Weighted mixed inequalities for commutators of Schrödinger type operators
Fabio Berra, Gladis Pradolini, Jorgelina Recchi
We obtain weighted mixed inequalities for the first order commutator of singular integral operators in the Schrödinger setting. Concretely, for we give estimates of com…
Weighted mixed endpoint estimates of Fefferman-Stein type for commutators of singular integral operators
Fabio Berra, Gladis Pradolini, Jorgelina Recchi
We deal with mixed weak estimates of Fefferman-Stein type for higher order commutators of Calderón-Zygmund operators with BMO symbol. The results obtained are Fefferman-Stein inequ…
Some extensions of classes involving pair of weights related to the boundedness of multilinear commutators associated to generalized fractional integral operators
Fabio Berra, Gladis Pradolini, Jorgelina Recchi
We deal with the boundedness properties of higher order commutators related to some generalizations of the multilinear fractional integral operator of order , , from a pr…
On optimal parameters involved with two-weighted estimates of commutators of singular and fractional integral operators
Gladis Pradolini, Jorgelina Recchi
In this paper we prove two-weighted norm estimates for higher order commutator of singular integral and fractional type operators between weighted and certain spaces that inc…
Quantitative weighted mixed weak-type inequalities for classical operators
Sheldy Ombrosi, Carlos Perez, Jorgelina Recchi
We improve on several mixed weak type inequalities both for the Hardy-Littlewood maximal function and for Calderón-Zygmund operators. These type of inequalities were considered by…
