A -analogue of the Koecher-Leshchiner generating function of odd zeta values
Roberto Tauraso
In the 1980s, Koecher and, independently, Leshchiner found an elegant formula for the generating function of odd zeta values. In this short note, we derive a -analogue of this f…

Arithmetic properties of MacMahon-type sums of divisors: the odd case
James A. Sellers, Roberto Tauraso
A century ago, P. A. MacMahon introduced two families of generating functions, $$ \sum_{1\leq n_1<n_2<\cdots<n_t}\prod_{k=1}^t\frac{q^{n_k}}{(1-q^{n_k})^2} \quad\text{ and } \sum_{…

Congruences for sums involving
Sandro Mattarei, Roberto Tauraso
We primarily investigate congruences modulo for finite sums of the form over the ranges and , where is a prime larger than the p…
