analytic number theory
One concept that is important in analytic number theory is asymptotic estimates. Tools that are used to obtain asymptotic estimates for sums include the Euler-Maclaurin summation formula (http://planetmath.org/EulerMaclaurinSummationFormula), Abel’s lemma (summation by parts), the convolution method, and the Dirichlet hyperbola method. Asymptotic estimates are important for determining asymptotic densities of certain subsets of the natural numbers.
Another one of Dirichlet’s contributions to analytic number theory is the Dirichlet series. As an example, the Dirichlet series of a Dirichlet character is a Dirichlet L-series. A tool that is helpful for studying any Dirichlet series is the Euler product. The most famous Dirichlet series is the Riemann zeta function, which is the Dirichlet series of the completely multiplicative function . This leads up to what is possibly the most important unsolved problem in analytic number theory: the Riemann hypothesis. This that all nontrivial zeros of the Riemann zeta function have real part equal to . Its to prime numbers is made clearer by the Euler product formula.
