Vector-valued operators, optimal weighted estimates and the condition
Maria Eugenia Cejas, Kangwei Li, Carlos Perez +1
Sharp weighted estimates are obtained for vector-valued extensions of the Hardy-Littlewood maximal operator, Calderón-Zygmund operators and Coifman-Rochberg-Weiss commutator. Those…
Bilinear Calderón-Zygmund theory on product spaces
Kangwei Li, Henri Martikainen, Emil Vuorinen
We develop a wide general theory of bilinear bi-parameter singular integrals . First, we prove a dyadic representation theorem starting from assumptions and apply it to sho…
Sparse bounds for maximal rough singular integrals via the Fourier transform
Francesco Di Plinio, Tuomas P. Hytönen, Kangwei Li
We prove that the class of convolution-type kernels satisfying suitable decay conditions of the Fourier transform, appearing in the works of Christ, Christ-Rubio de Francia, and Du…
Bilinear representation theorem
Kangwei Li, Henri Martikainen, Yumeng Ou +1
We represent a general bilinear Calderón-Zygmund operator as a sum of simple dyadic operators. The appearing dyadic operators also admit a simple proof of a sparse bound. In partic…
Weighted mixed weak-type inequalities for multilinear operators
Kangwei Li, Sheldy J. Ombrosi, Belén Picardi
In this paper we present a theorem that generalizes Sawyer's classic result about mixed weighted inequalities to the multilinear context. Let and $ν= w_1^\f…
Sharp weighted estimates involving one supremum
Kangwei Li
In this note, we study the sharp weighted estimate involving one supremum. In particular, we give a positive answer to an open question raised by Lerner and Moen \cite{LM}. We also…
