Abstract:
For a certain Fréchet space $F$ consisting of complex-valued ${C^\infty }$ functions defined on $I = (0,\infty )$ and characterized by their asymptotic behaviour near the boundaries, we show that: (I) The pseudo-differential operator ${( - {x^{ - 1}}D)^\nu },\nu \in \mathbb {R},D = d/dx$, is an automorphism (in the topological sense) on $F$; (II) ${( - {x^{ - 1}}D)^\nu }$ is almost an inverse of the Hankel transform ${h_\nu }$ in the sense that \[ {h_\nu } \circ {({x^{ - 1}}D)^\nu }(\varphi ) = {h_0}(\varphi ),\quad \forall \varphi \in F,\quad \forall \nu \in \mathbb {R};\] (III) ${( - {x^{ - 1}}D)^\nu }$ has a Fourier-Bessel series representation on a subspace ${F_b} \subset F$ and also on its dual ${F’_b}$.References
