2-local derivations on semi-finite von Neumann algebras
, 2012 In the present paper we prove that every 2-local derivation on a semi-finite von Neumann algebra is a derivation.Comment: 3 ...

Publicationes mathematicae (Debrecen), 2005 It is known that the automorphisms of the Hilbert space effect algebras equipped with Jordan triple product, where Hilbert space is of dimension not less than three, are implemented by unitary or antiunitary operators.

Noncommutative geometry of algebraic curves
, 2009 A covariant functor from the category of generic complex algebraic curves to a category of the AF-algebras is constructed. The construction is based on a representation of the Teichmueller space of a curve by the measured foliations due to Douady ...

On embedding of the Bratteli diagram into a surface
, 2008 We study C*-algebras O_{\lambda} which arise in dynamics of the interval exchange transformations and measured foliations on compact surfaces. Using Koebe-Morse coding of geodesic lines, we establish a bijection between Bratteli diagrams of such algebras

Class-preserving automorphisms of universal hyperlinear groups [PDF]
, 2013 We show that the group of class-preserving automorphisms of a universal hyperlinear group has index 2 inside the group of all automorphisms.Comment: 4 ...

On diagonal quasi-free automorphisms of simple Cuntz-Krieger algebras
, 2018 We show that an outer action of a finite abelian group on a simple Cuntz-Krieger algebra is strongly approximately inner in the sense of Izumi if the action is given by diagonal quasi-free automorphisms and the associated matrix is aperiodic.

Nonlinear maps preserving bi-skew Lie triple product on factor von Neumann algebras
Demonstratio MathematicaLet A $\mathcal{A}$ and B $\mathcal{B}$ be two factor von Neumann algebras with dimensions greater than 1. It is proved that if a bijective map Φ:A→B ${\Phi} : \mathcal{A}\to \mathcal{B}$ satisfies Φ([[A,B]⋄,C]⋄)=[[Φ(A),Φ(B)]⋄,Φ(C)]⋄ ${\Phi}\left ...

Conjugate Dynamical Systems on C*-algebras
, 2012 Let $(A, \alpha)$ and $(B, \beta)$ be C*-dynamical systems where $\alpha$ and $\beta$ are arbitrary *-endomorphisms. When $\alpha$ is injective or surjective, we show that the semicrossed products $A \times_\alpha \mathbb{Z}$ and $B \times_\beta \mathbb ...

On the normalizer of certain subalgebras of group-measure factors
, 1982 We study operator algebras constructed from ergodic actions of discrete groups on compact Lebesgue spaces. We show that under appropriate conditions, the normalizer of a subalgebra corresponding to a quotient action depends on the relative elementary ...

2-local triple derivations on von Neumann algebras [PDF]
, 2014 We prove that every {\rm(}not necessarily linear nor continuous{\rm)} 2-local triple derivation on a von Neumann algebra $M$ is a triple derivation, equivalently, the set Der$_{t} (M)$, of all triple derivations on $M,$ is algebraically 2-reflexive in ...
