Sharp weighted weak-type bounds for commutators of singular integrals

Adam Mair, Óscar Andrés Ramírez, Cody B. Stockdale

We establish sharp weak-type bounds for commutators of Calderón--Zygmund operators and symbols with respect to weights. We prove that the bound \lo…

The weak-type (1,1) bound for the Hardy--Littlewood maximal function is

Daniel Spector, Cody B. Stockdale

We prove a weak-type estimate for the centered Hardy--Littlewood maximal function with respect to Euclidean balls with dimensional dependence . This imp…

A dimension-free weak-type bound for the vector Riesz transform on

Yuyuan Ouyang, Daniel Spector, Cody B. Stockdale

We show that the best constant in the weak-type bound for the vector Riesz transform on is at most , independent of the dimension . The proof relies on…

Local dyadic fractional Sobolev spaces: paraproducts, commutators, and the algebra property

Valentia Fragkiadaki, Mishko Mitkovski, Cody B. Stockdale

We characterize the boundedness and compactness of dyadic paraproducts on local dyadic fractional Sobolev spaces, . We apply this result to establish the algebra property for…

On the compactness of bi-parameter singular integrals

Cody B. Stockdale, Cody Waters

We establish a new theorem for the compactness of bi-parameter Calderón-Zygmund singular integral operators. Namely, we show that if a bi-parameter CZO satisfies the produ…

An atomic decomposition for functions of bounded variation

Daniel Spector, Cody B. Stockdale, Dmitriy Stolyarov

In this paper, we give a decomposition of the gradient measure of an arbitrary function of bounded variation into a sum of atoms , where is a set of finite p…

Compact pseudodifferential and Fourier integral operators via localization

Cody B. Stockdale, Cody Waters

We present a general framework of localized operators, i.e., operators whose matrix coefficients with respect to the Gabor frame are concentrated on the diagonal. We show that loca…

Weighted weak-type bounds for multilinear singular integrals

Zoe Nieraeth, Cody B. Stockdale, Brandon Sweeting

We establish analogs of sharp weighted weak-type bounds for -sublinear operators satisfying sparse form domination, including multilinear Calderón-Zygmund singular integrals. Ou…
