On -norms on -graded tensor products
Vitonofrio Crismale, Stefano Rossi, Paola Zurlo
We systematically investigate -norms on the algebraic graded product of -graded -algebras. This requires to single out the notion of a compatible norm, that…
Spectral and ergodic properties of completely positive maps and decoherence
Francesco Fidaleo, Federico Ottomano, Stefano Rossi
In an attempt to propose more general conditions for decoherence to occur, we study spectral and ergodic properties of unital, completely positive maps on not necessarily unital $C…
Invariant Conditional Expectations and Unique Ergodicity for Anzai Skew-Products
Simone Del Vecchio, Francesco Fidaleo, Stefano Rossi
Anzai skew-products are shown to be uniquely ergodic with respect to the fixed-point subalgebra if and only if there is a unique conditional expectation onto such a subalgebra whic…
On the cyclic automorphism of the Cuntz algebra and its fixed-point algebra
Valeriano Aiello, Stefano Rossi
We investigate the structure of the fixed-point algebra of under the action of the cyclic permutation of the generating isometries. We prove that it is -isomorph…
Skew-product dynamical systems for crossed product -algebras and their ergodic properties
Simone Del Vecchio, Francesco Fidaleo, Stefano Rossi
Starting from a discrete -dynamical system , we define and study most of the main ergodic properties of the crossed product -dynamical system $(\m…
On the entropy and index of the winding endomorphisms of p-adic ring C-algebras
Valeriano Aiello, Stefano Rossi
For , the -adic ring -algebra is the universal -algebra generated by a unitary and an isometry such that and $\sum_{l=…
