Nonclassifiability of UHF $L^p$-operator algebras

, 2015
We prove that simple, separable, monotracial UHF $L^{p}$-operator algebras are not classifiable up to (complete) isomorphism using countable structures, such as K-theoretic data, as invariants.

Perturbations of nuclear C*-algebras

, 2009
Kadison and Kastler introduced a natural metric on the collection of all C*-subalgebras of the bounded operators on a separable Hilbert space. They conjectured that sufficiently close algebras are unitarily conjugate.

A Generalization of the First Tits Construction

Axioms
Let F be a field of characteristic, not 2 or 3. The first Tits construction is a well-known tripling process to construct separable cubic Jordan algebras, especially Albert algebras.

Jordan {g,h}-derivations on triangular algebras

Open Mathematics, 2020
In this article, we give a sufficient and necessary condition for every Jordan {g,h}-derivation to be a {g,h}-derivation on triangular algebras. As an application, we prove that every Jordan {g,h}-derivation on τ(N)\tau ({\mathscr{N}}) is a {g,h ...

Graphical Classification of Entangled Qutrits [PDF]

Electronic Proceedings in Theoretical Computer Science, 2012
A multipartite quantum state is entangled if it is not separable. Quantum entanglement plays a fundamental role in many applications of quantum information theory, such as quantum teleportation.

Completely Separating Algebras

Journal of Algebra, 1994
An algebra \(A\) is called completely separating if every convex subalgebra of \(A\) satisfies the so-called (s)-condition [see \textit{R. Bautista} and \textit{F. Larrión}, J. Lond. Math. Soc., III. Ser. 264, 43-52 (1982; Zbl 0501.16030)]. The aim of this paper is to present the basic properties and characterization of completely separating algebras ...

Physics‐Constrained Constitutive Learning of Rate‐Limiting Timescales for Efficient Hydrogen‐Based Direct Reduction for Green Steel Making

Advanced Science, EarlyView.
A conversion‐resolved constitutive framework is developed for the hydrogen‐based direct reduction of iron oxide pellets. Effective reaction and transport timescales are inferred directly from measured trajectories and mapped against operating conditions, pellet architecture, and composition. The analysis reveals how late‐stage transport control emerges

Nuclearity and ${\mathrm {CPC}^*}$ -Systems

Forum of Mathematics, Sigma
We write arbitrary separable nuclear $\mathrm {C}^*$ -algebras as limits of inductive systems of finite-dimensional $\mathrm {C}^*$ -algebras with completely positive connecting maps. The characteristic feature of such ${\mathrm {CPC}^*}$

Separable subalgebras of a class of Azumaya algebras

International Journal of Mathematics and Mathematical Sciences, 1998
Let S be a ring with 1, C the center of S, G a finite automorphism group of S of order n invertible in S, and SG the subnng of elements of S fixed under each element in G. It is shown that the skew group ring S*G is a G′-Galois extension of (S*G)G′ that

Dictionary‐based weak‐form training for noise‐robust series hybrid models with multiplicative unknowns

AIChE Journal, EarlyView.
ABSTRACT Hybrid modeling combines first‐principles equations with a data‐driven subcomponent. Training for the data‐driven part is sensitive to measurement noise when training targets are constructed using pointwise time derivatives. Beyond differentiation errors, hybrid models involve solving an inverse problem to estimate the data‐driven term, which ...
