Generalized Harmonic Numbers: Identities and Properties
Abstract
This paper builds on the research initiated by Boyadzhiev, but introduces generalized harmonic numbers, \[ Hn(α)= Σk=1n αkk, \] which enable the derivation of new identities as well as the reformulation of existing ones. We also generalize Gould's identity, allowing classical harmonic numbers to be replaced by their generalized counterparts. Our results contribute to a deeper understanding of the structural properties of these numbers and highlight the effectiveness of elementary techniques in uncovering new mathematical phenomena. In particular, we recover several known identities for generalized harmonic numbers and establish new ones, including identities involving generalized harmonic numbers together with Fibonacci numbers, Laguerre polynomials, and related sequences.
