Modified $ q$-Bessel functions and $ q$-Macdonald functions

Sbornik: Mathematics, 1996
Summary: The \(q\)-analogues of modified Bessel functions and Macdonald functions are defined in this paper. As in the case of \(q\)-Bessel functions introduced by Jackson, there are two kinds of these functions. Like their classical prototypes, they arise in harmonic analysis on quantum symmetric spaces.

Mathematical Software for Modified Bessel Functions

2014
The high-quality mathematical software for the computation of modified Bessel functions of the second kind with integer, imaginary and complex order and real argument is elaborated. The value of function may be evaluated with high precision for given value of the independent argument x and order r.

On an integral with modified Bessel function

Journal of Physics A: Mathematical and General, 1992
The definite integral over I0(z) evaluated by Bakulev (1991) is shown to be a special case of a tabulated integral.

On an integral with modified Bessel function

Journal of Physics A: Mathematical and General, 1991
Using two different methods of calculations of the imaginary part of some Feynman integral (Cutkosky rule and the double transformation), the author obtains a formula \[ \int_ 0^ a I_ 0(z)\cosh \bigl( A\sqrt{a^ 2-z^ 2}\bigr) {{z dz} \over {\sqrt{a^ 2-z^ 2}}}= {{\sinh(a \sqrt{1-A^ 2})} \over {\sqrt{1+A^ 2}}}, \] where \(I_ 0(z)\) is a modified Bessel ...

Note on Asymptotic Expansions of Modified Bessel Functions

Journal of the Society for Industrial and Applied Mathematics, 1961
In a recent paper the author [1] extended an early result of Stieltjes, as an aid in the calculation of Bessel functions of orders 0 and 1 from their truncated asymptotic expansions. It is the purpose of this short note to extend these results to include modified Bessel functions.
