A multi-agent growth model based on the von Neumann-Leontief framework [PDF]

This paper presents a discrete-time growth model to describe the dynamics of a multi-agent economy, and the model consists of production process, exchange process, price and technology adjustment processes etc.

A note on faithful traces on a von Neumann algebra [PDF]

, 2006
In this short note we give some techniques for constructing, starting from asufficient family F of semifinite or finite traces on a von Neumann algebra M, a new trace which is ...

On Some Isomorphisms between Bounded Linear Maps and Non-Commutative Lp-Spaces

International Journal of Analysis and Applications, 2014
We define a particular space of bounded linear maps using a Von Neumann algebra and some operator spaces. By this, we prove some isomorphisms, and using interpolation in some particular cases, we get analogue of non-commutative Lp spaces.

Reflexivity of Murray-von Neumann algebras [PDF]

, 2016
A Murray-von Neumann algebra Af (R) is the algebra of operators affiliated with a finite von Neumann algebra R. Such an algebra contains both bounded and unbounded operators on a Hilbert space.

Invariant subspaces of von Neumann algebras. II [PDF]

, 1979
It is shown that every parareductive operator algebra A ⊂ B ( H ) A \subset B(H) (as defined below) is a von Neumann algebra.

Elementary equivalence and disintegration of tracial von Neumann algebras

Forum of Mathematics, Sigma
We prove an analog of the disintegration theorem for tracial von Neumann algebras in the setting of elementary equivalence rather than isomorphism, showing that elementary equivalence of two direct integrals of tracial factors implies fiberwise ...

Jordan (α,β)-Derivations on Operator Algebras

Journal of Function Spaces, 2017
Let A be a CSL subalgebra of a von Neumann algebra acting on a Hilbert space H. It is shown that any Jordan (α,β)-derivation on A is an (α,β)-derivation, where α,β are any automorphisms on A. Moreover, the nth power (α,β)-maps on A are investigated.

L1-space for a positive operator affiliated with von Neumann algebra [PDF]

, 2020
© 2016 Springer International PublishingIn this paper we suggest an approach for constructing an (Formula presented.)-type space for a positive selfadjoint operator affiliated with von Neumann algebra. For such operator we introduce a seminorm, and prove

On the function TreH+itK

International Journal of Mathematics and Mathematical Sciences, 2002
We prove, for two free semicircularly distributed selfadjoint elements a and b in a type II1 von Neumann algebra with faithful trace τ, that the function t∈ℝ↦τ(exp(a+itb)) is positive definite.
