  Springer Online Reference Works   (Site not responding. Last check: 2007-10-17)
The function was subsequently studied by P.G.L. Dirichlet and also, with extraordinary success, by P.L. Chebyshev [2] in the context of the problem of the distribution of prime numbers.
Dedekind's zeta-function is the analogue of Riemann's zeta-function for algebraic number fields, and was introduced by R.

 Riemann zeta function - Encyclopedia, History, Geography and Biography
In mathematics, the Riemann zeta function, named after Bernhard Riemann, is a function of significant importance in number theory, because of its relation to the distribution of prime numbers.
It is this function that is the object of the Riemann hypothesis.
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.

The theory of L-functions should in the end contain the theory of zeta functions; an L-function is a potentially 'twisted' kind of zeta function.
The Selberg class S is an attempt to define zeta functions axiomatically, so that the properties of the class can be studied, and the members of the class classified.
The zeta functions should not be confused with the similar-sounding eta function.

dividing p of In complex analysis, a meromorphic function on an open subset D of the complex plane is a function that is holomorphic on all D except a set of isolated points, which are poles fore the function.
In complex analysis, a pole of a function is a certain type of simple singularity that behaves like the singularity of f(z) = 1/zn at z = 0; a pole of a function f is a point a such that f(z) approaches infinity as z approaches a.
Accordingly, the transition between the pseudo-Anosov and the periodic dynamic regime (in Thurston's terminology) in the case of gravity is being reinterpreted in terms of phase transitions in the Farey spin chain whose partition function is just a ratio of two Riemann zeta functions.

Finally, the Dedekind zeta function has a pole at s=1 and we need its residue (or, rather, the residue of zeta^ * (s)) which we compute using the class number formula.
The resulting L-function does not satisfy the required functional equation, so something unusual does happen at a prime where both E and K have bad reduction, which in this case must be either p=2 or p=3.

 [No title]
The \emph{Dedekind zeta function} $\zeta_K(s)$ is a function on the complex plane given, for $\Real(s) > 1$, by the absolutely convergent product and sum \[ \zeta_K(s) = \prod_\gothp (1 - \Norm(\gothp)^{-s})^{-1} = \zeta_K(s) = \sum_{\gotha} \Norm(\gotha)^{-s}, \] where in the sum $\gotha$ runs over the nonzero ideals of $\gotho_K$.
There is also a functional equation relating the values of $\zeta_K$ at $s$ and $1-s$, and an extended Riemann hypothesis: aside from ``trivial'' zeros along the negative real axis, the zeroes of $\zeta_K$ all have real part $1/2$.

Riemann viewed ζ(s) as a function in the complex variable s, and showed that it has an analytic continuation to C\{1}, with a simple pole with residue 1 at s=1.
