Generating Functions for Bessel Functions [PDF]

open access: yesCanadian Journal of Mathematics, 1959
On replacing the parameter n in Bessel's differential equation1.1by the operator y(∂/∂y), the partial differential equation Lu = 0 is constructed, where1.2This operator annuls u(x, y) = v(x)yn if, and only if, v(x) satisfies (1.1) and hence is a cylindrical function of order n.

A fourth-order Bessel fitting method for the numerical solution of the Schrödinger equation [PDF]

open access: yes, 1992
A new fourth-order method is developed for the numerical integration of the one-dimensional radial Schrödinger equation. This method integrates Bessel and Neumann functions exactly.

Appell-Type Functions and Chebyshev Polynomials

open access: yesMathematics, 2019
In a recent article we noted that the first and second kind Cebyshev polynomials can be used to separate the real from the imaginary part of the Appell polynomials. The purpose of this article is to show that the same classic polynomials can also be used

Phased Bessel functions [PDF]

open access: yes, 2008
In the study of photon-state transitions, we found a natural extension of the first kind of Bessel functions that extends both the range and domain of the Bessel functions from the real number field to the complex number field.

On the Zeros of the Big q-Bessel Functions and Applications

open access: yesMathematics, 2020
This paper deals with the study of the zeros of the big q-Bessel functions. In particular, we prove new orthogonality relations for functions which are similar to the one for the classical Bessel functions.

A new type of sharp bounds for ratios of modified Bessel functions [PDF]

open access: yes, 2016
The bounds for the ratios of first and second kind modified Bessel functions of consecutive orders are important quantities appearing in a large number of scientific applications.

Some results for Laplace-type integral operator in quantum calculus

open access: yesAdvances in Difference Equations, 2018
In the present article, we wish to discuss q-analogues of Laplace-type integrals on diverse types of q-special functions involving Fox’s Hq $H_{q}$-functions.

Error Bounds for the Large-Argument Asymptotic Expansions of the Hankel and Bessel Functions [PDF]

open access: yesActa Applicandae Mathematicae - An International Survey Journal on Applying Mathematics and Mathematical Applications, 2016
In this paper, we reconsider the large-argument asymptotic expansions of the Hankel, Bessel and modified Bessel functions and their derivatives. New integral representations for the remainder terms of these asymptotic expansions are found and used to ...

Laguerre-type Bessel functions [PDF]

open access: yes, 2005
In the framework of the 'monomiality principle', we introduce a class of Bessel-type functions which can be derived by applying the properties of an isomorphism, related to the so called Laguerre-type exponentials.

APPLICATION OF THE BESSEL-HYBRID FUNCTIONS FOR THE LINEAR FREDHOLM-VOLTERRA INTEGRO-DIFFERENTIAL EQUATIONS [PDF]

open access: yesRomanian Journal of Mathematics and Computer Science, 2015
In this paper a collocation method based on the Bessel-hybrid functions is used for approximation of the solution of linear Fredholm-Volterra integro-differential equations (FVIDEs) under mixed conditions.
