A method for computing Bessel function integrals

, 1972
Infinite integrals involving Bessel functions are recast, by means of an Abel transform, in terms of Fourier integrals. As there are many efficient numerical methods for computing Fourier integrals, this leads to a convenient way of approximating Bessel ...

Accurate Analytical Approximation for the Bessel Function J₂(x)

Mathematical and Computational Applications
We obtain an accurate analytic approximation for the Bessel function J2(x) using an improved multipoint quasirational approximation technique (MPQA). This new approximation is valid for all real values of the variable x, with a maximum absolute error of ...

Received Probability of Vortex Modes Carried by Localized Wave of Bessel–Gaussian Amplitude Envelope in Turbulent Seawater

Journal of Marine Science and Engineering, 2019
By using the two-frequency coherence function model of a beam in a turbulent medium and the localized wave theory of the polychromatic beam, we develop the spectrum average mutual coherence function of the localized wave of Bessel−Gaussian ...

Certain geometric properties of generalized Bessel-Maitland function

, 2023
In the present study, we first introduce Generalized Bessel-Maitland function and then derive sufficient conditions under which the Generalized Bessel-Maitland function have geometric properties like univalency, starlikeness and convexity in the open ...

Uniform convergence of basic Fourier–Bessel series on a q-linear grid [PDF]

, 2019
We study Fourier–Bessel series on a q-linear grid, defined as expansions in complete q-orthogonal systems constructed with the Third Jackson q-Bessel function (or, the Hahn-Exton q-Bessel function), and obtain sufficient conditions for uniform ...
