Seminar at FU Berlin, Winter Term 2015-2016

Lei Zhang

Introduction

In this seminar we are going to discuss the applications of analytic methods to number theory. The first aim the seminar is to prove Dirichlet's theorem on arithmetic progressions which states that: given any two positive coprime integers \(a\), \(m\), the set of numbers \(\{a, a+m, a+2m, a+3m,\cdots \}\) contains infinitely many prime numbers. The proof resorts to Dirichlet series, Riemann Zeta functions, Dirichlet \(L\)-function which are very basic tools in the study of analytic number theory. Then we are going to study Modular Forms. Modular forms are holomorphic functions on the upper half plan satisfying certain conditions with respect to some group actions. It is another very important tool to number theory.

Prerequisites

The prerequests for this seminar are rather few. A certain familiarity with undergraduate level real and complex analysis is enough.
