MATH 7230 - Spring 2018

Analytic Number Theory

This course is an introduction to analytic number theory, the goal of which is to determine precise estimates for arithmetic functions and primes. We will cover classical and modern results, with a particular focus on recent advances in sieve methods (with applications to prime gaps). See the Syllabus and detailed Lecture Schedule for more details.
