Bombieri norm

The Bombieri norm is a concept encountered in the study of number theory, particularly in the context of the distribution of prime numbers and analytic number theory. Named after mathematician Enrico Bombieri, the Bombieri norm is often defined in the context of bounding sums or integrals that involve characters or exponential sums, playing a role in various results related to prime number distributions, especially in the understanding of the Riemann zeta function and L-functions.
