The quotient algebra of a finite von Neumann algebra [PDF]
Pacific Journal of Mathematics, 1971 We will prove the following: Let M be a finite von Neumann algebra with center Z and A a von Neumann subalgebra of Z. Let Ω be the spectrum space of A and identify A with C(Ω). Let e be a σ-weakly continuous linear map of M onto A such that e(x*x) = e(a%c*) ^ 0 for every xeM, e(ax) — ae(x) for every a e A and xeM, e(l) = 1 and e(x*x) Φ 0 for every ...

Linear Mechatronic Modeling of Rectangular Tank Sloshing Dynamics
International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT Sloshing dynamics in partially filled tanks can strongly influence system‐level behavior when fluid motion couples with rigid‐body dynamics. This paper presents a linear and acausal two‐dimensional sloshing model for rectangular tanks, based on the reformulation of established sloshing theory within a modular, multi‐domain modeling framework ...

Nonlinear Skew Lie-Type Derivations on ∗-Algebra [PDF]
, 2023 Let A be a unital ∗-algebra over the complex fields C. For any H1,H2∈A, a product [H1,H2]•=H1H2−H2H1* is called the skew Lie product. In this article, it is shown that if a map ξ : A→A (not necessarily linear) satisfies ξ

Computing Skinning Weights via Convex Duality
Computer Graphics Forum, EarlyView.We present an alternate optimization method to compute bounded biharmonic skinning weights. Our method relies on a dual formulation, which can be optimized with a nonnegative linear least squares setup. Abstract We study the problem of optimising for skinning weights through the lens of convex duality.

Topos-Theoretic Approaches to Quantum Theory [PDF]
, 2012 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,

On the von Neumann algebra of an ergodic group action [PDF]
, 1977 We give a criterion that an ergodic action be amenable in terms of the operator algebra associated to it by the Murray-von Neumann construction.

Is There Intersectional Labor Market Discrimination?
Industrial Relations: A Journal of Economy and Society, EarlyView.ABSTRACT We test for intersectional labor market discrimination across five dimensions: gender, race, ethnicity, sexual orientation, and disability. Specifically, we test for “amplifying intersectionality”—negative interactions between the effects of marginalized identities that make wage penalties greater than additive.

Nonlinear Mixed Jordan-Type Derivations on ∗-Algebra
AxiomsLet A be a unital ∗-algebra over the complex fields C. In this article, it is proved that a nonlinear mixed bi-skew Jordan n-derivation is an additive ∗-derivation under certain conditions.

A spectral analysis extension to DEMATEL for strategic leverage points identification
International Transactions in Operational Research, EarlyView.Abstract Efforts to intervene in complex systems often emphasize influential factors, yet system behavior is equally shaped by the relationships among them. Methods such as Decision‐Making Trial and Evaluation Laboratory (DEMATEL) map causal structures but remain descriptive and do not identify which relationships provide the greatest leverage for ...
