Reproducing kernel Hilbert spaces and Mercer theorem

Claudio Carmeli, Ernesto De Vito, Alessandro Toigo

We characterize the reproducing kernel Hilbert spaces whose elements are $p$ -integrable functions in terms of the boundedness of the integral operator whose kernel is the reproduci…

Positive operator valued measures covariant with respect to an Abelian group

G. Cassinelli, E. De Vito, A. Toigo

Given a unitary representation $U$ of an Abelian group $G$ and a subgroup $H$ , we characterise the positive operator valued quotient group $G / H$ and covariant with respect to $U$ .

Square-integrability modulo a subgroup

G. Cassinelli, E. De Vito

A new proof of Imprimitivity theorem for transitive systems of covariance is given and a definition of square-integrable representation modulo a subgroup is proposed. This clarifie…
