The results obtained are Fefferman-Stein inequalities that include the estimates proved in \\cite{BCP22(JMS)} for the case of singular integral operators, as well as the classical weak endpoint estimate for commutators given in \\cite{PP01}. We also consider commutators of operators involving less regular kernels satisfying an $L^{\\Phi}$--H\\\"ormander condition. Particularly, the obtained results contain some previous estimates proved in \\cite{BCP22(JMS)} and \\cite{Lorente-Martell-Perez-Riveros}.", "revisions": [ { "version": "v1", "updated": "2023-09-14T12:24:05.000Z" } ], "analyses": { "subjects": [ "42B20", "42B25" ], "keywords": [ "singular integral operators", "weighted mixed endpoint estimates", "fefferman-stein type", "higher order commutators", "classical weak endpoint estimate" ], "note": { "typesetting": "TeX", "pages": 26, "language": "en", "license": "arXiv", "status": "editable" } } }
