Elementary equivalence and disintegration of tracial von Neumann algebras
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
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.

Free analysis and planar algebras
We study 2-cabled analogs of Voiculescu's trace and free Gibbs states on Jones planar algebras. These states are traces on a tower of graded algebras associated to a Jones planar algebra.

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.

On outer elements of the noncommutative Hp spaces
In the article let M be a von Neumann algebra equipped with a faithful normal normalized tracial state t, A be subdiagonal subalgebra of M. We transfer the results of [4] to the case p < 1.

The Jordan lattice completion and a note on injective envelopes and von Neumann algebras
The article associates two fundamental lattice constructions with each regular unital real ordered Banach space (function system). These are used to establish certain results in the theory of operator algebras, specifically relating the injective ...

NONCOMMUTATIVE DE LEEUW THEOREMS
Let $\text{H}$ be a subgroup of some locally compact group $\text{G}$. Assume that $\text{H}$ is approximable by discrete subgroups and that $\text{G}$ admits neighborhood bases which are almost invariant under conjugation by finite subsets of $\text{H}$.

Lifting Invertibles in von Neumann Algebras [PDF]
Given B ( H ) \mathcal {B}(\mathcal {H}) , the algebra of bounded operators on a separable Hilbert space H \mathcal {H} , and K \mathcal {K} , the ideal of compact operators, it is a well-known fact that T

Factorization of operators on $C^*$-algebras
Let $A$ be a $C^*$-algebra. It is shown that every absolutely summing operator from $A$ into $\ell_2$ factors through a Hilbert space operator that belongs to the 4-Schatten- von Neumann class.

On a Heisenberg-Type Uncertainty Principle in von Neumann Algebras
A refinement of the Heisenberg uncertainty principle has been proved by Luo using Wigner–Yanase information. Generalizations of this result have been proved by Yanagi and by other scholars for regular Quantum Fisher Information in the matrix case.
