Abstract

For every cube Q⊂Rn we let XQ be a quasi-Banach function space over Q such that ‖χQ‖XQ≃1, and for X={XQ} define (Formula presented.) We study necessary and sufficient conditions on X such that (Formula presented.) In particular, we give a full characterization of the embedding BMO↪BMOX in terms of so-called sparse collections of cubes and we give easily checkable and rather weak sufficient conditions for the embedding BMOX↪BMO. Our main theorems recover and improve all previously known results in this area.
