Reflection positivity and Hankel operators -- the multiplicity free case
Maria Stella Adamo, Karl-Hermann Neeb, Jonas Schober
We analyze reflection positive representations in terms of positive Hankel operators. This is motivated by the fact that positive Hankel operators are described in terms of their C…
On some applications of representable and continuous functionals of Banach quasi *-algebras
Maria Stella Adamo
This survey aims to highlight some of the consequences that representable (and continuous) functionals have in the framework of Banach quasi *-algebras. In particular, we look at t…
Tensor products of normed and Banach quasi *-algebras
Maria Stella Adamo, Maria Fragoulopoulou
Quasi *-algebras form an essential class of partial *-algebras, which are algebras of unbounded operators. In this work, we aim to construct tensor products of normed, respectively…
About tensor products of Hilbert quasi *-algebras and their representability properties
Maria Stella Adamo
This note aims to investigate the tensor product of two given Hilbert quasi *-algebras and its properties. The construction proposed in this note turns out to be again a Hilbert qu…
The interplay between representable functionals and derivations on Banach quasi *-algebras
Maria Stella Adamo
This note aims to highlight the link between representable functionals and derivations on a Banach quasi *-algebra, i.e. a mathematical structure that can be seen as the completion…
Unbounded derivations and *-automorphisms groups of Banach quasi *-algebras
Maria Stella Adamo, Camillo Trapani
This paper is devoted to the study of unbounded derivations on Banach quasi *-algebras with a particular emphasis to the case when they are infinitesimal generators of one paramete…
