The Category of Von Neumann Algebras
CoRR, 2018 In this dissertation we study the category of completely positive normal contractive maps between von Neumann algebras. It includes an extensive introduction to the basic theory of $C^*$-algebras and von Neumann algebras.

Algebra of operators affiliated with a finite type I von Neumann algebra [PDF]
, 2016 The aim of the paper is to prove that the -algebra of all (closed densely de ned linear) operators a liated with a nite type I von Neumann algebra admits a unique center-valued trace, which turns out to be, in a sense, normal.

Large N algebras and generalized entropy
Journal of High Energy Physics, 2023 We construct a Type II ∞ von Neumann algebra that describes the large N physics of single-trace operators in AdS/CFT in the microcanonical ensemble, where there is no need to include perturbative 1/N corrections. Using only the extrapolate dictionary, we

On some subalgebras of a von Neumann algebra crossed product [PDF]
, 1984 We study conditions for a nonselfadjoint subalgebra of a von Neumann crossed product L \mathcal {L} to be an algebra of analytic operators with respect to a flow on L \mathcal {L} .

ON SOME INEQUALITIES FOR 𝜏 -MEASURABLE OPERATORS
Проблемы анализа, 2019 This paper deals with the Choi’s inequality for measurable operators affiliated with a given von Neumann algebra. Some Young and Cauchy-Schwarz type inequalities for 𝜏 -measurable operators are also given.

An algebra of observables for de Sitter space
Journal of High Energy Physics, 2023 We describe an algebra of observables for a static patch in de Sitter space, with operators gravitationally dressed to the worldline of an observer. The algebra is a von Neumann algebra of Type II1.

DERIVATIONS OF MURRAY-VON NEUMANN ALGEBRAS [PDF]
, 2014 A Murray-von Neumann algebra is the algebra of operators affiliated with a finite von Neumann algebra. In this article, we study derivations of Murray-von Neumann algebras and their properties.

Business Strategy and the Environment, EarlyView.ABSTRACT Global imperatives, such as climate change, environmental concerns, and carbon emissions, make green transformation an inevitability in the logistics sector. Green logistics strategy formulation is an economic choice problem, but it also turns out to be a multicriteria decision‐making (MCDM) process that encompasses the triple bottom line (TBL)

Stochastic Gradient Descent in High Dimensions for Multi‐Spiked Tensor PCA
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT We study the high‐dimensional dynamics of online stochastic gradient descent (SGD) for the multi‐spiked tensor model. This multi‐index model arises from the tensor principal component analysis (PCA) problem with multiple spikes, where the goal is to estimate the unknown signal vectors within the N$N$‐dimensional unit sphere through maximum ...

Kochen-Specker theorem for von Neumann algebras [PDF]
, 2005 The Kochen-Specker theorem has been discussed intensely ever since its original proof in 1967. It is one of the central no-go theorems of quantum theory, showing the non-existence of a certain kind of hidden states models. In this paper, we first offer a
