Number theory is one of the most ancient and fundamental branches of mathematics. Originally it was mainly occupied with finding natural solutions of algebraic equations. For example, solving the equation x^2+y^2=z^2 describes all right-angle triangles with integral side lengths. Nowadays, number theory is very diverse and relates to nearly all other areas: algebra and algebraic geometry, group representation theory, analysis, including complex and non-archimedean ones, dynamics and probability, model theory. Main directions represented in our group are: representation theory, modular forms, automorphic forms and L-functions, algebraic geometry, p-adic methods and non-archimedean methods.
