Abstract:
We study a -logarithm which was introduced by Euler and give some of its properties. This -logarithm has not received much attention in the recent literature. We derive basic properties, some of which were already given by Euler in a 1751 paper and in a 1734 letter to Daniel Bernoulli. The corresponding -analogue of the dilogarithm is introduced. The relation to the values at and of a -analogue of the zeta function is given. We briefly describe some other -logarithms that have appeared in the recent literature.
