We study analytic properties of spectral zeta functions associated to actions of the quantum group SUq(2) such as Z(s, SUq(2)), the zeta function corresponding to the regular representation introduced in [15]. As an application, we show the special value ζ(3) of the Riemann zeta function ζ(s) is given in terms of the classical limit of Z(s, SUq(2)). We further discuss a spectral zeta function
associated with the so-called model of the representations of
and show a presence of its series of "trivial" zeros, which is noteworthy.
