Characterizations of a limiting class B∞ of Békollé–Bonami weights [PDF]
, 2019 We explore properties of the class of Békollé–Bonami weights B∞ introduced by the authors in a previous work. Although Békollé–Bonami weights are known to be ill-behaved because they do not satisfy a reverse Hölder property, we prove that when ...

Variable Muckenhoupt weights with applications in approximation
, 2021 Variable Muckenhoupt weights are considered in variable exponent Lebesgue spaces. Applications are given for polynomial approximation in these spaces. Boundedness of averaging operator is proved to gain a transference result. Almost all weighted norm inequalities are obtained using this transference result.

Strong $A_\infty$-weights are $A_\infty$-weights on metric spaces [PDF]
, 2011 We prove that every strong A(infinity)-weight is a Muckenhoupt weight in Ahlfors-regular metric measure spaces that support a Poincare inequality. We also explore the relations between various definitions for A(infinity)-weights in this setting, since ...

Optimal factorization of Muckenhoupt weights [PDF]
, 2008 Peter Jones' theorem on the factorization of Ap weights is sharpened for weights with bounds near 1, allowing the factorization to be performed continuously near the limiting, unweighted case.

Variable Muckenhoupt $A_\infty$ Weights
In this article, with introducing concepts of variable scalar $\mathcal{A}_{p(\cdot),\infty}$ weights and variable matrix $\mathscr{A}_{p(\cdot),\infty}$ weights, we seek a comprehensive theory of $A_\infty$ weights within the framework of variable exponent spaces.

Nonlocal equations with degenerate weights [PDF]
We introduce fractional weighted Sobolev spaces with degenerate weights. For these spaces we provide embeddings and Poincaré inequalities. When the order of fractional differentiability goes to $0$ or $1$, we recover the weighted Lebesgue and Sobolev ...
