This course considers the classical topics in analytic number theory, with a focus on tools coming from Fourier analysis. The list of topics to be covered is as follows:

1. Review of the basic elements of Fourier analysis: Fourier transform in L^1 and L^2; Plancherel's theorem; Tempered distributions; Fourier series; Convolution and approximations of the identity.

2. Diophantine approximations; Equidistribution of sequences; Notions of discrepancy; Erdös-Turán inequality; Irregularities of distribution.

3. Arithmetic functions; The Riemann zeta-function; Dirichlet characters; Dirichlet L-functions; Gauss sums; Primes in arithmetic progression; Functional equation for L-functions; Zero-free regions for zeta and other L-functions; Prime Number Theorem.

4. Consequences of the Riemann hypothesis; Explicit formulas; Pair correlation of zeros; Prime gaps; Extremal functions and Fourier optimization methods.

5. Geometry of numbers; Minkowski's convex body theorem.
