Web2. Some basic zeta functions In this section we will construct analytical continuations of basic zeta func-tions. From these we will determine the meromorphic structure, residues at singular points and special function values. 2.1. Hurwitz zeta function. We start by considering a generalization of the Riemann zeta function R.s/D X1 nD1 1 ns: (2-1) In mathematics, the Hurwitz zeta function is one of the many zeta functions. It is formally defined for complex variables s with Re(s) > 1 and a ≠ 0, −1, −2, … by $${\displaystyle \zeta (s,a)=\sum _{n=0}^{\infty }{\frac {1}{(n+a)^{s}}}.}$$This series is absolutely convergent for the given values of s and a and … Meer weergeven The Hurwitz zeta function satisfies an identity which generalizes the functional equation of the Riemann zeta function: valid for Re(s) > 1 and 0 < a ≤ 1. The Riemann … Meer weergeven Closely related to the functional equation are the following finite sums, some of which may be evaluated in a closed form Meer weergeven The partial derivative of the zeta in the second argument is a shift: Thus, the Meer weergeven The discrete Fourier transform of the Hurwitz zeta function with respect to the order s is the Legendre chi function. Meer weergeven A convergent Newton series representation defined for (real) a > 0 and any complex s ≠ 1 was given by Helmut Hasse in 1930: $${\displaystyle \zeta (s,a)={\frac {1}{s-1}}\sum _{n=0}^{\infty }{\frac {1}{n+1}}\sum _{k=0}^{n}(-1)^{k}{n \choose k}(a+k)^{1-s}.}$$ Meer weergeven The Laurent series expansion can be used to define generalized Stieltjes constants that occur in the series $${\displaystyle \zeta (s,a)={\frac {1}{s-1}}+\sum _{n=0}^{\infty }{\frac {(-1)^{n}}{n!}}\gamma _{n}(a)(s-1)^{n}.}$$ In particular, … Meer weergeven Negative integers The values of ζ(s, a) at s = 0, −1, −2, ... are related to the Bernoulli polynomials: $${\displaystyle \zeta (-n,a)=-{\frac {B_{n+1}(a)}{n+1}}.}$$ For … Meer weergeven
