Abstract

Purpose

The purpose of this paper is to develop a set of identities for Euler type sums of products of harmonic numbers and reciprocal binomial coefficients.

Method

We use analytical methods to obtain our results.

Results

We obtain identities for variant Euler sums of the type <a onClick="popup('http://www.iaumath.com/content/6/1/10/mathml/M1','MathML',630,470);return false;" target="_blank" href="http://www.iaumath.com/content/6/1/10/mathml/M1">View MathML</a>, and its finite counterpart, which generalize some results obtained by other authors.

Conclusions

Identities are successfully achieved for the sums under investigation. Some published results have been successfully generalized.
