Restricted testing for the Hardy-Littlewood maximal function
Kangwei Li, Eric T. Sawyer
We answer a special case of a question of T. Hytonen regarding the two weight norm inequality for the maximal function M in the affirmative, namely that there is a constant D > 1,…
Bloom type upper bounds in the product BMO setting
Kangwei Li, Henri Martikainen, Emil Vuorinen
For a bounded singular integral in and a bounded singular integral in we prove that $$ \| [T_n^1, [b, T_m^2]] \|_{L^p(μ) \to L^p(λ)} \less…
Quasi-Banach estimates of commutators of bilinear bi-parameter singular integrals: paraproducts
Kangwei Li, Henri Martikainen, Emil Vuorinen
We complete our boundedness theory of commutators of bilinear bi-parameter singular integrals by establishing the following result. If is a bilinear bi-parameter singular integ…
Bloom type inequality for bi-parameter singular integrals: efficient proof and iterated commutators
Kangwei Li, Henri Martikainen, Emil Vuorinen
Utilising some recent ideas from our bilinear bi-parameter theory, we give an efficient proof of a two-weight Bloom type inequality for iterated commutators of linear bi-parameter…
Flow with density and transport equation in
Renjin Jiang, Kangwei Li, Jie Xiao
We show that, if has spatial derivative in the John-Nirenberg space , then it generalizes a unique flow $ϕ(…
Commutators of bilinear bi-parameter singular integrals
Kangwei Li, Henri Martikainen, Emil Vuorinen
We study the boundedness properties of commutators formed by and , where is a bilinear bi-parameter singular integral satisfying natural type conditions and is…
