A Modern Functional Analytic Tour of the Fourier-Bessel Transform
Abstract
In this paper, we review the theory of the Fourier-Bessel transform. Many of the standard results for the Fourier-Bessel transform have become folklore results or predate modern functional analysis and rely on hard analysis proofs that miss the elegance of more modern machinery. This review aims to centralize some of the basic theory while providing some new proofs and approaches that can be applied to other integral transforms beyond the Fourier and Fourier-Bessel transform.
