Number Theory Research Group

Number theory is the study of all mathematics arising from the arithmetic of the ordinary integers. It is at once one of the most ancient disciplines, with integral Pythagorean triples appearing on ancient cuneiform tablets which are thousands of years old, and at the same time one of the most active and modern areas of study including the most famous problems of mathematics such as Fermat's Last Theorem, the Twin Primes Conjecture, the Riemann Hypothesis, and the grand system of conjectures known as the Langlands Program. Modern number theory is now also involved in vital applications through out society including digital communications and security systems.

    Number Theory, Automorphic Forms, and L-functions.

  • John Doyle

    B.S./M.A./Ph.D. University of Georgia, 2014.


    Dr. Doyle's main research interests are in the field of arithmetic dynamics, which is the study of dynamical systems from an algebraic perspective. His research involves techniques from number theory and algebraic geometry, and much of his work deals with moduli spaces which classify dynamical systems with prescribed dynamical behaviors.

    His primary interest is the study of the properties of algebraic number fields, in particular, those properties (discriminants, class-numbers, regulators) that can be studied with tools from the theory of algebraic matrix groups. This theory dates back to the work of Gauss on the theory of equivalence of binary integral quadratic forms. He also studies the theory of Riemann surfaces and Kleinian groups, a subfield of complex analysis. Surprisingly, many concepts in algebraic number theory have very precise analogues in the theory of surfaces. He is particularly interested in the properties of limit sets of Kleinian groups and in the shape of Teichmuller space, which is a kind of parameter space for Riemann surfaces.
