The expression provides a closed form formula for the reproducing kernels of $h$-harmonics associated with symmetric groups when one of the components is a coordinate vector. The latter allows us to establish a sharp result for the Ces\\`aro summability of $h$-harmonic series on the unit sphere.", "revisions": [ { "version": "v1", "updated": "2020-04-18T23:04:05.000Z" } ], "analyses": { "subjects": [ "33C52", "42C05", "42B08", "44A30" ], "keywords": [ "symmetric groups", "unit sphere", "intertwining operator", "summability", "harmonic series" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
