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

open access: diamondJournal 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.

Monotonicity and complete monotonicity of some functions involving the modified Bessel functions of the second kind [PDF]

open access: diamondComptes Rendus. Mathématique, 2023
In this paper, we introduce some monotonicity rules for the ratio of integrals. Furthermore, we demonstrate that the function $-T_{\nu ,\alpha ,\beta }(s)$ is completely monotonic in $s$ and absolutely monotonic in $\nu $ if and only if $\beta \ge 1 ...

On Kudriasov Conditions for Univalence of Integral Operators Defined by Generalized Bessel Functions

open access: yesMathematics, 2022
In this article, we studied the necessary conditions for the univalence of integral operators that involve two functions: the generalized Bessel function and a function from the well-known class of normalized analytic functions in the open unit disk. The

The Spherical Harmonic Family of Beampatterns

open access: yesAcoustics, 2022
The free space solution to the wave equation in spherical coordinates is well known as a separable product of functions. Re-examination of these functions, particularly the sums of spherical Bessel and harmonic functions, reveals behaviors which can ...

Relation of Some Known Functions in terms of Generalized Meijer G-Functions

open access: yesJournal of Mathematics, 2021
The aim of this paper is to prove some identities in the form of generalized Meijer G-function. We prove the relation of some known functions such as exponential functions, sine and cosine functions, product of exponential and trigonometric functions ...

Arithmetic Means for a Class of Functions and the Modified Bessel Functions of the First Kind

open access: yesMathematics, 2019
In the paper, by virtue of the residue theorem in the theory of complex functions, the authors establish several identities between arithmetic means for a class of functions and the modified Bessel functions of the first kind, present several identities ...

Explicit solutions to fractional diffusion equations via Generalized Gamma Convolution [PDF]

open access: yes, 2010
In this paper we deal with Mellin convolution of generalized Gamma densities which leads to integrals of modified Bessel functions of the second kind. Such convolutions allow us to explicitly write the solutions of the time-fractional diffusion equations

Redheffer type inequalities for modified Bessel functions

open access: yesArab Journal of Mathematical Sciences, 2016
In this short note, we give new proofs of Redheffer’s inequality for modified Bessel functions of first kind published by Ling Zhu (2011). In addition, using the Grosswald formula we prove new Redheffer type inequality for the modified Bessel functions ...
