“…In the present work, we continue the analysis begun in previous literature [
2, 6] to understand more the canonical Fourier–Bessel transform. We will here concentrate to establish the finite canonical Fourier–Bessel transform operator
on
, the self‐adjoint compact operator
and the corresponding eigenfunctions
on
, and the Paley–Wiener space of canonical Bessel band‐limited functions.…”
