The $C_{s,l}$ descend to invariant differential operators on the corresponding Grassmannian, which is a compact symmetric space, and we determine the image of the $C_{s,l}$ under the Harish-Chandra homomorphism. We also obtain analogous results for corresponding operators on the non-compact duals of the Grassmannians, and for line bundles. As an application we obtain a Radon inversion formula, which generalizes a recent result of B. Rubin for real Grassmannians.", "revisions": [ { "version": "v1", "updated": "2015-11-16T14:17:46.000Z" } ], "analyses": { "keywords": [ "radon transform", "capelli identity", "grassmannian", "capelli-type invariant differential operators", "radon inversion formula" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2015arXiv151104966S" } } }
