Brown has a strong and diverse group of number theorists and algebraic geometers whose work encompasses a wide variety of areas, including especially arithmetic geometry and analytic number theory. Arithmetic geometry is the study of number theoretic problems via a combination of techniques from algebraic number theory and differential and algebraic geometry; recent faculty research projects include Diophantine equations, elliptic curves, special values of zeta and L-functions, and motives, and motivic cohomology. Analytic number theory, especially the theory of modular and automorphic forms, is also a hot topic at Brown. In this subject, number theoretic quantities are encoded into analytic functions, and then methods from real and complex analysis and representation theory are used to analyze the functions and extract further number theoretic information. In addition to the regular faculty members whose main research interests are in the number theory or closely related fields, there are frequent visitors and a weekly number theory/algebraic geometry seminar as well as a graduate student seminar.
