# 18.785: Analytic Number Theory (MIT, Spring 2007)

Added 28 Oct 2015: an updated version of these notes will be kept here.

This is the web page for the course 18.785 (Analytic Number Theory), which was taught at MIT in the spring 2007 semester. This course was an introduction to analytic number theory, including the use of zeta functions and L-functions to prove distribution results concerning prime numbers (e.g., the prime number theorem in arithmetic progressions). The principal goal was to present the following theorem of Goldston, Pintz, and Yildirim (2005): if p_n denotes the n-th prime number, then

There is also a bit of discussion of non-abelian equidistribution results, like the Chebotarev density theorem, and the Sato-Tate conjecture for elliptic curves (and recent progress on same by Clozel, Harris, Shepherd-Barron, Taylor).

## Problem sets

The lecture notes I distribute in class and online will come with exercises attached; the problem sets will be extracted from these, as detailed below.
Problem sets are due in class on the indicated dates. However, I tend to be
pretty flexible about extensions in graduate courses, provided you ask
*in advance*. (You are free to ask not in advance, but at your own risk.)
