Nonhomogeneous $T (1)$ Theorem on Product Quasimetric Spaces

Ji Li, Trang T. T. Nguyen, Lesley A. Ward +1

In this paper, we provide a non-homogeneous $T (1)$ theorem on product spaces $(X_{1} \times X_{2}, ρ_{1} \times ρ_{2}, μ_{1} \times μ_{2})$ equipped with a quasimetric $ρ_{1} \times ρ_{2}$ and a B…

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…

Weak-type endpoint bounds for Bochner-Riesz means for the Hermite operator

Peng Chen, Ji Li, Lesley A. Ward +1

We obtain weak-type $(p, p)$ endpoint bounds for Bochner-Riesz means for the Hermite operator $H = - Δ + ∣ x ∣^{2}$ in $R^{n}, n \geq 2$ and for other related operators for $1\leq p\…

Characterization of compactness of commutators of bilinear singular integral operators

Lucas Chaffee, Peng Chen, Yanchang Han +2

The commutators of bilinear Calderón-Zygmund operators and point-wise multiplication with a symbol in $c m o$ are bilinear compact operators on product of Lebesgue spaces. This work…
