We show that the generalization with Dunkl derivative of the $z$-component of the angular momentum is what allows the separation of variables of the $DKG$ equation. Then, we show that $DKG$ equations for the $2D$ Coulomb potential and the Klein-Gordon oscillator are exactly solvable. For each of the problems, we find the energy spectrum from an algebraic point of view by introducing suitable sets of operators which close the $su(1,1)$ algebra and use the unitary theory of representations. Also, we find analytically the energy spectrum and eigenfunctions of the $DKG$ equations for both problems. Finally, we show that when the parameters of the Dunkl derivative vanish, our results are suitably reduced to those reported in the literature for these $2D$ problems.", "revisions": [ { "version": "v1", "updated": "2020-08-30T15:53:57.000Z" } ], "analyses": { "keywords": [ "klein-gordon oscillator", "coulomb potential", "exact solutions", "dunkl-klein-gordon equation", "energy spectrum" ], "note": { "typesetting": "TeX", "pages": 15, "language": "en", "license": "arXiv", "status": "editable" } } }
