Certain Mathematical Constants Associated with Harmonic Numbers and Higher-Dimensional Harmonic Sums

open access: yesMathematics
The Euler–Mascheroni constant γ, defined as the limiting difference between the harmonic numbers Hn and logn, has long been studied and appears in diverse areas of number theory, analysis, and special functions.

On Symplectically Harmonic Betti Numbers

open access: yesJournal of Geometry and Physics
Abstract Brylinski introduced the symplectic analogue of harmonic forms on symplectic manifolds, thereby defining the symplectically harmonic cohomology space of a symplectic manifold. In this paper, we derive a formula for determining the sym-plectically harmonic Betti numbers of an arbitrary symplectic manifold of finite type, based on the ...

Abel's Lemma and Identities on Harmonic Numbers

open access: yesIntegers, 2014
Recently, Chen, Hou and Jin used both Abel's lemma on summation by parts and Zeilberger's algorithm to generate recurrence relations for definite summations. Meanwhile, they proposed the Abel-Gosper method to evaluate some indefinite sums involving harmonic numbers.

Optimal Harmonic Period Assignment With Constrained Number of Distinct Period Values

open access: yesIEEE Access, 2020
Harmonic periods have been of great importance in the design of real-time applications due to their high schedulability, predictability, and ease of analysis.

Asymptotic inequalities for alternating harmonics [PDF]

open access: yesBulletin of Mathematical Sciences, 2019
For n ∈ ℕ the nth alternating harmonic number Hn∗ :=∑ k=1n(−1)k−1 1 k is given in the form Hn∗ =ln 2 + (−1)n+1 4⌊n+1 2 ⌋ +∑i=1q−1 (4i − 1)B 2i (2i)(2⌊n+1 2 ⌋)2i + rq(n), where q ∈ ℕ is a parameter controlling the magnitude of the error term rq ...

Many body effects in one-dimensional attractive Bose gases [PDF]

open access: yes, 2013
In this thesis we investigate the properties of ultra-cold quantum gases in reduced dimension and the effects of harmonic confinement on soliton-like properties.

Analysis of binning of normals for spherical harmonic cross-correlation [PDF]

open access: yes, 2012
Spherical harmonic cross-correlation is a robust registration technique that uses the normals of two overlapping point clouds to bring them into coarse rotational alignment.

Some extensions of Chu's formulas and further combinatorial identities [PDF]

open access: yesMathematica Bohemica
We present some extensions of Chu's formulas and several striking generalizations of some well-known combinatorial identities. As applications, some new identities on binomial sums, harmonic numbers, and the generalized harmonic numbers are also derived.
