Besov Space, Schatten Classes And Commutators Of Riesz Transforms Associated With The Neumann Laplacian
Zhijie Fan, Michael Lacey, Ji Li +2
This article provides a deeper study of the Riesz transform commutators associated with the Neumann Laplacian operator on . Along the line of singular value esti…

Compactness of the Bloom sparse operators and applications
Peng Chen, Michael Lacey, Ji Li +1
We establish the characterization of compactness for the sparse operator (associated with symbol in weighted VMO space) in the two weight setting on the spaces of homogeneous type…

Schatten classes and commutator in the two weight setting, I. Hilbert transform
Michael Lacey, Ji Li, Brett D. Wick
We characterize the Hilbert--Schmidt class membership of commutator with the Hilbert transform in the two weight setting. The characterization depends upon the symbol of the commut…
