Here $\\mu$ is allowed to be a non-homogeneous measure in $\\mathbb{R}^n$. In this paper we prove a boundedness result assuming local $L^q$ type testing conditions in the difficult range $q \\in (1,2)$. Our theorem is a non-homogeneous version of a result of S. Hofmann valid for the Lebesgue measure. It is also an extension of the recent results of M. Lacey and the first named author where non-homogeneous local $L^2$ testing conditions have been considered.", "revisions": [ { "version": "v1", "updated": "2014-01-21T20:44:56.000Z" } ], "analyses": { "subjects": [ "42B20" ], "keywords": [ "type testing conditions", "non-homogeneous square functions", "boundedness result assuming local", "upper half-space", "hofmann valid" ], "note": { "typesetting": "TeX", "pages": 29, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014arXiv1401.5457M" } } }
