In particular, we show that the fractional Laplace operator maps Meijer G-functions of |x|^2, or generalized hypergeometric functions of -|x|^2, multiplied by a solid harmonic polynomial, into the same class of functions. As one important application of this result, we produce a complete system of eigenfunctions of the operator (1-|x|^2)_+^{alpha/2} (-Delta)^{alpha/2} with the Dirichlet boundary conditions outside of the unit ball. The latter result will be used to estimate the eigenvalues of the fractional Laplace operator in the unit ball in a companion paper \"Eigenvalues of the fractional Laplace operator in the unit ball\".", "revisions": [ { "version": "v1", "updated": "2015-09-28T22:40:10.000Z" } ], "analyses": { "keywords": [ "unit ball", "laplace operator maps meijer g-functions", "fractional laplace operator maps meijer", "dirichlet boundary conditions outside", "solid harmonic polynomial" ], "note": { "typesetting": "TeX", "pages": 20, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2015arXiv150908529D" } } }
