A complete monotonicity property of the multiple gamma function [PDF]

open access: yesComptes Rendus. Mathématique, 2020
We consider the following functions \[ f_n(x)=1-\ln x+\frac{\ln G_n(x+1)}{x} \text{ and }g_n(x)=\frac{\@root x \of {G_n(x+1)}}{x},\; x\in (0,\infty ),\; n\in \mathbb{N}, \] where $G_n(z)=\left(\Gamma _n(z)\right)^{(-1)^{n-1}}$ and $\Gamma _n$ is the ...

The multiple gamma function and its q-analogue [PDF]

open access: yesBanach Center Publications, 1996
We give an asymptotic expansion (the higher Stirling formula) and an infinite product representation (the Weierstrass product formula) of the Vign\'{e}ras multiple gamma function by considering the classical limit of the multiple q-gamma function.Comment:

FL-GRM:Gamma Regression Algorithm Based on Federated Learning [PDF]

open access: yesJisuanji kexue, 2022
People commonly hypothesize that an independent variable follows a Gamma distribution in many areas,including hydrology,meteorology and insurance claim.Under the Gamma distribution assumption,Gamma regression model enables an outstanding fitting effect ...

On criteria for algebraic independence of collections of functions satisfying algebraic difference relations [PDF]

open access: yesOpuscula Mathematica, 2017
This paper gives conditions for algebraic independence of a collection of functions satisfying a certain kind of algebraic difference relations. As applications, we show algebraic independence of two collections of special functions: (1) Vignéras ...

The Multiple Gamma-Functions and the Log-Gamma Integrals [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2012
In this paper, which is a companion paper to [W], starting from the Euler integral which appears in a generalization of Jensen’s formula, we shall give a closed form for the integral of log . This enables us to locate the genesis of two new functions and considered by Srivastava and Choi. We consider the closely related functionA(a)and the Hurwitz zeta

Inequalities Involving $q$-Analogue of Multiple Psi Functions

open access: yesComptes Rendus. Mathématique, 2020
Logarithmic derivative of the multiple gamma function is known as the multiple psi function. In this work $q$-analogue of multiple psi functions of order $n$ have been considered.

A Hardy–Hilbert-type integral inequality involving two multiple upper-limit functions

open access: yesJournal of Inequalities and Applications, 2023
By means of the weight functions, the idea of introducing parameters and the technique of real analysis, a new Hardy–Hilbert-type integral inequality with the homogeneous kernel 1 ( x + y ) λ ( λ > 0 ) $\frac{1}{(x + y)^{\lambda}}\ (\lambda > 0 ...

Jackson's integral of multiple Hurwitz–Lerch zeta functions and multiple gamma functions [PDF]

open access: yesJournal of Mathematical Analysis and Applications, 2018
Using the Jackson integral, we obtain the $q$-integral analogue of the Raabe type formulas for Barnes multiple Hurwitz-Lerch zeta functions and Barnes and Vardi's multiple gamma functions. Our results generalize $q$-integral analogue of the Raabe type formulas for the Hurwitz zeta functions and log gamma functions in [N. Kurokawa, K.

Abnormal Spontaneous Gamma Power Is Associated With Verbal Learning and Memory Dysfunction in Schizophrenia

open access: yesFrontiers in Psychiatry, 2020
BackgroundSchizophrenia patients exhibit cognitive deficits across multiple domains, including verbal memory, working memory, and executive function, which substantially contribute to psychosocial disability. Gamma oscillations are associated with a wide
