Logarithmically complete monotonicity of a function related to the Catalan-Qi function

open access: yesActa Universitatis Sapientiae: Mathematica, 2016
In the paper, the authors find necessary and sufficient conditions such that a function related to the Catalan-Qi function, which is an alternative generalization of the Catalan numbers, is logarithmically complete monotonic.

Construction a new generating function of Bernstein type polynomials [PDF]

open access: yesApplied Mathematics and Computation 218 (2011) 1072-1076, 2010
Main purpose of this paper is to reconstruct generating function of the Bernstein type polynomials. Some properties this generating functions are given. By applying this generating function, not only derivative of these polynomials but also recurrence relations of these polynomials are found.

A result regarding monotonicity of the Gamma function

open access: yesActa Universitatis Sapientiae: Mathematica, 2017
In this paper we analyze the monotony of the function ln Γ(x)ln (x2+τ)-ln (x+τ)${{{\rm{ln}}\,\Gamma ({\rm{x}})} \over {{\rm{ln}}\,({\rm{x}}^2 + \tau) - {\rm{ln}}\,({\rm{x}} + \tau)}}$ , for τ > 0.

Uniqueness of nontrivially complete monotonicity for a class of functions involving polygamma functions [PDF]

open access: yes, 2010
For $m,n\in\mathbb{N}$, let $f_{m,n}(x)=\bigr[\psi^{(m)}(x)\bigl]^2+\psi^{(n)}(x)$ on $(0,\infty)$. In the present paper, we prove using two methods that, among all $f_{m,n}(x)$ for $m,n\in\mathbb{N}$, only $f_{1,2}(x)$ is nontrivially completely ...

Two asymptotic expansions for gamma function developed by Windschitl’s formula

open access: yesOpen Mathematics, 2018
In this paper we develop Windschitl’s approximation formula for the gamma function by giving two asymptotic expansions using a little known power series.

On generalized fractional integral with multivariate Mittag-Leffler function and its applications

open access: yesAlexandria Engineering Journal, 2022
The fractional calculus (FC) has been extensively studied by researchers due to its vast applications in sciences in the last few years. In fractional calculus, multivariate Mittag–Leffler functions are considered the powerful extension of the classical ...

Umbral Methods and Harmonic Numbers

open access: yesAxioms, 2018
The theory of harmonic-based functions is discussed here within the framework of umbral operational methods. We derive a number of results based on elementary notions relying on the properties of Gaussian integrals.
