Geometry and Topology

  • A deformation of a singularity

    Singularity

    The study of such objects brings together ring theory, topology and algebraic geometry and has applications in integrable systems and mathematical physics.

  • A braid

    Braid

    Braids appear spontaneously in both topology and category theory, for reasons that turn out to reveal deep connections between these subjects.

Research activity in Geometry and Topology occurs in several areas, including that of Category Theory.

Our interests in Geometry cover a broad range of topics including: algebraic geometry; differential geometry; geometric group theory; and interactions with differential equations, representation theory and string theory.

Our interests in Topology encompass low-dimensional topology and algebraic topology. While the study of these subjects often involves geometric intuition, Topologists tend to study much less `rigid' geometric situations than Geometers.

Category theory looks at mathematics on a large scale. The aim is to strip away inessential details in order to get to the essence of things.
