Free entropy theory and rigid von Neumann algebras
In this thesis, we study rigid von Neumann algebras from the framework of Voiculescu’s free probability. A rigid von Neumann algebra or a Property (T) von Neumann algebra generalizes the well known notion of Property (T) for groups.

On the Modular Theory of von Neumann Algebras [PDF]
The purpose of this thesis is to provide an exposition of the \textit{modular theory} of von Neumann algebras. The motivation of the theory is to classify and describe von Neumann algebras which do not admit a trace, and in particular, type III factors.

On the geometry of von Neumann algebra preduals [PDF]
Let M be a von Neumann algebra and let M⋆ be its (unique) predual. We study when for every φ∈M⋆ there exists ψ∈M⋆ solving the equation ∥φ±ψ∥=∥φ∥=∥ψ∥. This is the case when M does not contain type I nor type III1 factors as direct summands and it is false

Topos-Theoretic Approaches to Quantum Theory [PDF]
Starting from a naive investigation into the nature of experiments on a physical system one can argue that states of the system should pair non-degenerately with physical observables. This duality is closely related to that between space and quantity, or,

A Topos Perspective on the Kochen-Specker Theorem: III. Von Neumann Algebras as the Base Category [PDF]
We extend the topos-theoretic treatment given in previous papers of assigning values to quantities in quantum theory, and of related issues such as the Kochen-Specker theorem.

Correspondences of von Neumann algebras.
In the early 1980's, Alain Connes introduced a morphism between von Neumann algebras in order to define a property formerly defined only for groups and extending Kazhdan's property T. This morphism is called a correspondence. Let ${\cal M}$ and ${\cal N}$

Multiplicity theory of projections in abelian von neumann algebras [PDF]
La teoría de multiplicidad espectral se generaliza para las proyecciones en un algebra conmutativa de von Neumann. La bien conocida descomposición de un álgebra de tipo I de von Neumann en una suma directa de álgebras de tipo In se deduce como una ...

Representations of von Neumann Algebras and Ultraproducts
© 2020, Springer Science+Business Media, LLC, part of Springer Nature. We will introduce the concept of ergodicity of states with respect to some group of transformations on a von Neumann algebra and its properties are studied.

Introducing Formalism in Economics: The Growth Model of John von Neumann [PDF]
The objective is to interpret John von Neumann's growth model as a decisive step of the forthcoming formalist revolution of the 1950s in economics.
