Abstract

The generalized hyperharmonic numbers hn(m)(k)h_n^{(m)}(k) are defined by means of the multiple harmonic numbers. We show that the hyperharmonic numbers hn(m)(k)h_n^{(m)}(k) satisfy certain recurrence relation which allow us to write them in terms of classical harmonic numbers. Moreover, we prove that the Euler-type sums with hyperharmonic numbers: S(k,m;p):=n=1hn(m)(k)np    (pm+1, k=1,2,3)S\left( {k,m;p} \right): = \sum\limits_{n = 1}^\infty {\frac{{h_n^{\left( m \right)}\left( k \right)}}{{{n^p}}}} \;\;\left(p\geq m+1,\ {k = 1,2,3} \right) can be expressed as a rational linear combination of products of Riemann zeta values and harmonic numbers. This is an extension of the results of Dil (2015) \cite{AD2015} and Mezo¨\ddot{o} (2010) \cite{M2010}. Some interesting new consequences and illustrative examples are considered.
