Some remarks on the sparse dominations for commutators of multi(sub)linear operator

Journal of Inequalities and Applications, 2021
We establish pointwise sparse dominations for the iterated commutators of multi(sub)linear operators satisfying the W q $W_{q}$ condition. As consequences, we present some quantitative weighted estimates for the commutators.

Some estimates for commutators of bilinear pseudo-differential operators

Open Mathematics, 2022
We obtain a class of commutators of bilinear pseudo-differential operators on products of Hardy spaces by applying the accurate estimates of the Hörmander class. And we also prove another version of these types of commutators on Herz-type spaces.

AIMS Mathematics, 2021
In the present artice we discuss the weighted p-adic central bounded mean oscillations (CMO) and p-adic Lipschtiz estimates for the commutators of p-adic Hardy operator on two weighted p-adic Herz-type spaces.
