Abstract:
The corrections and additions are made in the context of Hankel transforms which generalize the Fourier transforms of radial functions. The following question is studied: given two closed ideals ${I_1}$ and ${I_2}$ in the algebra of Hankel transforms such that both have the same spectrum and ${I_1} \subset {I_2}$, when is there a closed ideal $I$ such that ${I_1} \subset I \subset {I_2}$?References
