Graph von Neumann Algebras

Acta Applicandae Mathematicae, 2007
Let \(G\) be a countable directed graph with vertices \(V(G)\) and edges \(E(G)\). Let \(\mathbb{G}\) denote the graph groupoid of \(G\), which can be regarded as the free groupoid generated by the edges of \(G\) whose identity elements correspond to the vertices of \(G\).

Banach Algebras and Von Neumann's Inequality

Proceedings of the London Mathematical Society, 1979
We propose to investigate how far Von Neumann's type inequalities extend to various classes of Banach algebras related to uniform algebras and uniform algebras. Our approach also yields estimates for the growth of norms of homogeneous polynomials in several operators on a complex Hilbert space.

Preduals of von Neumann Algebras

Functional Analysis and Its Applications, 2003
In the paper under review, the author summarizes and sketches the proofs of the results given in the papers [Russ. J. Math. Phys. 10, 117--120 (2003; Zbl 1065.46039)] and [Adv. Stud. Contemp. Math., Kyungshang 7, 1--10 (2003; Zbl 1047.46042)]. The main results of the present paper are the following (from the abstract): (1) If the Banach space of a von ...

AlgebraicK-theory of von Neumann algebras

K-Theory, 1993
The paper is devoted to the computation of the algebraic \(K\)-group \(K_ 1({\mathcal A})\) and a closely related group \(K_ 1^ w ({\mathcal A})\) of a von Neumann algebra \({\mathcal A}\). First the authors define the algebraic \(K\)-group \(K_ 1 ({\mathcal A})\) as usual as being generated by bijective endomorphisms of finitely generated projective \(

CROSSED PRODUCTS OF VON NEUMANN ALGEBRAS

Russian Mathematical Surveys, 1971
The paper is concerned with von Neumann algebras with finite trace and their -automorphisms, and with crossed products. A detailed investigation is made of the problem of constructing hyperfinite factors of type II1 by means of crossed products. Some new results are obtained on subfactors of hyperfinite factors of type II1 and also some new information

Noncommutative Probability on von Neumann Algebras

Journal of Mathematical Physics, 1972
We generalize ordinary probability theory to those von Neumann algebras A, for which Dye's generalized version of the Radon-Nikodym theorem holds. This includes the classical case in which A is an Abelian von Neumann algebra generated by an observable or complete set of commuting observables.

The Haagerup Invariant for Von Neumann Algebras

American Journal of Mathematics, 1995
This fascinating paper is concerned with approximation properties for operator spaces. The paper describes five approximation constants \(\Lambda(X)\), \(\Lambda_1(X)\), \(\Lambda_2(X)\), \(\Lambda_3(X)\) and \(\Lambda_4(X)\) associated with each operator space \(X\). The first coincides with the Haagerup invariant of a \(W^*\)-algebra \(M\) when \(X\)

C*-Algebras and von Neumann Algebras

1979
C*-algebra theory is an abstraction of the structure of certain algebras of bounded operators acting on a Hilbert space and is simultaneously a special case of the theory of Banach algebras. Consequently, the theory can be developed in two different ways.
