other disciplines such as geometry, dynamical systems and topology. We also have expertise in the emerging area of tropical mathematics, which has aspects of algebra and geometry.
Areas of expertise

Algebra
Algebra is the study of abstract objects arising from across mathematics, unifying apparently distant areas.

Logic
Logic studies formal languages and reasoning, often focusing on the interplay between axiomatic theories and their models.

Number theory
Number theory is an ancient area of mathematics involving the study of integers, wellknown for the simplicity of its statements and beauty of its proofs.

Semigroups and semirings
A semigroup is an algebraic structure with a single associative binary operation; if it has an identity element it is called a 'monoid'.
