In this paper by extending slightly the idea employed in [5], we give an alternative proof of this fact and then we extend this proposition so that we can include some related function s

We prove that for such quasi-Banach space ., there are convenient Hilbert spaces, ., with normalized Hermite functions as orthonormal bases and such that . lies between ., and the latter spaces lie between ..

https://doi.org/10.1057/9781137492975We prove that an ultradistribution is rotation invariant if and only if it coincides with its spherical mean. For it, we study the problem of spherical representations of ultradistributions on ℝ.. Our results apply to both the quasianalytic and the non-quasianalytic case.
