Mathematics (a) any member of several families of functions connected with elliptic integrals, typically denoted by ‘Z’ or ‘ζ’; (b) the Riemann zeta function; (in later use also) any of various functions generalizing the Riemann zeta function to a different context or otherwise regarded as somehow analogous to it.Frequently with modifying word.

If we know enough about the zeros of the zeta function, we can deduce a lot of new information about the primes from Riemann's formula. C2. zeta potential n.
