On the Kernel of the Maximal Flat Radon Transform on Symmetric Spaces of Compact Type
Journal of Lie Theory, Volume 27 (2017) no. 3, pp. 623-636
Let $M$ be a Riemannian globally symmetric space of compact type, $M'$ its set of maximal flat totally geodesic tori, and Ad$(M)$ its adjoint space. We show that the kernel of the maximal flat Radon transform $\tau\colon L^2(M) \rightarrow L^2(M')$ is precisely the orthogonal complement of the image of the pullback map $L^2({\rm Ad}(M))\rightarrow L^2(M)$. In particular, we show that the maximal flat Radon transform is injective if and only if $M$ coincides with its adjoint space.
