De finetti-type theorems on quasi-local algebras and infinite fermi tensor products [PDF]
Infinite Dimensional Analysis Quantum Probability and Related Topics, 2022 Local actions of PN, the group of finite permutations on N, on quasi-local algebras are defined and proved to be PNabelian. It turns out that invariant states under local actions are automatically even, and extreme invariant states are strongly ...

Symmetric states for C*-fermi systems [PDF]
Reviews in Mathematical Physics, 2022 In the present note, which is the second part of a work concerning the study of the set of the symmetric states, we introduce the extension of the Klein transformation for general Fermi tensor product of two Z graded C-algebras, under the condition that ...

On the Best Constants in Some Non‐Commutative Martingale Inequalities [PDF]
, 2005 The optimal orders are determined for the best constants in the non‐commutative Burkholder–Gundy, Doob and Stein inequalities obtained recently in non‐commutative martingale theory. 2000 Mathematics Subject Classification 46L53, 46L51.

An equivalent quasinorm for the Lipschitz space of noncommutative martingales
Open Mathematics, 2020 In this paper, an equivalent quasinorm for the Lipschitz space of noncommutative martingales is presented. As an application, we obtain the duality theorem between the noncommutative martingale Hardy space hpc(ℳ){h}_{p}^{c}( {\mathcal M} ) (resp.

The Curvature and Index of Completely Positive Maps [PDF]
, 2002 We study conjugacy invariants for completely positive maps that are inspired by the concept of curvature introduced for commuting d‐tuples of contractions by Arveson.

Gundy's Decomposition for Non‐Commutative Martingales and Applications [PDF]
, 2004 We provide an analogue of Gundy's decomposition for L1‐bounded non‐commutative martingales. An important difference from the classical case is that for any L1‐bounded non‐commutative martingale, the decomposition consists of four martingales.

State Determination and Sufficiency of Observables [PDF]
, 2013 Informational completeness and the possibility of state distinction and determination are among the more important issues of quantum statistics. We use spectral and semispectral (POV) measures to analyse these questions.

Matrices induced by arithmetic functions, primes and groupoid actions of directed graphs
Special Matrices, 2015 In this paper, we study groupoid actions acting on arithmetic functions. In particular, we are interested in the cases where groupoids are generated by directed graphs. By defining an injective map α from the graph groupoid G of a directed graph G to the

Matrices induced by arithmetic functions acting on certain Krein spaces
Special Matrices, 2017 In this paper, we study matrices induced by arithmetic functions under certain Krein-space representations induced by (multi-)primes less than or equal to fixed positive real numbers.
