Compactness of commutator of Riesz transforms in the two weight setting
Michael Lacey, Ji Li
We characterize the compactness of commutators in the Bloom setting. Namely, for a suitably non-degenerate Calderón--Zygmund operator , and a pair of weights , the…
A note on commutators on weighted Morrey spaces on spaces of homogeneous type
Ruming Gong, Ji Li, Elodie Pozzi +1
In this paper we study the boundedness and compactness characterizations of the commutator of Calderón-Zygmund operators on spaces of homogeneous type in the sense of…
Quantitative weighted bounds for the -variation of singular integrals with rough kernels
Yanping Chen, Guixiang Hong, Ji Li
In this paper, we study the quantitative weighted bounds for the -variational singular integral operators with rough kernels. The main result is for the sharp truncated singular…
Quantitative weighted bounds for Calderón commutator with rough kernel
Yanping Chen, Ji Li
We consider weighted boundedness ( and a Muckenhoupt weight) of the Calderón commutator associated with rough homogeneous kernel, und…
A two weight inequality for Calderón-Zygmund operators on spaces of homogeneous type with applications
Xuan Thinh Duong, Ji Li, Eric T. Sawyer +3
Let be a space of homogeneous type in the sense of Coifman and Weiss, i.e. is a quasi metric on and is a positive measure satisfying the doubling condition. S…
Zygmund type and flag type maximal functions, and sparse operators
Guillermo J. Flores, Ji Li, Lesley A. Ward
We prove that the maximal functions associated with a Zygmund dilation dyadic structure in three-dimensional Euclidean space, and with the flag dyadic structure in two-dimensional…
Weighted embeddings for function spaces associated with Hermite expansions
The Anh Bui, Ji Li, Fu Ken Ly
We study weighted Besov and Triebel--Lizorkin spaces associated with Hermite expansions and obtain (i) frame decompositions, and (ii) characterizations of continuous Sobolev-type e…
