On the sharp upper bound related to the weak Muckenhoupt-Wheeden conjecture
Andrei K. Lerner, Fedor Nazarov, Sheldy Ombrosi
We construct an example showing that the upper bound for the norm of the Hilbert transform cannot be improved in gen…
Commutators of singular integrals revisited
Andrei K. Lerner, Sheldy Ombrosi, Israel P. Rivera-Ríos
We obtain a Bloom-type characterization of the two-weighted boundedness of iterated commutators of singular integrals. The necessity is established for a rather wide class of opera…
Weighted mixed weak-type inequalities for multilinear operators
Kangwei Li, Sheldy J. Ombrosi, Belén Picardi
In this paper we present a theorem that generalizes Sawyer's classic result about mixed weighted inequalities to the multilinear context. Let and $ν= w_1^\f…
Proof of an extension of E. Sawyer's conjecture about weighted mixed weak-type estimates
Kangwei Li, Sheldy Ombrosi, Carlos Pérez
We show that if and , then there is a constant depending on the constant of and the constant of such that $$\Big\|\frac{ T(…
