Abstract
We obtain -analogues of several series for powers of . For example, the identity has the following -analogue: \begin{equation*} \sum_{k=0}^\infty(-1)^k\frac{q^{2k}(1+q^{2k+1})}{(1-q^{2k+1})^3}=\frac{(q^2;q^4)_{\infty}^2(q^4;q^4)_{\infty}^6} {(q;q^2)_{\infty}^4}, \end{equation*} where is any complex number with . We also give -analogues of four new series for powers of found by the second author.
