Infinitary harmonic numbers [PDF]

open access: yesBulletin of the Australian Mathematical Society, 1990
The infinitary divisors of a natural number n are the products of its divisors of the , where py is an exact prime-power divisor of n and (where yα = 0 or 1) is the binary representation of y. Infinitary harmonic numbers are those for which the infinitary divisors have integer harmonic mean.

Some identities of degenerate harmonic and degenerate hyperharmonic numbers arising from umbral calculus

open access: yesOpen Mathematics, 2023
Hyperharmonic numbers were introduced by Conway and Guy (The Book of Numbers, Copernicus, New York, 1996), whereas harmonic numbers have been studied since antiquity.

Median Bernoulli Numbers and Ramanujan’s Harmonic Number Expansion

open access: yesMathematics, 2022
Ramanujan-type harmonic number expansion was given by many authors. Some of the most well-known are: Hn∼γ+logn−∑k=1∞Bkk·nk, where Bk is the Bernoulli numbers.

Congruences for harmonic sums [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics, 2023
Zhao found a curious congruence modulo p on harmonic sums. Xia and Cai generalized his congruence to a supercongruence modulo p². In this paper, we improve the harmonic sums Hₚ(n)=Σ_{l₁+l₂+...+lₙ=p, l₁,l₂,...,lₙ>0} 1/l₁+l₂+...+lₙ to supercongruences ...

On q-generalized hyperharmonic numbers with two parameters [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
In this paper, we introduce q-generalized harmonic numbers with two parameters ω and ξ, H_{μ,λ,q}(ω,ξ) for integers μ, λ such that λ ≥ μ. With the help of these numbers, we define a new family of numbers which is called q-generalized hyperharmonic ...
