New Harmonic Number Series [PDF]

open access: yesAppliedMath
Based on a recent representation of the psi function due to Guillera and Sondow and independently Boyadzhiev, new closed forms for various series involving harmonic numbers and inverse factorials are derived.

Polynomials Related to Harmonic Numbers and Evaluation of Harmonic Number Series I [PDF]

open access: yesApplicable Analysis and Discrete Mathematics, 2010
In this paper we focus on two new families of polynomials which are connected with exponential polynomials and geometric polynomials. We discuss their generalizations and show that these new families of polynomials and their generalizations are useful to

Harmonic sets and the harmonic prime number theorem [PDF]

open access: yesBulletin of the Australian Mathematical Society, 2005
We restrict primes and prime powers to sets H(x)= U∞n=1 (x/2n, x/(2n-1)). Let θH(x)= ∑ pεH(x)log p. Then the error in θH(x) has, unconditionally, the expected order of magnitude θH (x)= xlog2 + O(√x). However, if ψH(x)= ∑pmε H(x) log p then ψH(x)= xlog2+

Harmonic number identities via polynomials with r-Lah coefficients

open access: yesComptes Rendus. Mathématique, 2020
In this paper, polynomials whose coefficients involve $r$-Lah numbers are used to evaluate several summation formulae involving binomial coefficients, Stirling numbers, harmonic or hyperharmonic numbers.

Series of Convergence Rate −1/4 Containing Harmonic Numbers

open access: yesAxioms, 2023
Two general transformations for hypergeometric series are examined by means of the coefficient extraction method. Several interesting closed formulae are shown for infinite series containing harmonic numbers and binomial/multinomial coefficients.

Unitary Harmonic Numbers [PDF]

open access: yesProceedings of the American Mathematical Society, 1975
If d ∗ ( n ) {d^ \ast }(n) and σ ∗ ( n ) {\sigma ^ \ast }(n) denote the number and sum, respectively, of the unitary divisors of the natural number n n

Dedekind harmonic numbers

open access: yesProceedings - Mathematical Sciences, 2021
The harmonic sums \(\sum_{r=k+1}^n \frac{1}{r}\) are not integers for any \(k \geq 1\). One way of proving this uses the Bertrand postulate that there is always a prime strictly between \(k\) and \(2k\) if \(k \geq 2\). The paper under review considers the more general analogous sums \(h_K(n) := \sum_{r=1}^n \frac{a_r}{r}\) where \(a_r\) is the number ...

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.

A note on harmonic number identities, Stirling series and multiple zeta values [PDF]

open access: yesInternational Journal of Number Theory, 2018
We study a general type of series and relate special cases of it to Stirling series, infinite series discussed by Choi and Hoffman, and also to special values of the Arakawa–Kaneko zeta function, studied before amongst others by Candelpergher and Coppo ...
