Query: On some series formed by values of the Riemann Zeta function   The partial fraction expansion of coth($\pi$z), due to Euler, is generalized
to power series having for coefficients the Riemann zeta function evaluated at
certain arithmetic sequences. A further generalization using arbitrary
Dirichlet series is also proposed. The resulting formulas are new, as far as we
know, since they could not be found in any of the classical or recent handbooks
of formulas that were at our disposal.
