Some Sums Involving Generalized Harmonic and r-Derangement Numbers

open access: yesCumhuriyet Science Journal
In this paper, we derive some sums involving generalized harmonic and r-derangement numbers by using generating functions of these numbers and some combinatorial identities. The relationship between Daehee numbers and generalized harmonic numbers of rank

How do populations aggregate?

open access: yesDemographic Research, 2021
Background: Understanding the relationship between populations at different scales plays an importantrole in many demographic analyses. Objective: We show that when a population can be partitioned into subgroups, the death rate forthe entire ...

Phi-Bonacci Butterfly Stroke Numbers to Assess Self-Similarity in Elite Swimmers

open access: yesMathematics, 2021
A harmonically self-similar temporal partition, which turns out to be subtly exhibited by elite swimmers at middle distance pace, is formally defined for one of the most technically advanced swimming strokes—the butterfly.

A Type of Mean Values of Several Positive Numbers with Two Parameters [PDF]

open access: yes, 2006
In this article, a type of mean values of several positive numbers with two parameters are defined by using the generalized Vandermonde determinant, some basic properties of them are given, and several inequalities for some mean values including the ...

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 ...

q-Analogs of Hn,mrσ and Their Applications

open access: yesMathematics, 2023
In this paper, inspired by recent works, we define q-analogs of Hn,mσ and Hn,mrσ. By implementing them, we obtain new interesting results by taking the derivative or using generating functions.

Ternary SU(3)-group symmetry and its possible applications in hadron-quark substructure. Towards a new spinor-fermion structure [PDF]

open access: yesEPJ Web of Conferences, 2019
The questions on the existence of the three color quark symmetry and three quark-lepton generations could have the origin associated with the new exotic symmetries outside the Cartan-Killing-Lie algebras/groups.
