A generalization of the Pistone-Sempi argument, demonstrating the utility of non-commutative Orlicz spaces, is presented. The question of lifting positive maps defined on von Neumann algebra to maps on corresponding noncommutative Orlicz spaces is discussed. In particular, we describe those Jordan *-morphisms on semifinite von Neumann algebras which in a canonical way induce quantum composition operators on noncommutative Orlicz spaces. Consequently, it is proved that the framework of… 
Noncommutative Orlicz spaces over W*-algebras
Using the Falcone--Takesaki theory of noncommutative integration, we construct a family of noncommutative Orlicz spaces that are canonically associated to an arbitrary W*-algebra without any choice
A crossed product approach to Orlicz spaces
We show how the known theory of noncommutative Orlicz spaces for semifinite von Neumann algebras equipped with an fns trace, may be recovered using crossed product techniques. Then using this as a
Multipliers on noncommutative Orlicz spaces
Abstract We establish very general criteria for the existence of multiplication operators between noncommutative Orlicz spaces L ψ0 and Lψ1 . We then show that these criteria contain existing
Dynamics on Noncommutative Orlicz Spaces
Quantum dynamical maps are defined and studied for quantum statistical physics based on Orlicz spaces. This complements earlier work [26] where we made a strong case for the assertion that
Weighted Noncommutative Banach Function Spaces
We review the concept of a weighted noncommutative Banach function space. This concept constitutes a generalisation of the by now well-known theory of noncommutative Banach function spaces associated
Kadec–Klee property for convergence in measure of noncommutative Orlicz spaces
Abstract This paper studies the Kadec–Klee property for convergence in measure of noncommutative Orlicz spaces L φ ( M ˜ , τ ) , where M ˜ is the space of τ -measurable operators, and φ is an Orlicz
Noncommutative Yosida–Hewitt theorem in noncommutative Calderón–Lozanovskiĭ spaces
Let $${\mathcal {M}}$$ be a diffuse von Neumann algebra equipped with a fixed faithful, normal, semi-finite trace and let $$\varphi$$ be an Orlicz function. In this paper, a new approach to the
On Applications of Orlicz Spaces to Statistical Physics
We present a new rigorous approach based on Orlicz spaces for the description of the statistics of large regular statistical systems, both classical and quantum. The pair of Orlicz spaces we
Multiplication operators on non-commutative spaces
Abstract Boundedness and compactness properties of multiplication operators on quantum (non-commutative) function spaces are investigated. For endomorphic multiplication operators these properties
Quantum dynamics on Orlicz spaces
Quantum dynamical maps are defined and studied for quantum statistical physics based on Orlicz spaces. This complements earlier work [W. A. Majewski, L.E. Labuschagne, Ann. H. Poincare. 15,


A reduction method for noncommutative L_p-spaces and applications
We consider the reduction of problems on general noncommutative L p -spaces to the corresponding ones on those associated with finite von Neumann algebras. The main tool is an unpublished result of
Non-commutative Banach Function Spaces
In this paper we survey some aspects of the theory of non-commutative Banach function spaces, that is, spaces of measurable operators associated with a semi- finite von Neumann algebra. These spaces
Noncommutative Köthe duality
Using techniques drawn from the classical theory of rearrangement invariant Banach function spaces we develop a duality theory in the sense of Kothe for symmetric Banach spaces of measurable
A Radon-Nikodym theorem for von Neumann algebras
In this paper we present a generalization of the Radon-Nikodym theorem proved by Pedersen and Takesaki. Given a normal, semifinite and faithful (n.s.f.) weight $\phi$ on a von Neumann algebra M and a
Fully symmetric operator spaces
It is shown that certain interpolation theorems for non-commutative symmetric operator spaces can be deduced from their commutative versions. A principal tool is a refinement of the notion of Schmidt

Quantum L_p and Orlicz spaces
Let $\A$ ($\cM$) be a $C^*$-algebra (a von Neumann algebra respectively). By a quantum dynamical system we shall understand the pair $({\A}, T)$ ($({\cM}, T)$) where $T : {\A} \to {\A}$ ($T : {\cM}

In this paper we characterize the composition operators on Orlicz spaces and study some of their properties.

Let M μ be the set of all probability densities equivalent to a given reference probability measure μ. This set is thought of as the maximal regular (i.e., with strictly positive densities)
