Vector-Valued Singular Integrals on Locally Doubling Spaces

Mattia Calzi, Elena Rizzo

We prove vector-valued boundedness of (suitable) Calderon-Zygmund operators and of the (truncated) Hardy-Littlewood maximal function on a connected locally doubling metric measure…

Clark Measures Associated with Rational Inner Functions on Bounded Symmetric Domains

Mattia Calzi

Given a bounded symmetric domain $D$ in $C^{n}$ , we consider the Clark measures $I^¼_{I^} \pm$ , $I^\pm \in T$ , associated with a rational inner function $I ¨ $ from $D$ into the u…

Sharp defective log-Sobolev inequalities on H-type groups

Gioacchino Antonelli, Mattia Calzi, Maria Gordina

In this paper we prove a sharp defective log-Sobolev inequality on H-type groups. Then we use such an inequality to show exponential integrability of Lipschitz functions with respe…
