We obtain the energies and wave functions of reduced two-dimensional Schrodinger equation by using the double
Fourier-Bessel series expansion method.
These properties of functions [a.sup.(i).sub.m] (r), i = 1, 2, are sufficient in order to expand them into
Fourier-Bessel seriesin this study, the authors used the
Fourier-Bessel series and approximated the half space as a large-diameter elastic cylinder.
[7] gave another method to compute zero-order quasi-discrete HT by approximating the input function by a
Fourier-Bessel series over a finite integration interval.
It is identical to our LFE-FC-7 stencil in Section 4.1 derived from using a spherical
Fourier-Bessel series (SFBS).
The longitudinal components of the fields are developed into the
Fourier-Bessel series. The transverse components of the fields are expressed as functions of the longitudinal components in the Laplace plane and are obtained by using the inverse Laplace transform by the residue method.
Therefore, we can consider [p.sub.m] the expansion coefficients for the
Fourier-Bessel series.
Exact solutions were obtained as infinite
Fourier-Bessel series. Wood [6] has considered the general case of helical flow of an Oldroyd-B fluid, due to the combined action of rotating cylinders (with constant angular velocities) and a constant axial pressure gradient.
Reducing the Gibbs phenomenon in a
Fourier-Bessel series, Hankel and Fourier transform.

For the 3-D homogeneous Helmholtz equation, we expand the local field at a given point by spherical
Fourier-Bessel series (SFB) and through an elaborated process, derive the sixth-order accurate analytical formulation, called LFE3D-27.
