A -analogue of Faulhaber's formula for sums of powers.
The aim of this paper is to give a q-analogue for complete monotonicity. We apply a classical characterization of Hausdorff moment sequences in terms of positive definiteness and complete monotonicity, adapted to the q-situation. The method due to Maserick and Szafraniec that does not need moments turns out to be useful. A definition of a q-moment sequence appears as a by-product.
The -derivative operator approach is illustrated by reviewing several typical summation formulae of terminating basic hypergeometric series.
