How do you find Hurwitz zeta function?

At rational arguments the Hurwitz zeta function may be expressed as a linear combination of Dirichlet L-functions and vice versa: The Hurwitz zeta function coincides with Riemann's zeta function ζ(s) when q = 1, when q = 1/2 it is equal to (2 s−1)ζ(s), and if q = n/k with k > 2, (n,k) > 1 and 0 < n < k, then.

How do you extend the zeta function to the whole plane?

The same equation in s above also holds when s is a complex number whose real part is greater than one, ensuring that the infinite sum still converges. The zeta function can then be extended to the whole of the complex plane by analytic continuation, except for a simple pole at s = 1.
The zeta function values listed below include function values at the negative even numbers ( s = −2, −4, etc. ), for which ζ(s) = 0 and which make up the so-called trivial zeros. The Riemann zeta function article includes a colour plot illustrating how the function varies over a continuous rectangular region of the complex plane.
Is the Riemann zeta function valid on the whole complex plane?
This is an equality of meromorphic functions valid on the whole complex plane. The equation relates values of the Riemann zeta function at the points s and 1 − s, in particular relating even positive integers with odd negative integers.

How do you prove Hurwitz's formula?
Hurwitz's formula has a variety of different proofs. One proof uses the contour integration representation along with the residue theorem. A second proof uses a theta function identity, or equivalently Poisson summation. These proofs are analogous to the two proofs of the functional equation for the Riemann zeta function in Riemann's 1859 paper.

What is Hurwitz's formula for Riemann zeta functional equation?

The Riemann zeta functional equation is the special case a = 1: (for Re ( s) < 0 and 0 < a ≤ 1). Hurwitz's formula has a variety of different proofs. One proof uses the contour integration representation along with the residue theorem. A second proof uses a theta function identity, or equivalently Poisson summation.
