We consider weighted norm inequalities for the Riesz potentials $I_\alpha$, also referred to as fractional integral operators. First we prove mixed $A_p$-$A_\infty$ type estimates in the spirit of [13, 15, 17]. Then we prove strong and weak type inequalities in the case $p<q$ using the so-called log bump conditions. These results complement the strong type inequalities of P\'erez  and answer a conjecture from . For both sets of results our main tool is a corona decomposition adapted to…

In this paper, we introduce a new class of weights, the Aλ,∞$A_{\lambda, \infty}$ weights, which contains the classical A∞$A_{\infty}$ weights. We prove a mixed Ap,q$A_{p,q}$–Aλ,∞$A_{\lambda,\infty}$
Two weight norm inequalities for fractional integral operators and commutators
In these lecture notes we describe some recent work on two weight norm inequalities for fractional integral operators, also known as Riesz potentials, and for commutators of fractional integrals.

In this paper we investigate weighted norm inequalities for the commutator of a fractional integral operator and multiplication by a function. In particular, we show that, for \$\mu,\lambda\in

We prove a general sparse domination theorem in a space of homogeneous type, in which a vector-valued operator is controlled pointwise by a positive, local expression called a sparse operator. We use
A Fractional Muckenhoupt–Wheeden Theorem and its Consequences

In the 1970s Muckenhoupt and Wheeden made several conjectures relating two weight norm inequalities for the Hardy-Littlewood maximal operator to such inequalities for singular integrals. Using
Ap-A∞ estimates for multilinear maximal and sparse operators
We obtain mixed Ap-A∞ estimates for a large family of multilinear maximal and sparse operators. Operators from this family are known to control for instance multilinear Calderón-Zygmund operators,

We prove some Sawyer-type characterizations for multilinear fractional maximal function for the upper triangle case. We also provide some two-weight norm estimates for this operator. As one of the

AbstractIn this paper, we give a characterization of the two weight strong and weak type norm inequalities for the bilinear fractional integrals in terms of Sawyer type testing conditions. Namely, we

In this paper, we study weighted inequalities for multilinear fractional maximal operators and fractional integrals. We prove sharp weighted Lebesgue space estimates for both operators when the

For sparse operators including majorants of singular integral, square function, and fractional integral operators in a uniform manner, we prove sharp off-diagonal two-weight estimates of mixed type
