For the Fourier transform on the Lobachevsky plane we establish a similar correspondence for a certain family of differential operators. It appears that differential operators on the Lobachevsky plane correspond to differential-difference operators in the Fourier-image, where shift operators act in the imaginary direction, i.e., a direction transversal to the integration contour in the Plancherel formula.", "revisions": [ { "version": "v1", "updated": "2020-06-20T14:09:10.000Z" } ], "analyses": { "subjects": [ "43A85", "43A32", "44A99", "22E46" ], "keywords": [ "operational calculus", "differential operators", "lobachevsky plane correspond", "shift operators act", "classical fourier transform" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
