A simple approach to the summation of certain slowly convergent series. (English) Zbl 0808.40001

Summary: Summation of series of the form \(\sum^ \infty_{k = 1} k^{\nu-1} r(k)\) is considered, where \(0 \leq \nu \leq 1\) and \(r\) is a rational function. By an application of the Euler-Maclaurin summation formula, the problem is reduced to the evaluation of Gauss’ hypergeometric function. Examples are given.
