Pochhammer symbol with negative indices. A new rule for the method of brackets

open access: yesOpen Mathematics, 2016
The method of brackets is a method of integration based upon a small number of heuristic rules. Some of these have been made rigorous. An example of an integral involving the Bessel function is used to motivate a new evaluation rule.

Integral transforms involving a generalized k-Bessel function

open access: yesDemonstratio Mathematica, 2023
The main goal of this study was to look into some new integral transformations that are associated with a generalized kk-Bessel function. Integral formulas for the generalized kk-Bessel function have been established using the Laplace transform, Euler ...

On some geometric results for generalized k-Bessel functions

open access: yesDemonstratio Mathematica, 2023
The main aim of this article is to present some novel geometric properties for three distinct normalizations of the generalized kk-Bessel functions, such as the radii of uniform convexity and of α\alpha -convexity.

An extension of the method of brackets. Part 2

open access: yesOpen Mathematics, 2020
The method of brackets, developed in the context of evaluation of integrals coming from Feynman diagrams, is a procedure to evaluate definite integrals over the half-line. This method consists of a small number of operational rules devoted to convert the

Accurate analytic approximations to eigenvalues anharmonic potentials x2+λx8

open access: yesResults in Physics, 2020
Precise analytic approximations have been found for the eigenvalues of the ground state in the anharmonic potentials x2+λx8. Rational functions combined with fractional powers are used to determine the new approximations.

Turán-Type Inequalities for Bessel, Modified Bessel and Kr ̈tzel Functions

open access: yesJournal of Kufa for Mathematics and Computer, 2018
We establish Turán-type inequalities for Bessel functions, modified Bessel functions, Kr ̈tzel function and Beta function, by using a new form of Cauchy–Bunyakovsky–Schwarz inequality.

Asymptotics of a ${}_3F_2$ polynomial associated with the Catalan-Larcombe-French sequence [PDF]

open access: yes, 2006
The large $n$ behaviour of the hypergeometric polynomial $$\FFF{-n}{\sfrac12}{\sfrac12}{\sfrac12-n}{\sfrac12-n}{-1}$$ is considered by using integral representations of this polynomial.

Generating relations of multi-variable Tricomi functions of two indices using Lie algebra representation

open access: yesArab Journal of Mathematical Sciences, 2014
This paper is an attempt to stress the usefulness of the multi-variable special functions. In this paper, we derive certain generating relations involving 2-indices 5-variables 5-parameters Tricomi functions (2I5V5PTF) by using a Lie-algebraic method ...

Precise analytic approximations for the Bessel function J1(x)

open access: yesResults in Physics, 2018
Precise and straightforward analytic approximations for the Bessel function J1(x) have been found. Power series and asymptotic expansions have been used to determine the parameters of the approximation, which is as a bridge between both expansions, and ...
