The Strong Matrix Weighted Maximal Operator

Emil Vuorinen

The purpose of this note is to prove that the strong Christ-Goldberg maximal function is bounded. This is a matrix weighted maximal operator appearing in the theory of matrix weigh…

Exotic Calderón-Zygmund operators

Tuomas Hytönen, Kangwei Li, Henri Martikainen +1

We study singular integral operators with kernels that are more singular than standard Calderón-Zygmund kernels, but less singular than bi-parameter product Calderón-Zygmund kernel…

Multiresolution analysis and Zygmund dilations

Tuomas Hytönen, Kangwei Li, Henri Martikainen +1

Zygmund dilations are a group of dilations lying in between the standard product theory and the one-parameter setting - in $\mathbb{R}^3 = \mathbb{R} \times \mathbb{R} \times \math…

Genuinely multilinear weighted estimates for singular integrals in product spaces

Kangwei Li, Henri Martikainen, Emil Vuorinen

We prove genuinely multilinear weighted estimates for singular integrals in product spaces. The estimates complete the qualitative weighted theory in this setting. Such estimates w…

Modern singular integral theory with mild kernel regularity

Emil Airta, Henri Martikainen, Emil Vuorinen

We present a framework based on modified dyadic shifts to prove multiple results of modern singular integral theory under mild kernel regularity. Using new optimized representation…

Banach-valued multilinear singular integrals with modulation invariance

Francesco Di Plinio, Kangwei Li, Henri Martikainen +1

We prove that the class of trilinear multiplier forms with singularity over a one dimensional subspace, including the bilinear Hilbert transform, admit bounded $L^{p}$ -extension to t…

Some new weighted estimates on product spaces

Emil Airta, Kangwei Li, Henri Martikainen +1

We complete our theory of weighted $L^{p} (w_{1}) \times L^{q} (w_{2}) \to L^{r} (w_{1}^{r / p} w_{2}^{r / q})$ estimates for bilinear bi-parameter Calderón--Zygmund operators under the assumption that…

Multilinear operator-valued Calderón-Zygmund theory

Francesco Di Plinio, Kangwei Li, Henri Martikainen +1

We develop a general theory of multilinear singular integrals with operator-valued kernels, acting on tuples of UMD Banach spaces. This, in particular, involves investigating multi…

Multilinear singular integrals on non-commutative $L^{p}$ spaces

Francesco Di Plinio, Kangwei Li, Henri Martikainen +1

We prove $L^{p}$ bounds for the extensions of standard multilinear Calderón-Zygmund operators to tuples of UMD spaces tied by a natural product structure. This can, for instance, mea…

Bloom type upper bounds in the product BMO setting

Kangwei Li, Henri Martikainen, Emil Vuorinen

For a bounded singular integral $T_{n}$ in $R^{n}$ and a bounded singular integral $T_{m}$ in $R^{m}$ 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 $T$ 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…

Commutators of bilinear bi-parameter singular integrals

Kangwei Li, Henri Martikainen, Emil Vuorinen

We study the boundedness properties of commutators formed by $b$ and $T$ , where $T$ is a bilinear bi-parameter singular integral satisfying natural $T 1$ type conditions and $b$ is…

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 $T$ . First, we prove a dyadic representation theorem starting from $T 1$ assumptions and apply it to sho…

Multi-parameter estimates via operator-valued shifts

Tuomas Hytönen, Henri Martikainen, Emil Vuorinen

We prove new results for multi-parameter singular integrals. For example, we prove that bi-parameter singular integrals in $R^{n + m}$ satisfying natural $T 1$ type condition…

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…

A Two-weight inequality between $L^{p} (ℓ^{2})$ and $L^{p}$

Non-homogeneous square functions on general sets: suppression and big pieces methods

Henri Martikainen, Mihalis Mourgoglou, Emil Vuorinen

We aim to showcase the wide applicability and power of the big pieces and suppression methods in the theory of local $T b$ theorems. The setting is new: we consider conical square f…
