We establish a wide range of $L^p$ estimates for this operator when $v$ is a measurable, non-vanishing, one-variable vector field in $\\bbr ^2$. Aside from an $L^2$ estimate following from a simple trick with Carleson's theorem, these estimates were unknown previously. This paper is closely related to a recent paper of the first author (\\cite{B2}).", "revisions": [ { "version": "v1", "updated": "2011-09-29T04:31:42.000Z" } ], "analyses": { "subjects": [ "42B20", "42B25" ], "keywords": [ "one-variable vector field", "hilbert transform", "wide range", "simple trick", "carlesons theorem" ], "note": { "typesetting": "TeX", "pages": 25, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1109.6396B" } } }
