In particular, various impacts of non-isotropic dilations are considered. Firstly, we provide a generic scheme that allows us to deduce the sparse domination bounds for global maximal functions under the assumption that the corresponding localized maximal functions satisfy the $L^{p}$ improving properties. Secondly, for the localized maximal functions with non-isotropic dilations of curves and hypersurfaces whose curvatures vanish to finite order at some points, we establish the $L^{p}\\rightarrow L^{q}$ bounds $(q >p)$. As a corollary, we obtain the weighted inequalities for the corresponding global maximal functions, which generalize the known unweighted estimates.", "revisions": [ { "version": "v2", "updated": "2022-02-23T14:17:56.000Z" } ], "analyses": { "subjects": [ "42B20", "42B25" ], "keywords": [ "non-isotropic dilations", "corresponding localized maximal functions satisfy", "sparse domination bounds", "corresponding global maximal functions", "finite type curves" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
