Application of general approach to the theory of Morrey-type spaces. (English) Zbl 1466.46017

Summary: In this paper, we generalize constructions of Morrey spaces by using as a basic space a general rearrangement invariant space \(E(\mathbb R^n)\) instead of \(L_p((\mathbb R^n)\) and a general ideal space \(F((\mathbb R_+)\) for outer norm instead of \(L_\infty((\mathbb R_+)\) or \(L_{q, w}((\mathbb R_+)\). Embeddings, nontriviality conditions, and inclusion into a general concept of ideal spaces and generalized rearrangement invariant spaces are discussed.
