On subordinated semigroups and Hardy spaces associated to fractional powers of operators

The Anh Bui, Michael G. Cowling, Xuan Thinh Duong

Let $L$ be a positive self-adjoint operator on $L^{2} (X)$ , where $X$ is a $σ$ -finite metric measure space. When $α \in (0, 1)$ , the subordinated semigroup $\{\exp(-tL^α):t \in \mathbb{…

Brascamp--Lieb inequalities on locally compact abelian groups

Jonathan Bennett, Michael G. Cowling

We establish a structure theorem for the Brascamp--Lieb constant formulated in the general setting of locally compact abelian groups. This extends and unifies the finiteness charac…

An endpoint estimate for product singular integral operators on stratified Lie groups

Michael G. Cowling, Ming-Yi Lee, Ji Li +1

We establish hyperweak boundedness of area functions, square functions, maximal operators and Calderón--Zygmund operators on products of two stratified Lie groups.
