Number Theory, Algebra and Geometry
Number Theory, Algebra and Geometry
Research at Exeter in this group is mostly concerned with Number Theory, Algebra and Geometry. An important theme in modern mathematics is that number theory and geometry are closely interrelated, so that, for example, the function fields of algebraic curves behave in a very similar way to algebraic number fields.
Pure mathematics research at Exeter is spread between this group and Algebra and Dynamical Systems and Analysis. An important theme in modern mathematics is that number theory and geometry are closely interrelated, so that, for example, the function fields of algebraic curves behave in a very similar way to algebraic number fields. Arithmetic geometry combines and unifies the areas of Number Theory and Geometry. One often looks for invariants associated with objects of geometric and number-theoretic interest like curves or equations defined over an arithmetic field (a number field, a local field or a finite field). In many cases these invariants are elements in K-theory or in a (co)homology theory.
Particular areas of interest at Exeter include p-adic cohomology and the classification of p-divisible formal groups, fundamental groups of curves, lattices and codes, combinatorics and additive number theory, Galois module structure of rings of integers, analytic number theory, Iwasawa theory, Ergodic theory and applications in number theory and probability theory and Hopf-Galois structures on field extensions.
