The inversion of the X-ray Transform on a Compact Symmetric Space
Sigurdur Helgason
The X-ray transform on a compact symmetric space M is here inverted by means of an explicit inversion formula. The proof uses the conjugacy of the minimal closed geodesics in M and…

The Abel, Fourier and Radon transforms on symmetric spaces
Sigurdur Helgason
In this paper we prove a new inversion theorem and a refinement of an old support theorem for two Radon transforms on a symmetric space. Included are some new identities for the Ab…
