ABSTRACT: In expansions of arbitrary functions in Bessel functions or Spherical Bessel functions, a dual partner set of polynomials play a role. For the Bessel functions, these are the Chebyshev ...

ABSTRACT: Series expansion of single variable functions is represented in Fourier-Bessel form with unknown coefficients. The proposed series expansions are derived for arbitrary radial boundaries in ...

Abstract: This appendix talks about Bessel functions. Zeros of the ordinary Bessel function and its derivative can be approximated by the first two terms of McMahon's expansion. The chapter shows the ...

Abstract: This paper introduces a novel theoretical framework for sequence spaces of fuzzy numbers based on Bessel statistical convergence and strong Bessel summability. The proposed approach ...

THE function to which these volumes are devoted received its name from the astronomer Bessel, 1824, on introducing it for the coefficients in the expansion of radius vector, and true or eccentric ...

THE worthy completion of a long and arduous task will always draw from the beholder the tribute of an almost personal gratification. Our sympathy and interest are at once enlisted by the opening ...

The following function computes the logarithm of the modified Bessel function of the 1st kind I(nu, z). It uses the scipy method and extends it when it is not tractable, using 2 different methods (1 ...
