The solution leads us to first consider when this space is contained in the sum of (L¹ + L∞)(R, µ) and the finalcondition is given in terms of embeddings for weighted Lorentz spacesengAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/journal articlehttps://doi.org/10.1016/j.jfa.2024.110454open accessWeighted inequalitiesRearrangement-invariant hullLorentz spacesMatemáticas (Matemáticas)12 Matemáticas
