From the abstract: The Poisson transform maps sections of vector bundles over a parabolic geometry \(G/P\) to sections of vector bundles over a symmetric space \(G/K\). The parabolic geometry can be understood as a (part of the) boundary of the symmetric space. We show that the Poisson transform intertwines invariant differential operators on these spaces, generalizing the results of Ørsted and Koranyi and Reimann.
