Weighted $L^{p} \to L^{q}$ -boundedness of commutators and paraproducts in the Bloom setting

Timo S. HÃ¤nninen, Emiel Lorist, Jaakko Sinko

As our main result, we supply the missing characterization of the $L^{p} (I^¼) \to L^{q} (I^»)$ boundedness of the commutator of a non-degenerate CalderÃ³n--Zygmund operator $T$ and pointwi…

Testing compactness of linear operators

Timo S. HÃ¤nninen, Tuomas V. Oikari

Let $(F_{i})$ be a sequence of sets in a Banach space $X$ . For what sequences does the condition $i \to \infty lim sup f_{i} \in F_{i} sup ∥ T f_{i} ∥_{Y} = 0$ hold for every Banach spac…
