Infinite twisted -tensor product and symmetric states
Francesco Fidaleo, Elia Vincenzi
The twisted -tensor product was exhaustively investigated by the authors in two previous papers. In this new context, generalising the usual tensor product and the Fermi one,…

Dominance and equivalence for states on -algebras: Quasi-Invariant states
Ameur Dhahri, Francesco Fidaleo, Chul Ki Ko +1
We study the noncommutative generalization of measure-theoretic dominance and equivalence of states on -algebras to explore quasi-invariance under group actions. For a dominat…

On the reduction theory of -algebras by Hilbert modules
Francesco Fidaleo, Laszlo Zsido
We deal with the reduction theory of a -algebra along a -subalgebra of the centre of . This is done by using Hilbert modules naturally constructed by suitable…
