For integerp, |p|>1, and generic rationalxandz, we establish the irrationality of the series $$\begin{aligned} \ell _p(x,z)=x\sum _{n=1}^\infty \frac{z^n}{p^n-x}. \end{aligned}$$It is a symmetric () generalization of theq-logarithmic function (andwhere), which in turn generalizes theq-harmonic series (). Our proof makes use of the Hankel determinants built on the Padé approximations to.
