  Riemann zeta function - LearnThis.Info Enclyclopedia   (Site not responding. Last check: 2007-11-03)
In mathematics, the Riemann zeta function is a function which is of paramount importance in number theory, because of its relation to the distribution of prime numbers.
Bernhard Riemann realized that the zeta function can be extended by analytic continuation in a unique way to a holomorphic function ζ(s) defined for all complex numbers s with s ≠ 1.
Although mathematicians regard the Riemann zeta function as being primarily relevant to the "purest" of mathematical disciplines, number theory, it also occurs in applied statistics (see Zipf's law and Zipf-Mandelbrot law), physics, and the mathematical theory of musical tuning.

 [No title]
While numerical computations on zeros of the Zeta function have long been focused on RH verification only (to check the RH, isolating the zeros is sufficient so no precise computations of the zeros are needed) it was Odlyzko who the first, computed precisely large consecutive sets of zeros to observe their distribution.
As referred by Odlyzko in [16] for example, this motivates the GUE hypothesis which is the conjecture that the distribution of the normalized spacing between zeros of the Zeta function is asymptotically equal to the distribution of the GUE eigenvalues.
It plays an important role in the study of the zeros of the Zeta function, because it was observed that special phenomenon about the zeta function on the critical line occurs when S(t) is large.

 Open Questions: The Riemann Hypothesis
Riemann (1826-66) studied the zeta function (including Euler, as we shall see), the notation is Riemann's, and hence the function is commonly known as the zeta function, after the greek letter ζ.

Carter decided to make a solid model of the zeta function for several reasons: the zeta function is an important mathematical question that is familiar to most mathematicians, and the zeta function, though rather complicated-looking, is sufficiently easy to form in three dimensions.
For the zeta function model, Carter and Bailey found that it was extremely difficult to clean the waste material from the narrow valleys.

 On the Characteristic Polynomial of a Random Unitary Matrix   (Site not responding. Last check: 2007-11-03)
The analogy between the characteristic polynomial of a random unitary matrix and Riemann's zeta function was first studied by Keating and Snaith in \cite{KS1}.
For example, they were able to conjecture the asymptotic form of the moments of the zeta function high up the critical line from a random matrix calculation.
These are then compared with the zeta function, and a conjecture for the left large deviations of $\log\zeta1/2+\i t$ is proposed.
