Mixed weak estimates of Sawyer type for fractional integrals and some related operators
Fabio Berra, Marilina Carena, Gladis Pradolini
We prove mixed weak estimates of Sawyer type for fractional operators. More precisely, let be either the maximal fractional function or the fractional integral…

Mixed weak estimates of Sawyer type for commutators of singular integrals and related operators
Fabio Berra, Marilina Carena, Gladis Pradolini
We study mixed weak type inequalities for the commutator , where is a BMO function and is a Calderón-Zygmund operator. More precisely, we prove that for every …
