Abstract

In this paper, we define generalized hyperharmonic numbers of order r, H-n,m(r) (sigma), for m is an element of Z(+) and give some applications by using generating functions of these numbers. For example, for n, r, s is an element of Z(+) such that 1 <= s <= r, Sigma(n)(k=1) [GRAPHICS] H-k,m(r-s) (sigma) = H-n,m(r) (sigma), and Sigma(n)(k=1) Sigma(k)(i=1) H-k-i,m(r+1) (sigma) D-r (k - i + r)/(n - k)! (k - i + r)! = H-n,m(2r+2) (sigma), where D-r (n) is an r-derangement number.
