## Computing powers of two generalizations of the logarithm.(English)Zbl 1088.11015

Summary: We prove multiple-series representations for positive integer powers of the series $L(z;\alpha)=\sum_{n=1}^\infty\frac{z^n}{n+\alpha},\;\; |z|<1, \; \alpha\geq0, \quad\hbox{and}\quad \ell_q(z)=\sum_{n=1}^\infty\frac{z^nq^n}{1-q^n},\;\; |z|\leq1, \; |q|<1.$ The results generalize a known formula for powers of the series for the ordinary logarithm $$-\log(1-z) = L(z;0)$$.
