Query: Rotation invariant ultradistributions   We 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 $\mathbb{R}^{n}$. Our results apply to
both the quasianalytic and the non-quasianalytic case.
