Hilbert transforms on graph products of finite von Neumann algebras
Xiao-Qi Lu, Runlian Xia
We study Hilbert transforms on graph products of finite von Neumann algebras, with particular interests on their boundedness on the associated noncommutative -spaces for $1<p<…

Xiaoge Lu, Zeke Yao, Xi Zhang
In this paper, we focus on the four-dimensional Thurston geometries whose isometry groups are four-dimensional, namely , and $\mathrm{Nil}^…

Hilbert transforms on Coxeter groups and groups acting on buildings
Xiao-Qi Lu, Runlian Xia
In this paper, we study Hilbert transforms and their boundedness on -spaces associated with Coxeter groups and groups acting on buildings. We establish new models for Hilbert…
