Analytic methods

Definition

Analytic methods refer to techniques used in mathematics that involve the use of analysis, such as calculus, to derive results about numbers and their properties. These methods are particularly useful in understanding the distribution of prime numbers, as well as in computing class numbers, which are fundamental in algebraic number theory for determining how ideal classes behave in number fields.
