New series with Cauchy and Stirling numbers, Part 2

Khristo N. Boyadzhiev, Levent Kargın

Published 2021-03-17Version 1

We evaluate in closed form several series involving products of Cauchy numbers with other special numbers (harmonic, skew-harmonic, hyperharmonic, and central binomial). Similar results are obtained with series involving Stirling numbers of the first kind. We focus on several particular cases which give new closed forms for Euler sums of hyperharmonic numbers and products of hyperharmonic and harmonic numbers.
