Weighted -boundedness of commutators and paraproducts in the Bloom setting
Timo S. Hänninen, Emiel Lorist, Jaakko Sinko
As our main result, we supply the missing characterization of the boundedness of the commutator of a non-degenerate Calderón--Zygmund operator and pointwise…
Sparse domination for the lattice Hardy-Littlewood maximal operator
Timo S. Hänninen, Emiel Lorist
We study the domination of the lattice Hardy--Littlewood maximal operator by sparse operators in the setting of general Banach lattices. We prove that the admissible exponents of t…
Two-weight - bounds for positive dyadic operators: unified approach to and
Timo S. Hänninen, Tuomas P. Hytönen, Kangwei Li
We characterize the boundedness of positive dyadic operators of the form and the $L^{p_1}(σ_1)…
Operator-valued dyadic shifts and the T(1) theorem
Timo S. Hänninen, Tuomas P. Hytönen
In this paper we extend dyadic shifts and the dyadic representation theorem to an operator-valued setting: We first define operator-valued dyadic shifts and prove that they are bou…
Two weight inequality for vector-valued positive dyadic operators by parallel stopping cubes
Timo S. Hänninen
We study the vector-valued positive dyadic operator \[T_λ(fσ):=\sum_{Q\in\mathcal{D}} λ_Q \int_Q f \mathrm{d}σ1_Q,\] where the coefficients are p…
